Vulnerability management has long leaned on vendor-assigned severity scores, but those numbers are theoretical abstractions. They describe how bad a flaw could be in a generic environment, not how dangerous it is for your particular systems, workloads, and exposure. That mismatch can lead teams to chase high-scoring but irrelevant issues while ignoring lower-scored vulnerabilities that are actively being exploited against similar setups.
The source argues that the real signal is exploit data: whether a vulnerability is being used in the wild, and whether it applies to the specific software versions, configurations, and network exposure an organization actually has. Shifting from score-based triage to exploit-driven prioritization means pulling in threat intelligence and mapping it against an accurate asset inventory. It is a more practical, context-aware approach, but it requires better data hygiene and a willingness to move beyond the familiar comfort of a single number.
