  • Cisco ASA Next-Generation Firewall Services

Known Affected Releases

9.2(1)

Description (partial)

Symptom:
Starting in version 9.2, CX has the ability to filter TLS/SSL connections without a full decryption policy. However, since the connections are not being decrypted, CX can't inject a deny page into the flow when a site is blocked. 
The current behavior is that the flow is immediately and silently dropped after the certificate exchange.

Conditions:
This is an enhancement request to improve the end user behavior for these types of connections.
