Secure Sockets Layer (SSL) is the technology responsible for data authentication and encryption for internet connections. It encrypts data being sent over the internet between two systems (commonly between a server and a client) so that it remains private. And with the growing importance of online privacy, an SSL port is something you should get familiar with.

Because data can be sent with or without the use of SSL, one way to indicate a secure connection is by the port number. By default, HTTPS connections use TCP port 443. HTTP, the unsecure protocol, uses port 80.

Commonly used TCP ports

For those responsible for configuring and managing web hosting, it’s useful to know the numbers for common services, such as an SSL port. Use the tables below to quickly look up port numbers and their basic functions. You can also see the full list of common server ports in our Help Center.

You can see which ports GoDaddy uses for cPanel in the GoDaddy Help Center .

How does HTTPS and SSL work?

HTTP is not a separate protocol from HTTPS . Rather, HTTPS works by establishing a secure HTTP connection using SSL. Hence, the protocol stacks for HTTP and HTTPS look similar:

The only difference is that HTTPS runs over SSL. To create this secure internet connection, an SSL certificate is installed on a web server . The SSL certificate authenticates an organization’s identity to activate the HTTPS protocol so that data can be passed securely from a web server to a web browser.

Distinguishing between certificates and protocols

The HTTPS protocol and an SSL certificate are two different — but critical — factors in creating a secure internet connection.

  • The HTTPS protocol provides the channel by which data is encrypted and transferred securely.
  • SSL certificates are simply used to authenticate critical information when an internet user attempts to send information over a secure connection.

Therefore, the secure connection is determined by your server configuration and not by the certificate itself.

What is the difference between SSL and TLS?

Transport Layer Security (TLS) is an update to the SSL protocol. The original SSL protocol was developed by Netscape back in 1995  and released to the public as SSL 2.0. Since that time, updates have been made to ensure stronger, more secure encryption.

In 1999, TLS 1.0 was released as an update to SSL 3.0. Since then, TLS has been the primary technology used to secure data over internet connections and SSL. However, because the term SSL is more widely-known, the name carries on despite the technology depreciating.

Why should I worry about my SSL port?

Seemingly a small nuance, your SSL port is important for a number of reasons. For starters, HTTP is falling out of favor. In fact, more than 97 percent of web pages are loaded via HTTPS in Google Chrome in the United States, according to Google’s HTTPS Transparency Report . Besides the reason that “everyone else is doing it,” there are a ton of advantages to using HTTPS as opposed to HTTP.

Limit exposure to criminal activity by using SSL

HTTPS offers an additional layer of protection against digital eavesdropping , whereby criminals monitor network activity to steal valuable information like login credentials. Because HTTPS is encrypted, it helps to thwart this type of criminal activity.

HTTPS is required for PCI compliance

If you collect credit card information on your website, then you are required by the Payment Card Industry  to use HTTPS.

HTTPS is capable of loading web pages faster than HTTP

Not only does HTTPS make for a more secure browsing experience, it can also positively impact the load times of your site content. If you need proof, see for yourself .

Create a more trustworthy web browsing experience

Most major web browsers indicate whether or not a site is secure in the address bar with a padlock icon or the word “secure.”

SSL can boost your SEO

HTTPS is preferred by major search engines and is generally considered beneficial for SEO. It is crucial that you implement HTTPS correctly and take a few extra steps to ensure you reap the SEO benefits. Follow this HTTPS migration checklist  for SEO to make sure you get it right.

How do I get SSL?

SSL certificates can be purchased from a Certificate Authority (CA), like GoDaddy. After you purchase the certificate, follow the instructions from your hosting provider to install the SSL certificate , or get GoDaddy Managed SSL so we can handle the install and maintenance of your SSL certificate.

HTTPS Protocol: What is the Default Port for SSL & Common TCP Ports

HTTPS Protocol: What is the Default Port for SSL & Common TCP Ports

SSL port numbers serve as communication endpoints for transmitting or receiving data. One of the primary functions of these ports is to establish a secure connection between a web page and a website hosting server or the CDN/WAF that might sit in front of it. These add an extra layer of security by leveraging either Secure Sockets Layer (SSL) or Transport Layer Security (TLS) certificates for encryption.

At their core, HTTPS ports are identified using numerical codes. For instance, your web browser might use network port 443 to connect to your website’s hosting server for secure HTTPS connections.

In this post, we’ll take a look at the most common default ports for HTTPS and explain how HTTPS and SSL certificates work together to encrypt and secure your website’s data.

What is a port number?

What is the difference between ssl and the https protocol, what is the default port for https, what are the most common tcp ports.

  • What’s the difference between SSL and TLS?
  • What OSI levels do SSL/TLS and HTTPS operate on?

How can I get HTTPS on my website?

A port number serves as a unique identifier for specific processes to which network messages are directed upon reaching a server. Every network-connected device features standard ports with uniquely assigned numbers, each designated for a specific protocol and function.

For instance, one of the most frequently used ports, port 80, is always assigned to HTTP messages. The idea of port numbers, initially termed as socket numbers, was proposed by the Advanced Research Projects Agency Network’s developers, and bears a similarity to the class of Internet Protocol (IP) addresses in use today.

SSL is the technology used to encrypt data for internet connections, ensuring data transmission between a website and server remains secure. The HTTPS protocol, however, refers to the method of using SSL (or its successor, TLS) on a specific port to create a secure connection.

In essence, HTTPS operates over SSL on a web server with an SSL private key, and on the browser with an SSL certificate, leveraging the Public Key Infrastructure (PKI) to confirm legitimacy.

While both SSL and HTTPS work together, they have different roles. SSL (now largely replaced by the more efficient TLS) authenticates user identity when data is sent. The key difference is that only HTTPS ensures a secure channel for transmitting encrypted data.

A website with an SSL certificate typically has HTTPS in its URL and displays a padlock icon next to the domain name.

HTTPS port connection on a secure website connection with an SSL certificate

Default HTTPS connections use TCP port 443 to facilitate encrypted communications between the web browser and server. This encryption ensures a secure data exchange during a website visit.

In contrast, the unsecured HTTP protocol uses TCP port 80 . Overall these HTTPS ports, differentiated by unique numbers, heighten security by employing SSL or TLS encryption for website interactions.

What is the difference between port 443 and port 8443?

