The EPSS (Exploit Prediction Scoring System) score calculates the exploitability of a vulnerability. This score is established and maintained by FIRST and can therefore fluctuate from one day to the next depending on the organization's context. It complements the CVSS score for an even more refined vulnerability analysis. The score is expressed as a percentage, from 0% to 100%.
In the IKare solution, the vulnerability management screen highlights on a graph the distribution of the most critical vulnerabilities to address: those combining the highest CVSS scores and the highest EPSS percentages.
