Zero Trust Network Access (ZTNA) is a category of technologies that provides secure access to applications and services. ZTNA allows “least privilege” access to specific applications and resources, and not the entire underlying network to any user with valid login keys, thus reducing the attack surface and preventing lateral movement of attacks from compromised accounts or devices. ZTNA builds upon the concept of “Zero Trust,” that asserts that organizations shouldn’t implicitly trust any entity, whether inside or outside the security perimeters, and instead must verify every user or device before granting them access to sensitive resources, ensuring data safety and integrity.
