Hi, I´m getting some trouble trying to block ultrasurf. First i blocked it with App-ID and everything was ok, until some users of the internal network downloaded a new version to avoid URL-filtering.
Summary of log
NAT Port: 443
IP protocol: tcp
I can´t block SSL or Unknown category because we have an active GlobalProtect VPN, our exchange server and our DVR´s share the same category.
The traffic is detected as Suspicious TLS Evasion found, is using the same ID (threatid eq 14978) our exchange Active Sync server is using and we can´t lose that service. Is there any other way of block it using palo alto? I was thinking in using QoS but that would affect our GlobalProtect users, they often need to transfer big files to the internal network.
