What is the role of ZTNA policies on FortiGate?

The role of Zero Trust Network Access (ZTNA) policies on FortiGate is to enforce security measures based on the device's posture and access requirements. This approach ensures that only authorized devices with compliant security statuses can access specific resources, thereby minimizing potential security risks. ZTNA operates on the principle of "never trust, always verify," meaning that every access request is evaluated based on various criteria, including the device's health, user identity, and contextual factors.

By implementing these policies, FortiGate can dynamically adjust access to resources, ensuring that only the appropriate devices and users can interact with critical data and applications. This capability is essential for maintaining a robust security posture in an increasingly complex threat landscape, where traditional perimeter defenses are no longer sufficient.

In contrast, defining network topology, managing bandwidth allocation, and disabling remote connections do not align with the primary goal of ZTNA policies, which focus on granular access control and security based on real-time assessments of device posture.
