During the Symantec Endpoint Protection Mobile (SEPM) installation the VPN step message says "network activity may be monitored", does it mean that SEP Mobile is monitoring my activities?
No. The SEPM app provides protection against network threats without monitoring outgoing traffic from the device.
When SEPM detects a potential threat on the network the device is currently connected to it will automatically connect the SEPM VPN in order to mitigate this threat, while the threat persists Skycure is routing all outgoing traffic from the device to a VPN server, thereby keeping the communication secure.
Once the device disconnects from the specific threatening network, the VPN will be automatically disabled.
