What is the purpose of configuring ZTNA tags on FortiGate?

Configuring ZTNA (Zero Trust Network Access) tags on FortiGate is crucial for defining access control policies based on the security posture of devices. When ZTNA tags are used, they enable the FortiGate infrastructure to classify devices and users according to predefined criteria, such as the compliance status of the device, the user's role, or the context of access requests. This classification facilitates the implementation of more granular access controls, allowing organizations to enforce policies that permit or restrict access to resources based on the security characteristics of the connecting device or user.

This approach aligns with the principles of the Zero Trust security model, which posits that trust should not be assumed, and access should be verified continuously. By using ZTNA tags, administrators can ensure that only those devices that meet specific security requirements are granted access to sensitive applications or data.

The focus on device security posture is essential in today’s threat landscape, where a compromised device can lead to significant vulnerabilities. With ZTNA tags, organizations can enforce a policy that allows access only if the device is compliant with security standards, mitigating risks associated with unauthorized access or weak security protocols.
