# Zero-Trust Security Model

**Canonical:** https://apis.io/providers/zero-trust-security-model/  
**Website:** https://www.cloudflare.com/learning/security/glossary/what-is-zero-trust/  
**APIs profiled:** 5

The Zero Trust security model is a strategic cybersecurity approach that eliminates implicit trust and requires continuous verification of every user, device, workload, and request attempting to access resources, regardless of network location. It is rooted in NIST SP 800-207, formalized for federal agencies by the CISA Zero Trust Maturity Model and the DoD Zero Trust Reference Architecture, and operationalized by NSA, NCSC, and industry guidance. This topic indexes the canonical specifications, guidance documents, advocacy organizations, and reference data schemas that describe the Zero Trust security model and its pillars (Identity, Devices, Networks, Applications & Workloads, Data, Visibility & Analytics, Automation & Orchestration).
