What is the goal of Zero Trust Network Access (ZTNA) in FortiSASE?

The goal of Zero Trust Network Access (ZTNA) in FortiSASE is to authenticate users and devices before granting access. This approach operates on the principle of "never trust, always verify," meaning that regardless of whether a user is inside or outside the network perimeter, they must be authenticated and authorized for access to resources. By implementing ZTNA, FortiSASE ensures that security is maintained even in highly dynamic environments where users may connect from various locations and using different devices.

In practical terms, this means that before a user can access a specific application or resource, their identity and device posture are verified. This helps in reducing vulnerabilities and protecting sensitive information from unauthorized access. By focusing on authentication rather than assuming that all internal traffic is safe, FortiSASE aligns with modern security challenges posed by remote work and cloud services, thereby enhancing overall security posture. This makes it a foundational strategy in implementing effective cybersecurity measures within Fortinet's SASE architecture.
