HTTP security headers help protect websites from common attacks such as XSS, clickjacking, and data injection. This free security headers scanner allows you to scan any website and instantly check its HTTPS response headers, security score, and recommended improvements.

Scan Your Website Security Instantly

Website security is not just about SSL certificates. Proper HTTP security headers play a major role in protecting users and preventing common vulnerabilities. This security headers checker scans your website in seconds and analyzes public HTTPS response headers safely and securely.

Simply enter your website URL, and the tool will automatically follow redirects and read only publicly accessible headers.

Security Report Summary

After scanning a website, the tool generates a clear security report showing:

  1. Overall security grade (such as A+)
  2. Website URL and IP address
  3. Scan time
  4. Security score based on core headers

The grade is calculated using widely accepted industry best practices.

Core Security Headers Check

This tool checks for all essential HTTP security headers, including:

  5. Referrer-Policy
  6. Permissions-Policy

If these headers are present and properly configured, your website receives a higher security score.

Missing Headers Detection

The scanner clearly highlights whether any important security headers are missing. If all required headers are detected, the tool confirms that your website passes the advanced security header scan.

This makes it easy to identify potential weaknesses without manual inspection.
