Fixing More Vulnerabilities Is Not Cutting Breach Risk: Why Prioritisation Needs to Change

Many security teams are fixing more vulnerabilities than ever, yet their breach risk has barely moved. According to the source, Gartner's report on exposure prioritisation says fewer than 10% of vulnerabilities are exploited, yet most are treated as urgent. It also argues that CVSS scores alone do not predict actual exploitation or business impact. The result is effort spent on exposures attackers may never use, while higher-risk issues wait in the queue.

Gartner's framework rests on four elements: threat intelligence, asset context, exploitability modelling and security control validation. Each answers a different question about an exposure, and an exposure deserves urgent remediation only when all four answers point the same way. Gartner predicts that by 2028, organisations using all four will reduce breach likelihood by at least 70% compared with peers relying mainly on CVSS-based prioritisation. The article, from The Hacker News, presents the Picus Platform as a way to put these elements into practice.

The source says severity-driven prioritisation made sense when attack surfaces were static and remediation capacity exceeded the number of disclosed flaws. That is no longer the case. Tens of thousands of new vulnerabilities appear each year across cloud, SaaS, identity and supply chain, and AI has shortened time-to-exploit from weeks or months to hours. The smarter approach is to measure success by the exploitable exposures you have reduced, not the number of vulnerabilities closed. This summary covers only the opening of the article.
