implementing-epss-score-for-vulnerability-prioritization
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.

# Implementing EPSS Score for Vulnerability Prioritization
## Overview
The Exploit Prediction Scoring System (EPSS) is a data-driven model developed by FIRST (Forum of Incident Response and Security Teams) that estimates the probability of a CVE being exploited in the wild within the next 30 days. EPSS produces scores from 0.0 to 1.0 (0% to 100%) using machine learning trained on real-world exploitation data. Unlike CVSS which measures severity, EPSS measures likelihood of exploitation, making it essential for risk-based vulnerability prioritization.
## 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
