Inside the customer environment: Where threat actors, vulnerabilities, and exposed assets intersect

Tenable Blog · 27 May 2026

Tenable Research has developed a graph-based model linking 600+ threat groups to real-world customer exposures. It reveals which vulnerabilities sit at the intersection of severity, active exploitation, and organizational risk.Key takeawaysThe "patch everything" strategy is dead: Vulnerability prioritization based on exploitation risk offers a path forward. A directed graph model linking 600+ threat actors to vulnerabilities in 7,800 customer environments reveals that 68% of organizations carry at least one CVE previously exploited by a named adversary, and 321 tracked threat groups can...

Reducing Remediation Time Remains a Challenge: How Tenable Vulnerability Watch Can Help

Tenable Blog · 25 Apr 2025

Timely vulnerability remediation is an ongoing challenge for organizations as they struggle to prioritize the exposures that represent the greatest risk to their operations. Existing scoring systems are invaluable but can lack context. Here’s how Tenable’s Vulnerability Watch classification system can help.BackgroundOver the past six years working in Tenable’s research organization, I’ve watched known vulnerabilities and zero-day flaws plague organizations in the immediate aftermath of disclosure or even years afterwards. Following each blog post or threat report we’ve published, I kept...
