Zero Trust Network Access (ZTNA) is the FortiSASE feature that ensures least-privileged user access

to all applications. ZTNA operates on the principle of "never trust, always verify," providing secure

access based on the identity of users and devices, regardless of their location.

Zero Trust Network Access (ZTNA):

ZTNA ensures that only authenticated and authorized users and devices can access applications.

It applies the principle of least privilege by granting access only to the resources required by the user,

minimizing the potential for unauthorized access.

Implementation:

ZTNA continuously verifies user and device trustworthiness and enforces granular access control

policies.

This approach enhances security by reducing the attack surface and limiting lateral movement within

the network.
