Secure Headers Analyzer – Score Your Site’s HTTP Security Headers
Security headers are a critical layer of defense in web applications. They instruct the browser how to behave when interacting with your site—helping mitigate threats like clickjacking, MIME-type sniffing, cross-site scripting (XSS), and man-in-the-middle attacks. This Secure Headers Analyzer lets you paste a raw HTTP response (from tools like curl, Postman, or browser DevTools) and evaluates it against best practices.
The tool flags missing headers like Content-Security-Policy, Strict-Transport-Security, or X-Frame-Options and gives you a quick score of your site’s defensive posture. Ideal for developers, pentesters, and sysadmins doing audits or tuning reverse proxy configs. The analysis runs entirely client-side to keep things secure and fast.
