The security posture score gives you a single number (0-100) that reflects how well your organization governs its AI agent ecosystem. It is separate from the EU AI Act compliance readiness score — this score focuses on operational security, not regulatory compliance.

​
Score Dimensions

The score is calculated across 6 equally weighted dimensions:
DimensionWhat It MeasuresMax Points
Agent OwnershipPercentage of agents with at least one assigned owner16.7
Expiry CoveragePercentage of agents with an expiry date set16.7
Access ReviewsPercentage of agents with up-to-date reviews (not overdue)16.7
Quarantine HygieneNo unreviewed quarantined agents older than 7 days16.7
Kill Switch ReadinessAll high-risk agents have kill switch tested in the last 30 days16.7
Risk ClassificationPercentage of agents with a confirmed risk classification16.7

Security Posture vs Compliance Readiness

Both scores are complementary. A high security posture score means your agents are well-governed day-to-day. A high compliance readiness score means you can demonstrate regulatory compliance.

​
Improving Your Score

Each dimension has clear, actionable steps:
  1. Agent Ownership — Assign owners to all agents using ABAC.
  2. Expiry Coverage — Set expiry dates via Agent Lifecycle.
  3. Access Reviews — Configure review schedules and complete overdue reviews.
  4. Quarantine Hygiene — Review and resolve quarantined agents within 7 days.
  5. Kill Switch Readiness — Test the kill switch on high-risk agents periodically.
  6. Risk Classification — Classify all agents using Risk Classification.
