Which FortiSASE feature ensures least-privileged user access to all applications?

The feature that ensures least-privileged user access to all applications is Zero Trust Network Access (ZTNA). ZTNA operates on the principle that no user or device should be trusted by default, regardless of their location within or outside the network perimeter. This approach verifies each access request based on the identity of the user, the device being used, and the context of the access request.

By implementing ZTNA, organizations can enforce strict access controls that limit users to only the resources and applications necessary for their role, thereby minimizing the risk of data breaches and unauthorized access. This level of granularity in access control is crucial for maintaining a secure environment where users are granted the least privilege necessary to perform their tasks.

In contrast, an application-level firewall primarily protects applications from external threats and does not inherently manage user access privileges. Network segmentation focuses on dividing a network into different segments to enhance security but does not specifically address individual user access levels. Data loss prevention strategies aim to protect sensitive data from being leaked but do not directly control user access to applications. Hence, ZTNA is the definitive solution for ensuring least-privileged access within secure application environments.
