Zero Trust

Zero Trust is a security approach that avoids granting automatic trust from network location and requires explicit verification of identity, device, context and authorisation for each relevant access. It is not one product, a replacement name for VPN or an instruction to block everything. Implementation combines inventory, strong identity, least privilege, segmentation, device protection, policy, logging and response. Decisions rely on signals whose quality and availability need monitoring; missing data should not silently become trust. Adoption is usually incremental, beginning with higher-risk resources and journeys, with visible exceptions and recovery paths. Validation tests allowed and denied access, signal loss and revocation. Buying a product labelled Zero Trust does not prove that actual flows follow these principles.
