What are ZTNA tags used for in FortiGate?

ZTNA (Zero Trust Network Access) tags are an essential component within FortiGate’s architecture, particularly in defining access control policies. These tags are utilized to establish a dynamic and granular access control framework based on the security posture of the devices requesting access to the network. By using ZTNA tags, organizations can ensure that access permissions are tightly aligned with the security status of each device, effectively enforcing the zero trust model that requires verification for every access request, regardless of the source.

This approach enhances security by allowing only trusted devices that meet specific predefined criteria, such as compliance with security policies or desired configurations, to access particular resources or applications. Consequently, ZTNA tags contribute to reducing the attack surface and preventing unauthorized access, making them a pivotal aspect of FortiGate’s security strategy.

The other options, while potentially relevant to network management, do not accurately reflect the primary function and purpose of ZTNA tags within FortiGate's context. The focus on security posture and access control significantly underscores the importance of ZTNA tags in a modern security landscape.
