# Zero Trust Access Control

Zero Trust Access Control is a fundamental component of Zero Trust Network Access (ZTNA), which challenges the traditional notion of trust in network security. Unlike traditional perimeter-based security models that implicitly trust users and devices once they gain access to the network, Zero Trust Access Control operates on the principle of "never trust, always verify."

In a Zero Trust Access Control model, every access attempt is treated as potentially unauthorized until proven otherwise. This approach minimizes the risk of lateral movement and unauthorized access by enforcing strict authentication, authorization, and continuous monitoring mechanisms.

At GoodAccess, we embrace the Zero Trust philosophy and implement it through our comprehensive Zero Trust Access Control solution. It utilizes four key features:
