Not really. Techniques such as perimeter-based security and VPNs often revert to the outdated ‘castle-and-moat’ security model. In many cases, this approach is no longer adequate.

While Zero Trust itself focuses primarily on the need to continuously verify users, other concepts like Least Privilege and Role-Based Access Control (RBAC) emphasize restricting access to only the systems and data users truly need.
