    Overview

    NIST Zero Trust Architecture emphasizes dynamic policy decisions backed by continuous telemetry. QuantLayer implements this with identity-backed verification, staged enforcement, and immutable evidence so every decision is traceable.

    Component mapping

    Policy Engine (PE)

    Evaluates identity, posture, and context to score risk and return allow/deny decisions.

    Policy Administrator (PA)

    Orchestrates decisions into staged enforcement, simulations, and guardrails across IT/OT/IoT.

    Policy Enforcement Point (PEP)

    Applies segmentation, quarantine, access controls, and runtime remediation near assets.

    Telemetry

    Feeds posture, patch, integrity, and behavioral signals into the PE for live scoring.

    Access decision flow

    • Subject requests access to a resource.
    • QuantLayer verifies identity and posture continuously.
    • Policy evaluation computes risk and a decision.
    • Enforcement point applies allow/deny/step-up/isolate.
    • Immutable audit evidence is recorded for the outcome.

    Continuous diagnostics

    Telemetry is treated as decision input, not passive logging—integrity drift, patch gaps, anomalous access, and policy violations update trust in near-real time.

    Audit evidence

    For audit and incident response, QuantLayer captures signals evaluated, policy version, decision, enforcement action, operator identity, and outcome verification.

    Result
    You can prove what was verified, what was enforced, and why.
