Core Capability 5: Coverage Measurement and Reporting

This is the fifth and final core capability. Measurement quantifies prevention effectiveness, demonstrates ROI, and guides the next iteration of the prevention cycle.

PSPM quantifies prevention effectiveness through metrics, dashboards, and trend analysis:

Coverage metrics track prevention expansion over time. Percentage of accounts with organization policies. Percentage of repositories with IaC scanning. Number of preventive controls by layer and cloud. Services with secure defaults enabled.

Effectiveness metrics measure prevention impact. Risky actions blocked by organization policies. Alert volume reduction from CNAPP/CSPM. Issues prevented at each layer. Mean-time-to-remediate for runtime controls.

Efficiency metrics demonstrate resource optimization. Team capacity freed from remediation. Cost difference between prevention and remediation. Deployment velocity with prevention guardrails versus approval gates.

ROI calculations prove prevention value. Cost to deploy controls versus cost to remediate findings. Incidents avoided through prevention. Compliance evidence provided through preventive controls.

Trend analysis shows improvement over time. Prevention coverage expansion across quarters. Finding volume reduction as prevention deploys. Prevention posture maturity growth.

Multi-audience dashboards package metrics for different stakeholders. Executive dashboards show risk reduction and cost savings. Security team dashboards show coverage and gaps. Engineering team dashboards show issues caught before production.

Coverage measurement and reporting enable the Measure practice - quantifying prevention effectiveness and guiding iteration.
