Limitations of Raw Counts
Total open vulns provides minimal decision signal—focus on exploitable paths affecting crown assets. This is a key metric in our [Security Maturity Model](/resources/blog/maturity-model-blog).
Exposure Half-Life
Measure time for 50% of newly discovered exploitable vulnerabilities to be remediated; track trend.
Exploitability Weighting
Combine EPSS, KEV catalog presence, asset sensitivity, & network exposure to prioritize.
Workflow Automation
Auto-create remediation epics with dependency graph context; integrate change windows & rollback plans.
Metrics
Exposure half-life, KEV item SLA adherence %, mean validation failure rate, remediation throughput (items/week).
Sources & Further Reading
CISA KEV Catalog.
EPSS (Exploit Prediction Scoring System).
NIST NVD (reference metadata).
Key Takeaways
Exposure half-life trending down = real risk reduction narrative.
