Both SSL (Secure Socket Layer) and TLS (Transport Layer Security) are protocols designed to keep your internet communication safe from hackers and snoopers. According to Google Transparency Reports, over 90% of web traffic today is encrypted - and that’s thanks to these two technologies.
But are SSL and TLS the same thing?
Let’s break it down.
Similarities Between SSL and TLS
Both protocols aim for the same goal - secure data transmission. Here’s what they have in common:
SSL vs TLS: The Core Differences
The major distinction is that TLS is the successor to SSL - meaning it’s a newer, stronger, and more efficient version. They can’t directly work with each other because their inner workings differ.
Here’s how they stand apart:
TLS supports stronger cryptographic algorithms, making it far more secure than SSL.
The alert messages and record formats differ in both, meaning they handle data validation and error communication in unique ways.
Why TLS Has Replaced SSL
The latest version, TLS 1.3, has officially superseded SSL. It’s faster, safer, and eliminates outdated encryption methods that were vulnerable to attacks.
Modern browsers and servers no longer support SSL because it’s considered obsolete and insecure.
Why You Still Hear "SSL Certificates"
Even though websites advertise “SSL Certificates,” in reality, all modern SSL certificates are actually TLS certificates. The term “SSL” just stuck around because it’s familiar to users.
So when you install an “SSL certificate,” you’re really getting TLS encryption - the latest and most secure standard.
Final Thoughts
In today’s web environment, TLS is essential for both security and SEO. Browsers like Chrome and Firefox warn users when a site isn’t encrypted, which can harm your reputation and trust.
Keep your site safe - use a valid SSL/TLS certificate and stay updated with the latest versions.

Both protocols aim for the same goal - secure data transmission. Here’s what they have in common:
Data Encryption: They ensure that any data sent between your browser and the website remains private and unreadable to outsiders.
Authentication: Both verify that the website you’re communicating with is legitimate and not an attacker’s imitation.
Certificates: SSL and TLS require a valid digital certificate issued by a trusted Certificate Authority (CA), such as Entrust or DigiCert.

The major distinction is that TLS is the successor to SSL - meaning it’s a newer, stronger, and more efficient version. They can’t directly work with each other because their inner workings differ.Here’s how they stand apart:
1. Communication Flow
- SSL starts by setting up security immediately and then proceeds with secure communication.
- TLS begins with an insecure “hello” message before establishing encryption through a handshake process.
2. Encryption Strength
TLS supports stronger cryptographic algorithms, making it far more secure than SSL. 3. Alert & Record Protocols
