Inspect HTTP response headers for any URL. Check security headers, caching policy, server info, and content type. Includes security analysis.
HTTP headers are metadata sent with every web request and response. They control caching, security policies, content encoding, and more. Security headers like Content-Security-Policy, Strict-Transport-Security, and X-Frame-Options protect against common attacks like XSS and clickjacking.
Run this check every minute, 24/7. Get alerted by email, SMS, or webhook when something breaks.
