The HTTP security headers a browser actually enforces — HTTPS enforcement, HSTS, Content-Security-Policy, clickjacking protection, and cookie flag hygiene (Secure/HttpOnly/SameSite) — read from your site's real response headers. A header-hygiene check, not a penetration test.
Checks the headers your server actually sends, on every crawled page.
Clickjacking exposure checked correctly — only flagged when neither X-Frame-Options nor a CSP frame-ancestors directive is present.
Every missing header or cookie flag cited as evidence, with a concrete header to add.
Security Headers Audit automatically crawls your website using a real headless browser to inspect: Checks the headers your server actually sends, on every crawled page. Clickjacking exposure checked correctly — only flagged when neither X-Frame-Options nor a CSP frame-ancestors directive is present. Every missing header or cookie flag cited as evidence, with a concrete header to add.
Engineering leads, DevOps teams, SEO specialists, and product managers who need deterministic, evidence-backed inspection reports without generic AI hallucinations.
Our engine launches an isolated browser session, captures exact network requests, response headers, DOM snapshots, and console errors, and maps observable findings to actionable remediation steps.
The free tier audits up to 5 pages instantly (5 free scans/day). Comprehensive full-site reports with deep evidence citations are available for $3.99 per audit.
