EPSS vs. CVSS: What’s the Best Approach to Vulnerability Prioritization?

Many businesses rely on the Common Vulnerability Scoring System (CVSS) to assess the severity of vulnerabilities for prioritization. While these scores provide some insight into the potential impact of a vulnerability, they don’t factor in real-world threat data, such as the likelihood of exploitation.
