Options:

Send a message encrypted with the system’s peer’s public key to verify that the peer can decrypt the message with the private key of the entity that is identified in the certificate.

Decrypt the certificate signature using the CA private key and check to make sure that the certificate hash matches what they received from the peer.

Ensure that the issuer and the subject match on the certificate of the peer.

Contact the CA by phone to determine how they validated the identity of the system during certificate enrollment of the peer that they are communicating with.
