Every time you see a padlock in your browser, buy something online, or install a “SSL certificate” on your site, you’re relying on one of these two protocols. They’re spoken about as if they’re the same thing \u2014 people say “SSL” constantly \u2014 but technically, SSL has been dead for years<\/strong>, and what actually protects your connection today is TLS<\/strong>. So why does everyone still say SSL?<\/p>\n\n\n\n

This guide clears it up: the real difference between SSL and TLS, the full version history, why SSL was retired, what changed with TLS 1.3, and \u2014 the part that confuses most people \u2014 why the word “SSL” stuck around long after the protocol itself was gone.<\/p>\n\n\n\n

Quick answer:<\/strong> SSL (Secure Sockets Layer)<\/strong> was the original protocol for encrypting web traffic. TLS (Transport Layer Security)<\/strong> is its successor and what every secure connection uses today. All versions of SSL are deprecated and insecure<\/strong>; the current standards are TLS 1.2 and TLS 1.3<\/strong>. When someone says “SSL certificate” or “SSL connection” in 2026, they almost always mean TLS \u2014 the name simply stuck.<\/p>\n\n\n\n
