What does configuring FortiGate as a ZTNA access proxy enable?

Configuring FortiGate as a ZTNA (Zero Trust Network Access) access proxy primarily enables the management of access to protected resources based on device posture. This is a crucial feature of the Zero Trust security model, which assumes that threats can come from both outside and inside the network, and therefore, verifies every request as though it originates from an open network.

By evaluating the device posture, which includes checking the security status of the device, the operating system, and the presence of necessary security software, FortiGate can make informed decisions about granting or denying access to specific resources. This ensures that only authorized devices that meet the defined security criteria are allowed to access sensitive applications and data, thereby minimizing the risk of unauthorized access and potential data breaches.

The other choices do not align with the key functionality provided by FortiGate in ZTNA configurations. For instance, enhanced speed of data transfer and improved bandwidth are not inherent features related to the security posture assessment or access control provided by a ZTNA solution. Furthermore, ZTNA does not inherently reduce the need for user authentication; rather, it can make authentication more robust and context-aware.
