SSL Security Test
Deep analysis of your server's SSL/TLS configuration with a security grade. Tests protocols, cipher suites, certificate chain, and HSTS.
Get an SSL Labs-style letter grade (A+ through F) for any domain. We test protocol support, cipher strength, key exchange, vulnerability exposure, and certificate chain health — all in one scan.

What does this SSL security test check?
This tool performs a deep analysis of your server's SSL/TLS configuration, similar to Qualys SSL Labs. It tests which TLS protocol versions are supported (TLS 1.0 through 1.3), enumerates all accepted cipher suites, validates the certificate chain, checks HSTS headers, and computes a security grade from A+ (best) to F (worst).
How is the grade calculated?
The grade uses the SSL Labs methodology: Protocol Support (30%), Key Exchange strength (30%), and Cipher Strength (40%). Certain conditions force a lower grade regardless of score — for example, supporting TLS 1.0 caps the grade at B, while an expired certificate always results in F.
