HTTP Security Observer

Check HTTP security headers and server info

About HTTP Security Observer

Our HTTP Security Observer fetches and analyzes HTTP response headers from any web server. It checks for critical security headers including Strict-Transport-Security (HSTS), Content-Security-Policy (CSP), X-Frame-Options, X-Content-Type-Options, and more. The tool also reports the server software and HTTP version, giving you a complete picture of your server's security posture.

2Click "Check" to fetch HTTP headers.
3Review all response headers and security configurations.
4Identify missing or misconfigured security headers.

Use Cases

•Audit HTTP security headers for compliance
•Verify HSTS is properly configured
•Check CSP policies for security weaknesses
•Monitor server information disclosure
