HTTP Headers Checker

Analyze security headers of any website

About HTTP Headers Checker

Analyze the HTTP security headers of any website and get a security score with actionable recommendations.

How to use HTTP Headers Checker

  1. 1Enter the full URL of the website you want to analyze (e.g., https://example.com).
  2. 2Click 'Check headers' to fetch and analyze the response headers.
  3. 3Review the security score and the status of each recommended header (present or missing).
  4. 4Read the security recommendations for each missing header to understand the risks.
  5. 5Implement the suggested headers on your server to improve your security posture.

Tips

  • Some headers may not be visible due to CORS restrictions — for a complete audit, use server-side tools as well.
  • Prioritize Content-Security-Policy, Strict-Transport-Security, and X-Frame-Options — they cover the most common attacks.
  • Run this check after every deployment to catch accidental header regressions.
