What is the purpose of configuring ZTNA policies on FortiGate?

Configuring Zero Trust Network Access (ZTNA) policies on FortiGate primarily serves to control how traffic is routed and inspected based on device posture. ZTNA operates on the principle of verifying the identity and security posture of a device before granting access to applications and resources, ensuring that only compliant and trusted devices can communicate with sensitive data.

This approach minimizes security risks by providing access based solely on the current state and integrity of the device rather than its location or traditional network boundaries. Therefore, the main goal of ZTNA policies is to enforce strict access control measures depending on various factors such as user identity, device health, and security policies, significantly enhancing overall security.

In contrast, limiting user access to specific websites pertains more to web filtering techniques rather than the broad traffic management and inspection goals of ZTNA. VPN capabilities focus on secure connections between devices and networks, which does not specifically relate to the principles of Zero Trust. Enhancing internet speed is generally outside the purview of ZTNA configurations, which are aimed more at security and access control than performance improvements.
