Settings to Control Traffic that is not Decrypted

You can use the No Decryption tab to enable settings to block traffic that is matched to a decryption policy configured with the No Decrypt action (PoliciesDecryptionAction). Use these options to control server certificates for the session, though the firewall does not decrypt and inspect the session traffic.

No Decryption Tab Settings	Description
Block sessions with expired certificates	Terminate the SSL connection if the server certificate is expired. This prevents users from accepting expired certificates and continuing with an SSL session. Block sessions with expired certificates to prevent access to potentially insecure sites.
Block sessions with untrusted issuers	Terminate the SSL session if the server certificate issuer is untrusted. Block sessions with untrusted issuers because an untrusted issuer may indicate a man-in-the-middle attack, a replay attack, or another attack.