HTTPS port 443 and port 8443 differ mainly in their usage; 443 is a standard web browsing port designed for secure data transmission between web browsers and servers, while 8443 is used less frequently by Apache Tomcat for SSL text service to prevent conflicts. Even though both are HTTPS ports, Tomcat specifically defaults to 8443 . Tomcat is rarely seen being used on public websites.

Here is a list of the most common TCP ports for web services like HTTP, SSL, cPanel, and SMTP.

cPanel Ports

Email ports, what is the difference between ssl and tls.

Secure Sockets Layer (SSL) is an established protocol that forges a secure connection between two devices or applications on a network. It’s instrumental in establishing trust and authenticating the opposite party prior to sharing credentials or data online. Despite its wide usage in applications or browsers for creating an encrypted communication channel, SSL is an older technology that comes with certain security shortcomings.

Transport Layer Security (TLS) is essentially an improved version of SSL, designed to address and fix vulnerabilities present in SSL. With its more efficient authentication process, TLS is a more secure and reliable option compared to its earlier counterpart.

SSL vs. TLS: Comparison Table

What osi model levels do ssl/tls and https operate on.

The Open Systems Interconnection (OSI) is a framework that divides the various functions of network communications into seven different layers. Ports are found at the Transport Layer 4 of the OSI model.

OSI Model Application Layers 1 to 7 for HTTP SSL port connection

SSL and TLS operate between layers 4 and 7, while HTTPS itself is found on Application Layer 7.

What is the difference between an SSL certificate and TLS certificate?

Nowadays, SSL certificates are technically obsolete, with TLS certificates taking their place as the industry norm — however, the term “SSL” is still commonly used to describe TLS certificates. The core functionality of both types of certificates remains the same, with TLS iterations improving on the original SSL model over time.

Despite this terminology overlap, modern SSL certificates support both SSL and TLS protocols, underlining the importance of ensuring server configurations are compatible with progressively mandatory TLS protocols.

SSL v1.0 through to v3.0 and TLS 1.1 should be considered insecure; its use would nullify any PCI compliance .

To add HTTPS to your website, you’ll need to install an SSL certificate or get one through a provider. Obtaining an SSL certificate for your website can be simplified by purchasing one from a certificate authority like GoDaddy or acquiring a free one from Let’s Encrypt. Your hosting provider may already provide an SSL certificate — so it’s worth verifying with them first to avoid unnecessary work.

If you’re using the Sucuri Web Application Firewall (WAF) , SSL will be enabled on your firewall servers by default — even without an SSL certificate on the website’s origin server. This ensures encryption of data between visitors and the viewed web page. Despite this, having an SSL certificate on your origin server is still essential.

What Is a TLS/SSL Port?

Posted on August 26, 2022 · 4 minute read ·  by   Alexa Hernandez

What Is a TLS/SSL Port? - cover graphic

When using computer systems and software, there is constant communication happening within the network. In order to make this communication process work, there has to be several parts. For example, with a telephone, there needs to be a sender, receiver, and a signal to connect the two. Ports are both a sending and receiving point and have specific numbered addresses for the system to know where the information is being sent. These ports are programmed to direct traffic to the right places, or in other words, they are the helpers that direct systems involved to identify which service is being requested. Services range anywhere from handling unencrypted HTTP web traffic with port 80 to port 21, FTP, which transfers information and files between clients and servers. There are 65,535 ports, but not all are used every day. The TLS/SSL certificate port, however, is one of the most commonly used ports and is definitely used on a daily basis. So what port is TLS/SSL? The TLS/SSL port is port 443, HTTPS, and uses the TLS/SSL certificates to keep the port connections secure. HTTP is port 80 and is the unsecure protocol port.

What tcp ports are used most frequently for tls/ssl certificates.

Managing TLS/SSL certificates means also having the right knowledge on hand when it comes to security and network connections. It may therefore be useful to know what some of the most common TCP (or transmission control protocol) ports are.

We’ve compiled a list of these common TCP ports and what their functions are for reference.

Unsecured port numbers and their function:

Secured port numbers and their function:

What is port 443 used for?

As mentioned previously, port 443 uses the TLS/SSL certificates to keep the port connections secure. TLS/SSL certificates' main function is to secure information so that web traffic or cybercriminals can’t access the moving information. This is why many companies use HTTPS over HTTP in order to protect their information from being exposed or stolen while it is being sent and received.

HTTP vs HTTPS and SSL vs TLS: how they work together

Http vs https.

HTTP and HTTPS are not 2 separate protocols. Rather, HTTPS is a specified version of HTTP since it specifically uses TLS/SSL certificates. HTTPS is therefore just a more secure version of HTTP and is safer to use to transfer information.

SSL certificates are an outdated term for what are now called TLS certificates . They essentially perform the same security functions, a lot of people are still using the term SSL while others are using TLS. It’s important to remember that they are the same thing, which is why TLS/SSL is one of the more common ways to refer to the certificates so that people can understand that they are the same.

How it all works together

The default network will start as HTTP. In order to make your network secure, you’ll need to install a TLS/SSL certificate onto the web server that you are using. Once this is done, the ​​certificate will authenticate your organization’s identity to start up the HTTPS protocol. This will ensure that data can be transferred securely from a web server to a web browser.

Why are SSL ports important?

You may be wondering why your network server needs an SSL port over other ports and methods of internet communication. TLS/SSL certificates are going to be your most reliable ticket to a safe transfer of information. While safety is incredibly important, here are are few other things to consider:

PCI compliance requires HTTPS usage: In order to have any type of online payments, you have to be compliant with the Payment Card Industry. This will also keep both your information and your customer’s information safe.

Cybercrime: With more businesses, users and internet hackers using the internet every day, it’s safe to say that security is of the utmost importance now more than ever. Keeping your business safer by using an SSL certificate port is going to be one of your best preventative measures to take when it comes to cyber security.

HTTPS is faster than HTTP: If you have a TLS/SSL certificate protected page making it HTTPS, then your information will likely load much faster than on an HTTP page.

Managing TLS/SSL certificates and ports

Keeping your applications secure often comes down to effective management of TLS certificates. Using TLS/SSL certificates is a vital first step. But many companies forget that it’s also important to protect them against misuse and compromise. Protect your network by learning the basics of machine identity management.

