Abstract
Systems and methods for performing zero-trust network access (ZTNA) secure traffic forwarding are provided. In one example, as part of setting up a transmission control protocol (TCP) forward access proxy (TFAP) tunnel, between a target service and an endpoint security agent of an endpoint device through which an application running on the endpoint device can interact with the target service, a secure connection is established between the endpoint security agent and a ZTNA access proxy (AP). Based on an encryption status of traffic transmitted from the application to the target service: (i) protection against eavesdropping by a man-in-the-middle attacker is provided by using the secure connection to encrypt one or more critical messages of the traffic between the endpoint security agent and the ZTNA AP; and (ii) the endpoint security agent abstains from switching to bypassing mode through the TFAP tunnel until after the one or more critical messages of the traffic have been exchanged.
