Every agent in Muster gets a risk score from 0 to 100, calculated automatically from its attributes. The score determines the risk level shown in the dashboard.

Discrepancies

If an agent is registered as “no PII” but Muster’s discovery scanners detect PII-related patterns in its code or API calls, the agent is flagged with a discrepancy. Discrepant agents appear in the inventory with a warning badge and are prioritised in the Health Heatmap.

Risk score vs risk level

The score (0–100) is the raw value. The level (Critical/High/Medium/Low) is the band it falls into. Use the score for sorting and trend analysis; use the level for at-a-glance status.