What is SSL Certificate Port? – Ultimate Technical Guide SSL Port

Secure Socket Layer (SSL) certificates are not new anymore. Web owners are becoming aware of the importance of these certificates and how they encrypt browser-server communications to keep their website data safe from hackers.

These certificates secure digital infrastructures with 256-bit encryption security and ensure data integrity, owner authentication, and site authentication.

Privacy is maintained between the server and the client, which is very pivotal in today’s world. The SSL port is one such port that ensures this privacy. Irrespective of an SSL certificate being installed on a website or not, a port number indicates whether the connection is a secured one or not.

The default TCP port for all HTTPS (hyper-text transfer protocol secure) connections is 443, whereas HTTP (hyper-text transfer protocol) connections use the unsecured port 80.

What is an SSL Certificate Port?

There are ample internet ports, all having different numbers, and each of them offers unique services. They are also called TCP (Transmission Control Protocol) Ports.

As stated above, SSL does not have any specific port, but the HTTPS protocol, which uses SSL security, uses port 443 . So, HTTPS indicates the existence of an SSL certificate in the URL.

Data communication can be done with or without the existence of an SSL certificate. But the port number indicates whether your connection is a secured one or not.

Port for SSL (port 443) identifies the security of your connections, i.e., it specifies a secured connection.

Commonly used TCP Ports:

It’s essential to know the usual functionalities of each port number while configuring or managing web hosting accounts.

We live in a world of neologism, where the most convenient and popular word is frequently used. The same logic applies to TLS (Transport Layer Security) and SSL certificates.

TLS is the replacement protocol for SSL. Though the majority of the web owners prefer this updated version, they still stick to the term SSL thus making this protocol widely popular.

TLS and SSL are the same, but the term SSL certificate is widely used, and hence port 443 is listed as “SSL certificate port 443”.

It’s just a difference of terminologies, but the fact remains that HTTPS protocol which uses port 443, is sometimes termed as SSL certificate port 443.

How do HTTPS and SSL work?

The term HTTPS has just an extra “S,” which stands for security, compared to the term HTTP.

HTTPS connection = HTTP Connection + SSL Certificate Security

Thus, the protocol stacks are the same for both these terms.

For establishing a secured internet connection, the installation of an SSL certificate is a must. When this security certificate is installed on the webserver, it authenticates the organization and the website owner for initializing the HTTPS protocol.

This, in turn, secures the data transmissions between the client and the server.

Difference between Certificates and Protocols:

The “SSL certificate” and the “HTTPS Protocol ” are two distinct factors, but they both work on establishing a secure gateway for the passing of information.

  • The SSL certificate first authenticates the data. Post authentication encrypts this data and shares it on the HTTPS protocol.
  • The HTTPS protocol is a digital infrastructure that uses port 443 to pass on the secured information between 2 parties, i.e., the client and the server .

Once the SSL certificate is installed and configured on the webserver, it will encrypt the information and secure it from cyber-criminals.

Distinguishing between SSL and TLS?

Why should you worry about your ssl port.

Don’t ignore your SSL port. It’s important for ample reasons. Firstly, HTTP has been giving away ever since browsers started displaying “Not Secure” messages on HTTP sites.

Secondly, Google too announced HTTPS as a ranking factor in SEO, and research indicates that 76% of the websites use the default HTTPS protocol .

Hence, HTTPS is far more advantageous than HTTP since a majority of the search engines, including Google, check the website’s security by its port number. Hence it makes sense to use a secured port for your website.

There are some more advantages of SSL port, which make web owners crave this security. Let’s check them out.

What is The Importance of SSL Port?

1. safeguards your website against cyber-criminals with the use of ssl:.

HTTPS is an additional security layer for data protection against intruders. These cyber-criminals try their evil methods to penetrate networks and steal data and login credentials. HTTPS ensures that this sensitive data is encrypted (coded text) to prevent intruders from accessing data.

2. HTTPS is Pivotal for PCI Compliance:

If you own an e-commerce store or a company where many financial transactions occur, HTTPS is a necessity as per PCI DSS (Payment Card Industry Data Security Standard).

It eases the user’s mind while online shopping since HTTPS implementation is essential as per PCI compliance.

3. HTTPS Enhances Trust & Security:

With the rising awareness about HTTPS, the majority of the customers are hesitant to punch their credit card information on HTTP sites. They also think twice before giving their sensitive data.

HTTPS enhances site security since SSL encryption security secures website data with 256-bit encryption.

Since the existence of an SSL certificate on a website portrays trust, customers check out the trust signs like HTTPS (in the URL) and a padlock (in the address bar). They are more assured about their data privacy with HTTPS and hence trust such sites.

4. Tough Call for Hackers due to Robust Encryption:

Hackers are becoming extremely smart and trying multiple ways to penetrate networks and systems. Varied advanced encryption algorithms like DSA, RSA, etc., encrypt the data and ensure its privacy from these prying eyes.

5. Fast Loading Speed as Compared to HTTP sites:

Website loading speed is a crucial factor affecting user experience and site performance, and it also adversely affects website ranking and bounce rate and benefits competitors. Web owners resort to multiple tricks to boost their site speed.

Since users are always in a hurry to get their information, they hate the website load time (if more than 2 seconds) and shift their focus to other competitive sites.

http vs https test

Source: https://www.httpvshttps.com/

HTTPS is one factor that helps fast load a website and saves the user’s time.

6. HTTPS helps to Boost SEO:

A majority of the search engines love HTTPS, and hence it is favorable for SEO too.

It’s necessary to implement HTTPS precisely and avail its security and SEO benefits, which boost customers’ trust and business finances.

7. Increase in Brand Value:

A rise in SEO due to HTTPS indirectly increases the brand value of your business. Maximum customers and a good ROI follow the same since your site will be visible in SERP (search engine result pages) results, increasing your brand reputation.

increase in brand value

HTTPS ensures a trustworthy browsing experience by showing a padlock in the address bar , which, when clicked, shows whether the connection is secured or not.

8. The Pros of Mobile Technology:

You can’t ignore the mobile internet traffic, and hence it is pivotal to make your website mobile-friendly.

Google’s Accelerated Mobile Pages (AMP) is essential to optimize your site for small screens. Google created it with the sole motto of increasing the website loading speed on mobile devices. Many may not be aware, but AMP content display is at the top of SERPs, and the same functions only with HTTPS sites.

