What is Zero Trust Architecture (ZTA)?

Zero Trust Architecture is a security model built on one rule: no user, device, or workload is trusted by default, whether it sits inside or outside the corporate network. Every request for access must be authenticated, authorized, and continuously evaluated before a connection is granted.

Formalized in NIST SP 800-207, ZTA replaces the older assumption that anything on the internal network is safe with per-request verification, least-privilege access, and fine-grained segmentation down to the individual resource where possible.

It is not a single product you buy. It is a set of design principles implemented through components such as a policy engine, policy enforcement points, identity providers, and continuous monitoring working together.

Zero Trust Architecture is best described as:
ZTA replaces the older security assumption that:
