Probe Security Headers

Check HTTP security headers across your web properties to identify missing protections like CSP, HSTS, and X-Frame-Options.

Security headers are the first line of defense for web applications. Headers like Content-Security-Policy prevent XSS, Strict-Transport-Security enforces HTTPS, X-Frame-Options blocks clickjacking, and X-Content-Type-Options prevents MIME sniffing. Missing or misconfigured headers leave your application vulnerable to attacks that are trivially prevented by proper header configuration.

The probe_hosts skill sends HTTP requests to your targets and analyzes the response headers for security-relevant configurations. It checks for the presence and correctness of all critical security headers, flags missing headers that should be present, and identifies misconfigurations that weaken their effectiveness.

This is essential for any organization managing multiple web properties. A marketing site, a main application, API endpoints, and CDN-served assets may all have different header configurations. Probing them all at once gives you a unified view of your security header posture and ensures nothing is left unprotected.