Even the latest browsers and web apps are designed for HTTPS sites only, and hence if your site is HTTP, you are at a considerable disadvantage.

How do I Get SSL?

Multiple brands of SSL certificates are available in the market, and they secure your web infrastructure in different ways.

  • Comodo PositiveSSL certificate ($8/year) secure the root domain of your business website.
  • Comodo Multi-Domain SSL ($30/year) secure multiple domains and multiple sub-domains of all levels.
  • Comodo PositiveSSL Wildcard certificate ($45/year) secures the root domain with unlimited sub-domains.

clickssl

Thinking about where I found such attractive rates, right?

ClickSSL is a cheap SSL certificate provider offering such enticing rates on all SSL brands and products.

It also offers a reseller program which is quite profitable for IT businesses and other business owners who are willing to start their own web security business. You can set up your profit margins without any interference from ClickSSL and bloom your business.

Wrapping Up:

The HTTP protocol is an unsecured protocol and can easily be hacked by hackers because of its easy accessibility. The display of the information in plain text makes it a rich target.

But HTTPS protocol encrypts this plain text into ciphertext (coded form) with the help of an SSL certificate.

Not only does HTTPS permit secured e-commerce transactions, but the SSL security secures confidential data, thus instilling trust amongst the users.

Authentication of certificate owners and businesses is an added advantage. Thus, HTTPS enhances user trust and site security, giving web owners less choice for switching over to HTTPS.

So, grab your SSL certificate from ClickSSL now, and secure your digital infrastructure.

Port 443 Explained: What Is It and Why to Use It

What Is Port 443

In a world where secure internet use is no longer a luxury but a necessity, understanding the role of Port 443 is essential. This port, crucial for online security, is the gateway for HTTPS traffic, ensuring that your private information remains just that — private. As we increasingly rely on digital transactions and communications, knowing how Port 443 works with SSL/TLS to encrypt our data becomes vital.

This article explains the technical aspects of Port 443 and offers practical advice on managing it across different operating systems.

Table of Contents

What Is Port 443?

How does https work, what is port 443 used for, what are the port 443 vulnerabilities, how to open port 443.

Port 443 is the universal web browsing port for Hypertext Transfer Protocol Secure (HTTPS), the secure counterpart of HTTP. It’s like a guard who ensures that any data you send or get from websites is kept away from unwanted eyes. This port is crucial for making sure your online activities, like shopping, managing your finances, and emailing, are safe.

When you’re using HTTPS Port 443, your communication with websites is scrambled, keeping your personal details safe from those who shouldn’t see them. It’s a key player in keeping your online life private and secure, protecting a variety of online services that we rely on every day.

Today, web encryption is mandatory for all websites, regardless of size, type, or niche. If the connection between browsers and web servers is not secured, visitors can’t access the pages they want. Instead, they encounter an off-putting SSL connection warning calling them to leave the site immediately.

When users enter an HTTPS site, their web browser establishes a secure connection with the web server using the TLS  protocol. TLS encrypts data and ensures only the intended recipient can see it.

The communication between the web browser and the web server occurs through port 443, the default port for HTTPS traffic. SSL port 443 establishes a secure and encrypted connection between the web server and the web browser. Other HTTPS ports like 8443 or 2096 are also available for specific needs and connections.

To encrypt a website, you need to install an SSL certificate on your server. An SSL certificate is a small digital file that follow the TLS (Transport Layer Security) protocol and secure data in transit between two computers over a network. The best indicator of an encrypted website is the padlock icon next to the URL.

How does encrypted data look? It’s just a random string of characters impossible to decipher by cyber criminals. The HTTPS connections are bulletproof to eavesdropping and man-in-the-middle attacks.

HTTPS port 443 protects sensitive information transmitted between your web browser and website. Whenever you enter personal details like your credit card number, password, or any other private credentials, the HTTPS protocol 443 keeps that info safe from being intercepted by cyber thieves, thanks to TLS encryption.

Port 443, through HTTPS, encrypts this data, making it unreadable to anyone who might intercept it. This encryption is crucial for protecting against cyber threats like hacking and identity theft. By using HTTPS Port 443, websites and online services ensure our online activities are safe, maintaining trust and security in digital communications.

So, whenever you see the lock icon or the “https://” in the browser’s address bar, you can be sure that your communication with the website is via port 443 and your information is safe.

Port 443 has the same exposure as the HTTPS and TLS protocols. This port is vulnerable to:

  • SQL injections
  • Cross-site scripting
  • DDoS attacks
  • Cross-site request forgery
  • Man-in-the-middle (MITM) attacks , where a hacker intercepts the communication between the client and server to steal sensitive information.
  • SSL/TLS vulnerabilities , such as the Heartbleed bug, where attackers can steal private data. This issue is specific to older SSL versions and is not present in the current TLS 1.2 and TLS 1.3 protocols.
  • Malware infections , where attackers can exploit open ports to infect systems with malware.

Opening port 443 is typically done by configuring your firewall or router to allow incoming and outgoing web traffic on that port. The specific steps for opening port 443 will depend on the type of firewall or router you are using, as well as the operating system of your computer.

Open Port 443

Should Port 443 Be Open?

Whether or not you should open port 443 depends on your specific needs. If you want to access a website or service that uses HTTPS, port 443 should be open. Additionally, if you run a web server that uses HTTPS, you should ensure port 443 is enabled so that users can connect to your server securely.

Is Port 443 Open by Default?

Again, it depends on your firewall, router, and OS (operating system) configuration. Some platforms may have firewall port 443 open by default, while others may have it closed. It’s important to check your settings to see if port 443 is open or closed and to configure it accordingly if necessary. Most web servers use port 80 (HTTP) by default, and each server has specific instructions for opening port 443.

Below we provide instructions on how to open port 443 on Linux, Windows, and Mac.

How to Open Port 443 in Linux?

To enable Port 443 on Linux systems, run the commands below:

  • Run the following command to allow traffic on port 80: sudo iptables -I INPUT -p tcp -m tcp –dport 80 -j ACCEPT
  • Run the following command to allow traffic on port 443: sudo iptables -I INPUT -p tcp -m tcp –dport 443 -j ACCEPT
  • Run the following command to save the iptables rules: sudo service iptables save

If you want to open port 443 on Ubuntu, the same instructions apply.

