Free Security Tool
Check if your website has a valid SSL certificate and is properly configured for HTTPS. Verify security headers, mixed content issues, and HSTS configuration in seconds.
This tool scans your website for SSL certificate validity, HTTPS enforcement, and related security headers. It checks whether your site redirects HTTP to HTTPS, whether all resources load over secure connections, and whether headers like HSTS, X-Frame-Options, and Content-Security-Policy are properly configured.
SSL certificates are a baseline requirement for any website. Google uses HTTPS as a ranking signal, browsers flag non-HTTPS sites as insecure, and visitors leave sites that trigger security warnings. Beyond rankings, a properly configured SSL setup protects your users from data interception and man-in-the-middle attacks.
