If you follow Cyentia Institute’s Jay Jacobs via social media you may FIRST ;-) have learned about the Exploit Prediction Scoring System (EPSS) from him, as I did. I quickly learned that FIRST offers an API for the EPSS Model, which immediately piqued my interest. Per FIRST, EPSS provides a fundamentally new capability for efficient, data-driven vulnerability management. While EPSS predicts the probability (threat) of a specific vulnerability being exploited, it can scale to estimate the threat for multiple vulnerabilities on a server, a subnet, mobile device, or at an enterprise level (Jacobs, 2022).