How to Check if Port 443 Is Open in Linux?

You can use several commands like “netstat,” “ss” or “nmap” to check whether port number 443 is open on Linux. Here’s how to do it with “netstat” command:

  • Open the terminal on your Linux machine.
  • Type: sudo netstat -tulpn | grep :443
  • Press Enter

If the command returns any results, then port 443 is open on your system.

What is an SSL port? A technical guide for HTTPS

Adem Asha

Secure Sockets Layer (SSL) is the technology responsible for data authentication and encryption for internet connections. It encrypts data being sent over the internet between two systems (commonly between a server and a client) so that it remains private. And with the growing importance of online privacy, an SSL port is something you should get familiar with.

Because data can be sent with or without the use of SSL, one way to indicate a secure connection is by the port number.

Related: What’s an SSL ?

In this article we will discuss a few important points:

  • What are the commonly used TCP ports?

How does HTTPS and SSL work?

  • The difference between protocols and certificates
  • The difference between SSL and TLS
  • What is SSL port used for?

Commonly used TCP ports

For those responsible for configuring and managing web hosting, it’s useful to know the numbers for common services, such as an SSL port. Use the tables below to quickly look up port numbers and their basic functions.

You can see which ports GoDaddy uses for email — in addition to finding SSL port information — in the  GoDaddy Help Center .

You can see which ports GoDaddy uses for cPanel in the  GoDaddy Help Center .

HTTP is not a separate protocol from  HTTPS . Rather, HTTPS works by establishing a secure HTTP connection using SSL. Hence, the protocol stacks for HTTP and HTTPS look similar:

The only difference is that HTTPS runs over SSL. To create this secure internet connection, an SSL certificate is installed on a  web server .  The SSL certificate  authenticates an organization’s identity to activate the HTTPS protocol so that data can be passed securely from a web server to a web browser.

How do I find out my SSL port number?

By default, HTTPS connections use TCP port 443. HTTP, the unsecure protocol, uses port 80.

Distinguishing between certificates and protocols

The HTTPS protocol and an SSL certificate are two different — but critical — factors in creating a secure internet connection.

  • The HTTPS protocol provides the channel by which data is encrypted and transferred securely.
  • SSL certificates are simply used to authenticate critical information when an internet user attempts to send information over a secure connection.

Therefore, the secure connection is determined by your server configuration and not by the certificate itself.

What is the difference between SSL and TLS?

Transport Layer Security (TLS) is an update to the SSL protocol. The original SSL protocol was developed by Netscape  back in 1995  and released to the public as SSL 2.0. Since that time, updates have been made to ensure stronger, more secure encryption.

In 1999, TLS 1.0 was released as an update to SSL 3.0. Since then, TLS has been the primary technology used to secure data over internet connections and SSL. However, because the term SSL is more widely-known than TLS, the name carries on despite the technology depreciating.

Why should I worry about my SSL port?

Seemingly a small nuance, your SSL port is important for a number of reasons. For starters, HTTP is falling out of favour. In fact, more than 70 percent of web pages are loaded via HTTPS in Google Chrome in the United States, according to Google’s  HTTPS Transparency Report . Besides the reason that “everyone else is doing it,” there are a ton of advantages to using HTTPS as opposed to HTTP.

What is an SSL port used for?

SSL ports are required an used for a number of reasons, like:

1. Limit exposure to criminal activity by using SSL

HTTPS offers an additional layer of protection against  digital eavesdropping , whereby criminals monitor network activity to steal valuable information like login credentials. Because HTTPS is encrypted, it helps to thwart this type of criminal activity.

2. HTTPS is required for PCI compliance

If you collect credit card information on your website, then you are required by the  Payment Card Industry  to use HTTPS.

3. HTTPS is capable of loading web pages faster than HTTP

Not only does HTTPS make for a more secure browsing experience, it can also positively impact the load times of your site content. If you need proof,  see for yourself .

4. Create a more trustworthy web browsing experience

SSL Port Security

Most major web browsers indicate whether or not a site is secure in the address bar with a padlock icon or the word “secure.”

Web browsers, like Chrome, are moving towards alerting users when they’ve accessed a site that is not using HTTPS.

5. SSL can boost your SEO

HTTPS is preferred by major search engines and is generally considered beneficial for SEO. It is crucial that you implement HTTPS correctly and take a few extra steps to ensure you reap the SEO benefits.

How do I get SSL?

SSL certificates can be purchased from a Certificate Authority (CA), like  GoDaddy . After you purchase the certificate, follow the instructions from your hosting provider to  install the SSL certificate .

Securing Internet Connection: All about the SSL Port or Secured Ports

  • February 15, 2022
  • Aryne Leigh Monton

What is an SSL Port or Secured Port?

People and organizations exchange data digitally, be it public or sensitive information. This major feature of the internet increases the need for data security on the internet. An SSL Port, also known as Secured Port, utilizes Secure Sockets Layer (SSL) certificates to protect internet connections.

SSL technology’s main purpose is to keep internet connections secure through encryption and data authentication . In websites we access, our device forms a connection with the server. The SSL ensures that information transmitted over the internet remains private and protected by encrypting the data transferred between the server and the client, and the SSL port indicates whether the connection is secure or not.

SSL Certificate Port Number

There are various ports on the internet that are used for specific purposes. Web locations are isolated into four or seven layers, and the vehicle layers are where porting occurs. Ports are one way to indicate secure connections. All in all, there are 65,535 ports. It is useful for professionals to know port numbers of common functions, as summarized in the table below.

HTTPS uses port 443 to establish a secure connection. To be able to do so, you will need an SSL/TLS certificate.

What is Port 443 used for?

As previously mentioned, different ports serve different functions. Port 443 is the SSL function for HTTPS , used to transmit web pages securely through encryption techniques. Information that travels through port 443 is encrypted using SSL/TLS technology. This means that the connection is secure, and information is kept safe while in transit.

SSL Connection Port

The SSL connection port determines whether the connection is secure or not. While all unencrypted HTTP web traffic is handled by Port 80, Port 443 is used as an endpoint for transfer layer protocols like UDP and TCP.

SSL UDP or TCP

Transmission Control Protocol (TCP) and User Datagram Protocol (UDP) are communication protocols that can be used to transmit data across networks. Before defining these two protocols, let us first discuss what an internet protocol (IP) is.

