You want to know information about Transparent Proxy settings in SEP Mobile
Transparent Proxy was released on June 23 to alleviate an issue with an outdated policy.
Until the TECH doc gets published:
The recommendation is to always use Transparent Proxy unless the policy requires visibility into user-agent or their current legacy WSS policy requires an explicit proxy (mode).
Customer can review their WSS policy needs with WSS support to determine if they need to turn off Transparent Proxy mode.
