Security Headers Auditor

Audit critical HTTP headers with Security Headers Auditor and harden your web surface.

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.

Please solve the captcha first.
Security Headers Auditor highlights missing or weak security headers that can expose applications to common threats. Use it to validate CSP, HSTS, and related controls with clear output your team can act on immediately. Great for pre-launch checks and continuous hardening.
