Zero Trust

    An architectural stance where no access is granted by network position; every request is authenticated, authorised and evaluated with signal.

    Updated

    Zero Trust replaces perimeter trust with per-request decisions based on identity, device state, application sensitivity and behavioural signal. It is a design principle, not a product you can buy. NIST SP 800-207 frames the baseline as verify explicitly, enforce least privilege, and assume breach.

    In practice the first steps are strong authentication for privileged roles, device compliance as an access condition, removal of standing privilege, and segmentation that assumes an internal foothold. AI agents strain these assumptions further and increasingly need unique credentials and continuous authorisation rather than a one-time handshake.
