Designing Useful Detection Engineering Metrics

Measure detection coverage and quality with metrics that support engineering priorities instead of rewarding alert volume.

Measure Coverage With Context

Relate detections to prioritized techniques, critical assets, and available telemetry. A coverage percentage without business context creates false confidence.

Track Quality Over Quantity

Review false-positive causes, investigation usefulness, and time to improve faulty rules. Quality measures encourage engineering work that analysts can trust.

Use Metrics to Choose Work

A metric is valuable when it changes the backlog, investment, or control design. Retire dashboards that do not lead to a recurring decision.

Next Steps

Use this guidance as a starting point, assign clear ownership, and validate the approach against your organization’s systems, risks, and operating constraints.
