TLS & Certificate

Protocol support, cipher strength and the certificate chain, evaluated the way a browser would.

Score90%
  • the server accepts 1 weak cipher suite(s): ECDHE-RSA-AES128-SHA256
NegotiatedTLSv1.3, TLS_AES_256_GCM_SHA384
Forward secrecyYes

Cipher suites probed

Each suite below was tested with its own TLS 1.2 handshake, restricted to exactly that cipher - "accepted" means the server completed a handshake using it, not merely that it's listed as a possibility.

Mail servers

Each mail port is probed with a full TLS handshake - STARTTLS on 25, 587, 143 and 110, implicit TLS on 465, 993 and 995 - to read the certificate actually bound to it. Only inbound SMTP on port 25 affects the grade.
