Zero Trust
A security model that trusts no user or device by default and verifies every access request, regardless of network location.
Zero trust replaces the old assumption that everything inside the corporate network is safe. Its guiding idea is never trust, always verify: every request to access a resource is authenticated, authorized, and continuously validated.
It relies on strong identity, device health checks, least privilege, and micro-segmentation, and it suits modern environments where users, devices, and services are spread across cloud and remote work.
