We give remote financial support (via RDP) to various clients, colleagues and partners. Recently, we were required by a partner to use a VPN they setup in order to connect to their computer. We had a concerned due to the nature of VPN regarding traffic at our end (which was answered, see EE
question for detail).
We understand that when we connect to a partners computer using their VPN, their admin can view all the network traffic in our computer; besides the the traffic regarding our support to them, but also whatever internet navigation, or computers locally navigated to, etc. Our question now is, if possible, How to protect our core network traffic, (the non-partner-support traffic)?
