SSL (often referring to TLS in modern use) is a security technology that encrypts data exchanged between a website and a visitor’s browser. When SSL/TLS is active, your website uses HTTPS instead of HTTP, which helps protect sensitive information such as login details, contact form submissions, and payment data from being intercepted. SSL/TLS also supports trust signals in browsers, as many will warn users when a site is not secure. Certificates must be installed correctly and renewed to maintain secure connections. For most websites, HTTPS is considered a baseline requirement for security and user confidence.
