EPSS vs. CVSS: Exploit prediction could move the needle on software risk management

The report examines how the Exploit Prediction Scoring System (EPSS) complements and improves upon CVSS by providing data-driven, frequently updated probabilities of exploitation to help teams prioritize remediation amid alert fatigue and resource constraints. It highlights EPSS methodology, benefits, and limitations (e.g., reliance on CVE IDs and transparency concerns), summarizes critiques of CVSS’s lack of context, and notes improvements in EPSS v3.0, while discussing potential—though not guaranteed—gains for application and software supply chain security.
