What this tool checks

  • TLS 1.0, 1.1, 1.2 and 1.3 support
  • Cipher negotiated for each version
  • Grade from A to F

How to read the result

Ideally only TLS 1.2 and 1.3 are enabled. If our server cannot attempt an old version, it is reported as "could not be tested" rather than "not supported".
