SSL/TLS Security Scanner

Verify your SSL/TLS configuration, certificate validity, and encryption strength.

SSL/TLS is the encryption layer that protects data in transit between users and your server. Our scanner verifies certificate validity, checks for weak cipher suites, tests protocol versions, and ensures proper HTTPS enforcement including HSTS configuration.

What This Scanner Does

Checks SSL certificate validity and expiration, supported TLS protocol versions (TLS 1.2/1.3), cipher suite strength, certificate chain completeness, HSTS header presence, and whether HTTP properly redirects to HTTPS.

Why It Matters

Weak or misconfigured TLS allows attackers to intercept sensitive data through man-in-the-middle attacks. Expired certificates break user trust and trigger browser warnings. Search engines also penalize sites without valid HTTPS.

Common Findings

  • Certificate expiring within 30 days
  • TLS 1.0/1.1 still enabled (deprecated protocols)
  • Missing HSTS header or short max-age
  • HTTP not redirecting to HTTPS
