Wrong claim
Why it feels true
Vendor marketing decks and network segmentation diagrams often label a single ZTNA proxy or isolated VLAN as a finished Zero Trust deployment.
Precise correction
NIST SP 800-207 (final 11 August 2020) defines Zero Trust Architecture around resource protection principles: network location never grants implicit trust, and every session requires dynamic authentication and least-privilege authorization before reaching a resource.
An identity-aware proxy, a ZTNA gateway, or a segmented avionics VLAN can serve as one Policy Enforcement Point (PEP) inside that architecture.
None of those products or components is the architecture itself, and none of them replaces an application-level policy decision governing which specific telemetry records contractor Dax Mercer may read or write.