IP is a network protocol and is a set of rules that dictate how data is transmitted from the sender to an intended recipient via a network. It is one of the seven layers of the open systems interconnection (OSI) model that guides how data is exchanged between systems. The seven layers are namely:

  • Physical layer
  • Data link layer
  • Network layer
  • Transport layer
  • Session layer
  • Presentation layer
  • Application layer

The TCP is a connection-oriented data communication method. This is part of the transport layer of the OSI model with the purpose of being an error-free method of transmission by ensuring that each recipient receives all data that has been sent and are received in their intended order. It follows a three-way handshake process – starting with the exchange of the flags SYN (synchronize), SYN-ACK (synchronize-acknowledgement), and ACK (acknowledgement). The flags are exchanged between entities, ensuring that a reliable and safe connection has been made.

On the other hand, UDP is a connectionless communication protocol. No connection is required to be established before sending data packets. Thus, no three-way handshake happens in the facilitation of data transmission. Therefore, data may not arrive complete or in the intended order but is expected to arrive faster than TCP.

Which is better, TCP or UDP?

Both TCP and UDP are useful in the facilitation of data exchange. However, there are pros and cons attached to each communication protocol and a more appropriate application scenario for each.

When it comes to data integrity and completeness, TCP is better than UDP. This is because TCP guarantees data delivery to the recipient, and that the data order is from sender to receiver is kept reliable. On the other hand, UDP may result in data losses due to its speed prioritization. TCP establishes reliable connections before data transmission and ensures that the intended recipient gets the full data, while UDP will send data regardless of whether there is a confirmation from the recipient or not.

However, the advantage of UDP comes in the speed of transmission. UDP ensures that the exchange is facilitated quickly, while TCP focuses on doing the transmission is done well, step by step through the three-way handshake. Thus, UDP is more advantageous in situations where data is needed in real-time, such as video games and chats. TCP, however, is more beneficial in situations where high data quality is needed but has room for lags or buffers. What is better between the two boils down to the purpose of data transmission.

Types of TCP and UDP – based on services

TCP and UDP are often used in different types of services. As previously discussed, TCP is used to ensure a high quality and error-free data transmission, while UDP is more concerned about having the data live and in real-time.

Common services that rely on TCP include:

  • World wide web
  • File transfer protocol
  • Email exchanges
  • Text exchanges

Meanwhile, UDP is more commonly used on:

  • DNS servers
  • Online gaming
  • Video conferencing

SSL Port for SMTP

The first internet service we usually think about when it comes to data transmission is email. Mail servers use Simple Mail Transfer Protocol (SMTP) to deliver an email from the sender to the recipient. Given that it is common to send emails containing sensitive information, it is very important to know the port for secure transfers.

In today’s standards, the SSL port used for SMTP is Port 587. This is considered the default mail submission port. Historically, Port 25 was used, but various local ISPs have been blocking Port 25 due to spam.

SSL Port for IMAP

IMAP, or Internet Message Access Protocol, is an incoming email protocol mainly used for standard email retrieval. The IMAP stores messages and allows a client to access messages remotely as if emails were on local devices.

The IMAP port used for SSL is Port 993. This is used to connect using IMAP securely. Port 143 is also used for TLS.

HTTPS vs SSL vs TLS

All created with the goal of protecting data, HTTPS, SSL, and TLS are all related to cybersecurity techniques used to secure information against man-in-the-middle attacks while in transit.

SSL is an encryption-based secure protocol developed for protecting information on the internet. This is developed to ensure data integrity and privacy for data that have been in transit. This was initially developed in 1995, with another version released in 2015.

Meanwhile, TLS, or Transport Layer Security, is the successor of SSL. The TLS is a cryptographic protocol that is also designed to provide security. This is seen as an improved version of the SSL using more advanced encryption techniques.

Both SSL and TLS can be used to secure networks. These are both encryption protocols on top of HTTP.

Hypertext Transfer Protocol (HTTP) is generally the communication protocol used to connect to web servers on the internet. By using SSL or TLS, HTTP becomes encrypted, and this is known as Hypertext Transfer Protocol Secure (HTTPS). The attached encryption adds a layer of protection and establishes a secure connection.

SSL certificates

The importance of data integrity and privacy have been highlighted in today’s remote environment. To facilitate secure connections, an SSL certificate should be used. SSL certificates are digital certificates used to authenticate the identity of a website and enable an encrypted connection. This is relevant for organizations – SSL certificates can be used not only to protect the organization but also their customers by preventing man-in-the-middle attacks. Customer information such as personal data and financial details can be kept safe and private using SSL certificates.

SSL certificates ensure that data is encrypted and is impossible to read by other parties, except for the intended recipient. In the process, an SSL handshake is formed, making the connection secure.

While there are many SSL vendors in the market, GlobalSign is one of the most trusted providers . GlobalSign issues SSL certificates at different validation levels, catering to the needs of every organization.

Our SSL certificates ensure your website is protected and meets the demands of today's modern sites.

What is a TLS/SSL Port?

TLS/SSL certificates

Within the network, constant communication is always happening while using computer systems and software. There must be various components for this communication mechanism to function. A telephone, for example, requires a sender, a receiver, and a signal to connect the two ports. They contain unique numerical addresses that allow the system to determine where the information is transmitted.

These ports are configured to guide traffic to the appropriate destinations; in other words, they are the assistants that instruct systems engaged in determining which service is being sought. Services vary from unencrypted HTTP web traffic on port 80 to FTP on port 21, which transports data and files between servers and clients.

There are 65,535 ports, although not all of them are used daily. On the other hand, the TLS/SSL port is one of the most regularly used ports and is almost certainly utilized daily. So, what port does TLS/SSL use? The TLS/SSL port is 443, HTTPS, and employs TLS/SSL certificates to safeguard port communications. HTTP is the unsecure protocol port (port 80).

What are the most often used TCP ports?

Managing TLS/SSL certificates necessitates a thorough understanding of security and network connectivity. Knowing some of the most frequent TCP (or transmission control protocol) ports may be important.

For your convenience, we’ve created a list of these popular TCP ports and their functions.

What Is the Purpose of Port 443?

