implementing-epss-score-for-vulnerability-prioritization

separate

Queries FIRST's Exploit Prediction Scoring System (EPSS) API to fetch exploitation-probability and percentile scores for CVEs, then uses those scores to prioritize vulnerability remediation. Use when triaging or ranking a vulnerability backlog by real-world 30-day exploitation likelihood rather than CVSS severity alone.

When to use

• When deploying or configuring implementing epss score for vulnerability prioritization capabilities in your environment
• When establishing security controls aligned to compliance requirements
• When building or improving security architecture for this domain
• When conducting security assessments that require this implementation

When not to use

• measuring vulnerability severity alone
• using CVSS severity as the sole prioritization metric
