‼️ On Monday, March 17th 2025, EPSS v4 will be released and replace the current version (v3).
❓ What does this mean?
The model is being updated and expanded to include more data sources and is more accurate than v3. The Coverage/Efficiency Curve (Precision/Recall) indicates better performance at every threshold and therefore you get better risk management at all risk appetites.
➡️ Do I have to do anything to switch from v3 to v4?
No. The location of the data will remain the same. The API at FIRST will switch over to serving v4 scores automatically on Monday morning, and the CSV will remain accessible from Cyentia Institute, though there will be a redirect to Empirical Security.
⭐ Why is the model updating?
The v4 model is trained on more recent exploitation data. The v3 model was also experiencing degradation in accuracy, which is normal for models over time as reality shifts.
🎁 What's new in v4?
👾 Additional exploitation data sources, including Shodan, HackerOne Hacktivity, endpoint detections, and malware
🪄 More recent exploitation training data than v3
🎯 Recalibrating features (i.e. Twitter being dropped, CVE.org being added as a backup to NVD, and CVSS score changes over time)
