How to use the HTTP Headers Analyzer

1

Enter a URL

Type the full URL you want to check, including https://. The tool fetches the HTTP response headers from that URL.

2

Run the analysis

Click Analyze. The tool returns all response headers and scores them for security, performance, and best practices.

3

Review the findings

Each header is flagged as Passed, Warning, or Failed with an explanation. Security headers like Content-Security-Policy and X-Frame-Options are checked.

4

Fix issues

Failed security headers indicate misconfigurations that could expose the site to attacks. Pass each item to your hosting provider or dev team to address.

Pro tips

  • Missing security headers are a common finding — they are easy to add and significantly improve security.