As previously stated, TLS/SSL certificates secure port 443 communications. The primary role of TLS/SSL certificates is to protect information so that online traffic or cybercriminals cannot access it. This is why many businesses choose HTTPS over HTTP to safeguard their data from being exposed or compromised while it is being transferred and received.

SSL vs. TLS and HTTP vs. HTTPS: How do they function together?

Ssl vs. tls.

SSL certificates are a defunct word for what is now known as TLS certificates. They fundamentally provide identical security duties, yet many individuals continue to use the word SSL while others use TLS. It’s vital to keep in mind that they aren’t different, which is why certificates are commonly referred to as TLS/SSL, so that people understand that they are not different.

HTTP vs. HTTPS

HTTP and HTTPS are not two distinct protocols. Rather, HTTPS is a specialized form of HTTP that employs TLS/SSL certificates. HTTPS is thus simply a safer version of HTTP that is safer to use while transferring data.

How do they function together?

The default network will begin with HTTP. To protect your network, you must install a TLS/SSL certificate on the web server that you are using. After that, the certificate will confirm your organization’s identity in order to launch the HTTPS protocol. This ensures that data is safely sent from a web server to a web browser.

Why are SSL ports necessary?

You may be asking why your network server needs an SSL port over other ports and internet connection techniques. TLS/SSL certificates will be your most dependable ticket to secure data transport. While safety is paramount, there are a few additional factors to consider:

PCI compliance requires the use of HTTPS:

In order to accept any form of online payment, you must be PCI compliant . This will also protect both your data and the information of your customers.

HTTPS is faster than HTTP

If you have a TLS/SSL certificate-protected page that is HTTPS, your information will most likely load significantly faster than it would on an HTTP website.

With more businesses, consumers, and internet hackers utilizing the internet on a daily basis, it’s reasonable to assume that security is more important than ever. Using an SSL certificate port to secure your organization is one of the finest preventative actions you can do when it comes to cyber security.

Managing TLS/SSL Certificates

Keeping your apps safe frequently boils down to good TLS certificate management. The use of TLS/SSL certificates is a critical initial step. However, many businesses overlook the need to safeguard their systems against compromise and misuse.

50 Common Ports You Should Know

Port number is a 16-bit numerical value that ranges from 0 to 65535. Well-known port (0-1023), registered port (1024-49151), and dynamic port is three types of port number space. (49152-65535).

These ports can be opened and used by software applications and operating system services to send and receive data over networks (LAN or WAN) that employ certain protocols (eg TCP, UDP).

For example, we use 80 for HTTP-web-based plain-text surfing and 443 for HTTPS-web-based encrypted websites in our daily work.

To conclude, a port is a logical form to identify system activities or various network services used to create local or network-based communications.

What are the functions of ports?

When interacting over the Internet, TCP and UDP protocols make connections, recompile data packages after the transfer, and then deliver them to applications on the recipient’s device. For this handover to work, the operating system must install and open the gateway for the transfer. Each door has a unique code number. After transmission, the receiving system uses the port number to determine where the data should be sent. The port numbers of the sender and receiver are always included in the data packet.

Ports are assigned sequential numbers from 0 to 65535. Some of these codes are standardized, meaning they are assigned to certain uses. Since code numbers are universally recognized and permanently assigned, these standard ports are also known as well-known ports. Registered ports are those that organizations or software developers have registered for their applications. Registration is handled by the Internet Assigned Numbers Authority (IANA). A diverse selection of dynamically assigned port numbers is also available. For example, when viewing websites, browsers use these ports. After that, the phone number is free again.

Why is it important to know these ports?

Any security researcher, bug bounty hunter, or anyone working with service configuration would benefit from this. Knowing how to do more thorough scans such as version detection or known vulnerabilities for ancient services that are still operating in the infrastructure, especially when using tools like Nmap, is handy when getting to know these protocols and services. 

The most 50 significant ports are listed here:

The following are some of the most common service names, transport protocol names, and port numbers used to differentiate between specific services that employ TCP, UDP, DCCP, and SCTP.

CBP Releases January 2024 Monthly Update

WASHINGTON — U.S. Customs and Border Protection (CBP) released operational statistics today for January 2024. Migrant encounters along the southwest border were significantly lower than experienced in December. CBP monthly reporting can be viewed on CBP’s Stats and Summaries webpage .

“As a result of seasonal trends, as well as enhanced enforcement efforts by the men and women of CBP and our international partners, southwest border encounters between ports of entry dropped by 50% in January. We continue to experience serious challenges along our border which surpass the capacity of the immigration system,” said Troy A. Miller, Senior Official Performing the Duties of the Commissioner. “CBP remains on the frontline in preventing fentanyl and other dangerous drugs from entering our country, enforcing our nation’s laws and interdicting 34% more fentanyl and 68% more cocaine than the previous month.”

CBP continues to work closely with U.S. Immigration and Customs Enforcement and U.S. Citizenship and Immigration Services to quickly process individuals encountered at the border and remove those who do not establish a legal basis to remain in the United States, utilizing consequences strengthened by the Circumvention of Lawful Pathways Rule.  Since May 12, 2023 to January 31, 2024, DHS has removed or returned over 520,000 individuals, the vast majority of whom crossed the southwest border, including more than 87,000 individual family members. The majority of all individuals encountered at the southwest border over the past three years have been removed, returned, or expelled.  Total removals and returns since mid-May exceed removals and returns in every full fiscal year since 2013.

Below are key operational statistics for CBP’s primary mission areas in January 2024. View all CBP statistics online. 

Ensuring Border Security and Managing Migration  

CBP has taken significant steps to surge personnel and resources to impacted areas and address challenges we have experienced across the southwest border. CBP continues to expeditiously process and remove individuals who do not have a legal basis to remain in the country. We are working together with our domestic and foreign partners to jointly limit disorderly migration across the region, offering lawful pathways and cutting out ruthless smugglers who continue to spread falsehoods and show disregard for the safety and well-being of vulnerable migrants. CBP is targeting and disrupting transnational criminal organizations and smugglers who take advantage of and profit from migrants.

In January 2024, the U.S. Border Patrol recorded 124,220 encounters between ports of entry along the southwest border, a decrease of 50% from December 2023.

CBP’s total encounters along the southwest border in January 2024 were 176,205, a decrease of 42% from December 2023. Total encounters include U.S. Border Patrol encounters between ports of entry, as well as individuals who presented themselves at ports of entry (including those with CBP One appointments, detailed further below).

