On March 17, 2025, the Forum of Incident Response and Security Teams (FIRST) released EPSS Version 4, a major leap forward in EPSS score vulnerability management. Unlike traditional models like CVSS that focus on theoretical severity, the EPSS score framework predicts which issues are likely to be exploited in the next 30 days. This helps organizations focus on real threats instead of wasting time on low-impact issues.
What’s New in EPSS Version 4?
The fourth version of EPSS brings sharper exploit insights, better data, and smarter prioritization. Jay Jacobs (Empirical Security) and Qasim Arshad shared updates that take EPSS v4 to the next level. As a result, teams now get clearer, faster signals on what attackers may target next.
Expanded Exploit Intelligence: EPSS now monitors real-world exploitation data for over 10,000 vulnerabilities every month—boosting the precision of EPSS score vulnerability predictions.
Malware & Endpoint Integration: EPSS v4 adds telemetry from endpoint detection systems and malware analysis tools, allowing security teams to spot EPSS score patterns faster.
Broader Threat Context: It also analyzes hundreds of security sources—RSS feeds, blogs, forums—to provide better situational awareness of emerging threats.
Improved Categorization: EPSS now groups weaknesses under the top 22 CWE types and excludes REJECTED CVEs, eliminating unnecessary noise in EPSS score assessments.
Proven Efficiency Over CVSS: Independent studies show EPSS v4 reduces remediation efforts by more than 8x compared to CVSS-based approaches, especially when prioritizing high-volume vulnerabilities.

Xygeni + EPSS v4: Fix the Vulnerabilities That Matter Most
Xygeni integrates EPSS vulnerability score directly into its vulnerability prioritization funnels. So instead of chasing every high CVSS score, teams focus on what really matters.
With exploitability, reachability, and business context combined, priorities become clear. As a result, EPSS score vulnerabilities that pose real risk get fixed faster.
Xygeni’s Full-Stack Prioritization Model Includes:
- EPSS Exploitability Scoring: Uses EPSS v4 to identify likely attack vectors within the next 30 days.
- Runtime Reachability: Confirms whether the vulnerable code actually runs in production.
- CVSS Severity Insight: Adds broader context about potential system impact.
- Business Context: Filters findings based on criticality, system sensitivity, and operational risk.
Together with Xygeni’s contextual analysis, these insights surface directly inside CI/CD pipelines and risk dashboards. Therefore, vulnerability prioritization becomes automatic, real-time, and aligned with how software gets built and deployed.
Prioritization Funnels: Your Command Center for EPSS Score Vulnerability Management
To begin with, Xygeni’s Prioritization Funnels apply layered filters across all findings—SAST, SCA, CI/CD configs, IaC templates, and secrets. As a result, teams can define custom or prebuilt rules to automatically surface the vulnerabilities that truly demand attention.
Furthermore, built-in funnels for each environment (SAST, IaC, CI/CD) dramatically reduce time spent triaging issues and, at the same time, help cut through alert fatigue. Consequently, teams experience fewer distractions, better risk coverage, and faster remediation.
Final Thoughts
Without a doubt, EPSS Version 4 sets a new benchmark for exploitability-driven prioritization. Moreover, when combined with Xygeni’s end-to-end visibility and automation, it unlocks a more intelligent, focused way to manage vulnerabilities.
The volume alone of threats can be overwhelming. However, focus makes all the difference. That’s why Xygeni’s integration with EPSS v4 ensures EPSS score vulnerability prioritization aligns perfectly with how modern teams build, test, and ship code—so they fix the right issues, right now.
