Check Security Headers

Check security headers and see which protections a site exposes.

How it works?

Security headers are HTTP response headers that a website's server sends to the browser. These headers tell the browser how to behave when handling the content of your site.

A high security score indicates that your website has implemented modern defensive measures against common attacks like Cross-Site Scripting (XSS) and Clickjacking, which improves both user safety and search engine trust.

Check website security headers and review missing protections like CSP, HSTS, and frame controls.

For browser follow-up on security headers, use SSL certificate checker and password entropy calculator.
