# Zero Trust Architecture

**Canonical:** https://apis.io/providers/zero-trust-architecture/  
**Website:** https://www.nist.gov/publications/zero-trust-architecture  
**APIs profiled:** 5

Zero Trust Architecture (ZTA) is a security framework defined by NIST SP 800-207 that requires all users and devices to be authenticated, authorized, and continuously validated before being granted access to applications and data, regardless of whether they are inside or outside the network perimeter. The architecture is built on the principle of "never trust, always verify," replacing implicit trust with explicit verification for every access request. ZTA leverages APIs, identity providers, policy engines, and continuous monitoring to enforce least-privilege access across enterprise resources.
