# BlastRadius: Why Severity Scores Lie, and How Graph AI Solves Real Attack Paths
"Defenders think in lists. Attackers think in graphs. As long as this is true, attackers win." — John Lambert, Distinguished Engineer, Microsoft Threat Intelligence The 2:00 AM Alert Delusion It is 2:14 AM. Your security scanner finishes sweeping your hybrid cloud infrastructure and drops a fresh spreadsheet into your ticketing queue: 4,821 open vulnerabilities . Two hundred of them are flagged…
The article discusses the limitations of current cybersecurity practices, particularly the reliance on CVSS severity scores to prioritize vulnerability remediation efforts. It highlights the flaw in the common approach of sorting vulnerabilities by CVSS score and patching from most critical to least, as this method does not take into account the actual attack paths an adversary could take within a network.
The author uses an example where a less severe vulnerability on an internet-facing API gateway was exploited to compromise the entire customer database, while more severe vulnerabilities on isolated, air-gapped servers went unnoticed. The article introduces BlastRadius, a graph-native AI solution that addresses this issue by mapping true network reachability, identifying topological choke points, and automatically remediating attack paths without disrupting production systems.
