Zero trust replaces network location as a trust signal with continuous verification of identity, device compliance, and session behavior.
For remote employees, this means endpoint security policies are enforced consistently regardless of where they connect from. A device missing a required patch, lacking an EDR agent, or connecting from an unusual location is blocked before it can access company resources.
The Cybersecurity and Infrastructure Security Agency Zero Trust Maturity Model defines implementation across five pillars: Identity, Devices, Networks, Applications & Workloads, and Data. NIST SP 800-207 provides the core architectural guidance for building Zero Trust environments that enforce these continuous verification principles.
