Free Security Headers Checker

Test a site’s security headers, review missing protections, and get a clearer starting point for CSP and header hardening work.

Use the free checker for point-in-time analysis, then move into hosted monitoring if you want alerts and header history.

Check Any Public Site

Run a quick check against public URLs to see what security headers are present, weak, or missing.

Understand the Grade

Review overall score, missing headers, and practical recommendations instead of reading raw responses by hand.

Move Into Monitoring

Use MetricPoints when you want to track changes over time and know when header configuration drifts in production.
