Whether you\u2019re browsing online, running an e-commerce store, or managing a web application, protecting sensitive data is critical. You may have encountered terms like <strong data-start=\"456\" data-end=\"463\">SSL<\/strong> and <strong data-start=\"468\" data-end=\"475\">TLS<\/strong>and wondered what sets them apart. Both are cryptographic protocols that secure data transmitted between clients and servers, but understanding their differences is crucial for website owners, developers, and IT teams.<\/p>\n<p data-start=\"698\" data-end=\"1039\">While <strong data-start=\"704\" data-end=\"734\">SSL (Secure Sockets Layer)<\/strong> laid the foundation for online encryption, <strong data-start=\"778\" data-end=\"812\">TLS (Transport Layer Security)<\/strong> is the modern protocol that provides stronger security, better performance, and improved encryption algorithms. Choosing the right protocol ensures your website is safe, protects user data, and maintains trust with visitors.<\/p>\n<h2 data-section-id=\"1teqs2u\" data-start=\"1266\" data-end=\"1285\"><span role=\"text\"><strong data-start=\"1269\" data-end=\"1285\"><a href=\"https:\/\/www.keycdn.com\/img\/support\/ssl-vs-tls.png\" target=\"_blank\" rel=\"noopener\"><img fetchpriority=\"high\" decoding=\"async\" class=\"aligncenter\" src=\"https:\/\/www.keycdn.com\/img\/support\/ssl-vs-tls.png\" alt=\"SSL vs TLS \" width=\"1536\" height=\"768\" \/><\/a><\/strong><\/span><\/h2>\n<h2 data-section-id=\"1teqs2u\" data-start=\"1266\" data-end=\"1285\"><a href=\"https:\/\/www.cloudflare.com\/learning\/ssl\/what-is-ssl\/\" rel=\"nofollow noopener\" target=\"_blank\"><span role=\"text\"><strong data-start=\"1269\" data-end=\"1285\">What is SSL?<\/strong><\/span><\/a><\/h2>\n<p data-start=\"1064\" data-end=\"1183\">SSL, or Secure Sockets Layer, was introduced in the 1990s to secure web communications.
