Zero Trust Decision Flow

• Collect signals (identity, device, network, workload).
• Compute risk and trust posture.
• Evaluate policy and produce a decision.
• Enforce the decision close to the asset.
• Record immutable evidence and verify outcomes.

• Authentication and verification outcomes.
• Integrity state and tamper indicators.
• Patch and vulnerability posture.
• Unexpected east-west movement attempts.

Risk scoring prioritizes what matters most using severity, criticality, and blast radius context.

Policies combine subject/resource/action/context to decide allow/deny/step-up/quarantine.

Enforcers apply segmentation and access controls; OT can use staged enforcement to avoid downtime.

Every decision includes the “why”: which signals and policy version produced the action.

• High-risk remote admin -> require step-up verification and notify SOC.
• Integrity failure -> quarantine device and open an incident ticket.
• New lateral connection path -> block and alert until validated.
