SSL Checker

This tool provides a self-assessment checklist for your website SSL/TLS configuration. It helps you evaluate whether you have HTTPS redirect, HSTS headers, valid certificates, TLS 1.2+, and no mixed content issues. You check each item and receive a security score.

SSL/TLS encrypts data between your visitors browser and your server, protecting sensitive information like passwords and credit card numbers. It also improves SEO rankings (Google prefers HTTPS sites), builds trust with visitors who see the padlock icon, and is required for many modern web features.

HTTP Strict Transport Security (HSTS) tells browsers to always use HTTPS when connecting to your site. This prevents downgrade attacks where an attacker forces a connection over unencrypted HTTP. Once a browser sees the HSTS header, it will automatically use HTTPS for all future visits.

Mixed content occurs when an HTTPS page loads resources (images, scripts, stylesheets) over HTTP. This creates a security vulnerability because those HTTP resources can be intercepted or modified by attackers. Modern browsers block or warn about mixed content to protect users.
