The total number of vulnerabilities continues to rise. If we had to rely on just CVSS for prioritizing those vulnerabilities, we have an enormous hard time to remediate all of them. In this talk, we’ll explore the critical gaps in CVSS-based prioritization and discuss why factors like exploitability, asset criticality, and real-time threat intellig…
