The rating follows the approach of the SSL Labs server rating guide (certificate, protocol, key exchange and cipher scores, with caps for known weaknesses), so results are close to — but not always identical with — SSL Labs. Only public servers on port 443 can be tested.

We can fix certificate, TLS and web server configuration issues, and keep certificates renewed so they never expire unexpectedly.
