Divining Risk: Deciphering Signals From Vulnerability Scores

Vulnerability scores promise clarity, but too often just add to the noise. In this report, we analyze signals from over 270,000 CVEs to reveal what CVSS, EPSS, and SSVC actually tell us — and what they don’t. Discover what these systems get right, where they fall short, and how to turn that insight into smarter prioritization.

runZero Hour Ep. 18: Unpacking vulnerability scoring systems with EPSS expert Jay Jacobs

This special edition of runZero Hour, features vulnerability scoring expert Jay Jacobs from Empirical Security.

Jay will be joined by Tod Beardsley and Rob King for an insightful session exploring how scoring systems like CVSS, EPSS, and SSVC signal risk — and how to read between the lines to make smarter, faster decisions.

You’ll learn:

What each scoring system was built to do — and why that matters
Where scoring models diverge
How to use context to prioritize more effectively
Key takeaways from our new paper: “Divining Risk: Deciphering Signals From Vulnerability Scores”

Meet Our Speakers
