🔀 Domain Security Comparison

Compare the security posture of two domains side by side — SSL certificates, security headers, and overall grade.

How Domain Security Comparison Works

This tool fetches the SSL certificate and HTTP security headers of two websites simultaneously, then presents them side by side so you can compare their security posture at a glance.

What We Check

  • SSL Certificate — validity, issuer, and expiration
  • Security Headers — 7 critical HTTP headers that protect against common attacks
  • Overall Grade — A to F rating based on header coverage

When to Use This

  • Comparing your site against a competitor
  • Before and after security hardening
  • Evaluating third-party services or vendors
  • Security audits and compliance checks
