TLS Certificates vs. SSL Certificates: What’s the difference?

Home » Products » Security » TLS Certificates vs. SSL Certificates: What’s the difference?

Secure Sockets Layer (SSL) is an older security protocol that’s been replaced by Transport Layer Security (TLS), but the term “SSL” is still widely used. The main difference between SSL and TLS lies in their encryption methods and security features, with TLS being the more secure, updated version.

Many website owners get confused as they do not understand TLS certificate and SSL certificate, and some even use them interchangeably.

This guide breaks it all down and will help you understand TLS certificate vs. SSL certificate.

What is SSL?

SSL is a cryptographic protocol developed in the mid-90s to secure communications between a client (browser) and a server. SSL was the first widely adopted protocol that allowed websites to encrypt data like credit card details, passwords, and other sensitive information, preventing unauthorized access.

Initially, SSL was highly successful at making the internet a safer place, but as technology advanced, vulnerabilities in SSL were discovered. This led to the development of its successor, TLS, which fixed many of these issues. While SSL has since become outdated and insecure, the term is still frequently used in the industry, often mistakenly referring to the more secure TLS.

What is TLS?

TLS is the protocol that replaced SSL. Introduced in 1999, TLS offers stronger encryption, improved security, and more efficient data transmission. TLS also provides better protection against modern cyber threats like man-in-the-middle attacks and tampering, which SSL couldn’t fully mitigate.

There have been several versions of TLS, and TLS 1.3 is the latest and most secure version. Unlike SSL, TLS encrypts not only the communication itself but also adds layers of security to the handshake (the process by which the client and server establish a secure connection). This provides a faster and more secure browsing experience, which is why most modern websites now use TLS over SSL.

TLS Certificate vs. SSL Certificate

Aspect	TLS Certificate	SSL Certificate
Definition	A digital certificate that secures online communications.	An older term still used for TLS certificates.
Purpose	Authenticates the identity of your website. Establishes an encrypted connection between the server and users’ browsers.	Authenticates the identity of your website. Establishes an encrypted connection between the server and users’ browsers.
Legacy	Introduced as an upgrade to SSL.	The first widely adopted protocol for securing websites.
Common Usage	Often referred to as SSL for familiarity.	Frequently used interchangeably with TLS.
Security Level	More secure and efficient than SSL.	Older and less secure.

Why is it Still SSL?

Even though TLS has replaced SSL, the term “SSL” continues to be commonly used for several reasons:

1.Brand Recognition:

SSL was the first widely adopted security protocol for websites, and over time, it became synonymous with website encryption. Even after TLS took over, companies and service providers continued using the term “SSL” because it had already become well-known. So, when you see “SSL certificates” for sale today, you’re actually getting a TLS certificate—the security standard used today.

2.Ease of Communication:

For simplicity, many people continue using the term “SSL” because it’s more familiar to the average person, even though they’re technically referring to TLS. Over time, SSL has become shorthand for website security, regardless of the underlying protocol.

3.Legacy Systems:

Some older systems and software still support SSL, though this is increasingly rare. When people refer to TLS over SSL, they are generally talking about upgrading older systems to TLS while retaining the familiar terminology.

If you want to make sure your server is using the latest version of TLS, it’s a good idea to reach out to your web hosting provider for assistance or have a systems administrator configure the settings for you.

Frequently Asked Questions (FAQs)

1.Does TLS certificate require SSL certificate?

TLS is an updated version of the SSL certificate. All websites require a TLS/SSL certificate to encrypt and secure private data.

2.How do I know if my certificate is SSL or TLS?

If your website’s URL begins with HTTPS, that means your website has an SSL/TLS certificate. The ‘S’ in HTTPS indicates that the site is encrypted with an SSL/TLS certificate.
