Zero Trust Architecture (ZTA)

Formal Definition

A security framework requiring all users to be authenticated and authorized continuously, whether they are inside or outside the network.

Moves defense from a perimeter-based 'firewall' model to a continuous verification model to prevent lateral movement of attackers.

"Implementing Zero Trust required the organization to verify every device attempting to access the internal cloud environment."

Often marketed as a software package; Zero Trust is a strategic architectural methodology, not a single tool.
