Zero trust

Zero trust is a cybersecurity framework built on the principle of "never trust, always verify." Unlike traditional perimeter-based security models that inherently trust users and devices inside the network, zero trust assumes that every user, device, application, and workload — whether internal or external — is a potential threat. Every access request must be rigorously authenticated, authorized, and continuously validated before being granted. This approach enforces least privilege access, ensuring entities receive only the minimum permissions necessary to perform their tasks.

A zero trust architecture leverages techniques such as micro-segmentation, granular access controls, and real-time monitoring to drastically reduce the attack surface and prevent lateral movement within a network, even in the event of a breach. Access decisions are dynamic and context-aware, continuously re-evaluated based on user identity, device posture, location, and behavioral attributes. By eliminating implicit trust and treating every interaction as potentially hostile, zero trust provides organizations with a robust, adaptive defense strategy designed to protect critical assets and sensitive data against increasingly sophisticated cyber threats.