Among CBP’s 176,205 total southwest border encounters in January 2024, encounters with single adults decreased by 35% compared to December 2023, encounters with unaccompanied children decreased by 37% , and encounters with family unit individuals decreased by 51% .

CBP continually analyzes and responds to changes in migration patterns, particularly irregular migration outside of legal pathways and border crossings. We work with our federal and international partners to combat human smuggling. The fact remains: the United States continues to enforce immigration law, and our borders are not open for those without a legal basis to enter the country. Migrants attempting to enter without authorization are subject to removal under Title 8 authorities.

CBP’s message for anyone who is thinking of attempting to circumvent lawful pathways to enter the United States is simple: don’t do it. When noncitizens cross the border unlawfully, they put their lives in peril. The U.S. Border Patrol has undertaken significant efforts in recent years to expand capacity to aid and rescue individuals in distress. To prevent the loss of life, CBP initiated a Missing Migrant Program in 2017 that locates noncitizens reported missing, rescues individuals in distress, and reunifies decedents’ remains with their families in the border region. In January, the U.S. Border Patrol conducted 245 rescues, totaling 1,611 rescues in FY 2024 .

CBP One™ App   

The CBP One™ mobile application remains a key component of DHS’s efforts to incentivize noncitizens to use lawful, safe, humane, and orderly pathways and disincentivize attempts to cross between ports of entry. In January, CBP processed approximately 45,000 individuals through appointments at ports of entry utilizing advanced information submitted in CBP One™

CBP One appointments accounted for 87% of noncitizens processed at ports of entry;  demonstrating that noncitizens will follow an orderly process when one is available. Since the appointment scheduling function in CBP One™ was introduced in January 2023 through the end of January 2024, 459,118 individuals have successfully scheduled appointments to present at ports of entry using CBP One™  instead of risking their lives in the hands of smugglers. The top nationalities who have been processed are Venezuelan, Mexican, and Haitian.

A percentage of daily available appointments are allocated to the earliest registered CBP One™ profiles, so noncitizens who have been trying to obtain appointments for the longest time will be prioritized. CBP is continually monitoring and evaluating the application to ensure its functionality and guard against bad actors. 

CHNV Parole Processes

Through the end of January 2024, over 357,000 Cubans, Haitians, Nicaraguans, and Venezuelans arrived lawfully and were granted parole under the parole processes. Specifically, over 75,000 Cubans,  144,000 Haitians,  64,000 Nicaraguans, and  92,000 Venezuelans were vetted and authorized for travel; and over  74,000 Cubans,  138,000 Haitians,  58,000 Nicaraguans, and  86,000 Venezuelans arrived lawfully and were granted parole.

As Safeguarding Communities by Interdicting Narcotics and Dangerous Drugs

As the largest law enforcement agency in the United States, CBP is uniquely positioned to detect, identify, and seize illicit drugs before they enter our communities. CBP’s combination of interdiction and intelligence capabilities, complemented by its border search authorities, scientific services, non-intrusive inspection equipment, and canine detection teams, places it at the forefront of the U.S. government’s efforts to combat illicit fentanyl and other dangerous drugs.

CBP continues to conduct operations, including Operation Apollo, which target the smuggling of illicit fentanyl and other dangerous drugs. These operations leverage intelligence and investigative information to target drug traffickers’ supply chains and interdict items required in the production of illicit fentanyl, including precursor chemicals, pill presses and parts, movement of finished product, and illicit proceeds.

Nationwide in January, fentanyl seizures increased 34% and cocaine seizures increased 68% from December to January.

To date in FY 2024 through January, CBP has seized 7,000 pounds of fentanyl. CBP has stopped more fentanyl in the last two years than in the previous five years combined, and we continue to optimize our intelligence and field operations to stop these deadly substances from reaching American communities. 

Additional CBP drug seizure statistics can be found on the Drug Seizure Statistics webpage .

Facilitating Lawful Trade and Travel and Promoting Economic Security 

 As international travel continues to increase, CBP is leveraging technology to streamline efficiency and increase security at air and land ports of entry. Travelers are encouraged to utilize CBP’s mobile apps to enhance their travel experience, including the Global Entry Mobile Application and Mobile Passport Control , as well as new Global Entry Touchless Portals at nearly all international airports across the United States, which protect passenger privacy and expedite arrival processing by eliminating paper receipts.

Travelers arriving by air into the United States increased 14% from January 2023 to January 2024, and pedestrians arriving by land at ports of entry increased 2.6% over the same period.  

CBP works diligently with the trade community and port operators to ensure that merchandise is cleared as efficiently as possible and to strengthen international supply chains and improve border security. In January 2024, CBP processed more than 2.7 million entry summaries valued at more than $267 billion , identifying estimated duties of nearly $7 billion to be collected by the U.S. government. In January, trade via the ocean environment accounted for 44% of the total import value, followed by air, truck, and rail.

Consumers are encouraged to be alert to the dangers of counterfeit goods especially when shopping online as they support criminal activity, hurt American businesses, and often have materials or ingredients that can pose serious health and safety risks. Every year CBP seizes millions of counterfeit products worth billions of dollars had they been genuine. In January, CBP seized 1,814 shipments that contained counterfeit goods valued at more than $718 million . More information about CBP’s intellectual property rights enforcement is available at https://www.cbp.gov/trade .

Protecting Consumers and Eradicating Forced Labor from Supply Chains     

CBP continues to lead U.S. government efforts to eliminate goods from the supply chain made with forced labor from the Xinjiang Uyghur Autonomous Region of China. In January, CBP stopped 424 shipments valued at more than $236 million for further examination based on the suspected use of forced labor.

Intellectual property rights violations continue to put America’s innovation economy at risk. Counterfeit and pirated goods threaten the competitiveness of U.S. businesses, the livelihoods of American workers, and the health and safety of consumers.

Defending our Nation’s Agricultural System     

Through targeting, detection, and interception, CBP agriculture specialists work to prevent threats from entering the United States.  

CBP issued 6,248 emergency action notifications for restricted and prohibited plant and animal products entering the United States in January 2024. CBP conducted 102,987 positive passenger inspections and issued 898 civil penalties and/or violations to the traveling public for failing to declare prohibited agriculture items.
