Which technology primarily supports the Zero Trust approach in FortiSASE?

Zero Trust Network Access (ZTNA) is fundamentally designed to enable businesses to adopt a Zero Trust security model, which is integral to FortiSASE technology. The Zero Trust approach operates under the principle of "never trust, always verify," meaning that no user or device, whether inside or outside the network, is trusted by default. Instead, every access request is subjected to strict verification and continuous assessment.

ZTNA solutions enforce access controls based on user identity, context, and device posture, ensuring that only authorized users have access to specific applications and data. This significantly enhances security, especially in environments where remote work and cloud services are prevalent. FortiSASE integrates ZTNA to facilitate secure connectivity and application access without the need for traditional VPNs, making it a cornerstone of its security architecture.

In contrast, the other options, while relevant to network security, do not encapsulate the Zero Trust philosophy in the same way. VPNs, for example, provide secure channels for data but do not inherently verify user identity or device security after a connection is established. Next-generation firewalls (NGFW) enhance threat detection and response but also do not embody the principles of Zero Trust as comprehensively as ZTNA. Legacy network systems often rely on
