HTTP Header Checker & Security Audit
Inspect HTTP response headers, status codes, redirect chains, and security headers like HSTS, CSP, and X-Frame-Options.
About HTTP Header Checker & Security Audit
HTTP response headers contain essential metadata regarding caching policies, server engines, and web security. This tool issues a live HTTP request to your URL, logs all returned response headers, and audits whether essential security defenses like Content-Security-Policy and Strict-Transport-Security are active.
How to Use This Tool
- Enter the target URL (e.g. 'https://example.com').
- Click 'Inspect HTTP Headers'.
- Review the HTTP status code (200, 301, 302, 404, etc.) and complete header dictionary.
- Check the Security Scorecard to see which hardening headers are present or missing.
