California DMV uses convergepay for credit card processing. I just re-ran a check of that site on SSL Labs to check the certificate and security and the grade was a B (it was previously a C).
- There is no support for secure renegotiation
- This server does not support Forward Secrecy with the reference browsers.
- Server support weak cipher suites
- Certificate is not a extended Validation Cert.
Security have improved since my report in May of 2018.
