CISA's Binding Operational Directive 26-04 makes it official: vulnerability management is no longer about how many CVEs you close, but which exposures actually put critical operations at risk. Though binding only on federal civilian agencies, it sets the new bar for audit, insurance and board-level expectations across every sector.

See what's required — and how to get ahead of it — by reading the Gartner^® First Take: CISA Redefines Exposure Management as a Risk-Based Discipline. It provides an overview of the directive, immediate actions cybersecurity leaders should take and insights including:

"BOD 26-04 transforms vulnerability management from a technical

hygiene function into a core risk management discipline.

Cybersecurity leaders who fail to adapt will waste resources

patching low-impact issues, miss high-impact threats, and struggle

to justify decisions to regulators and boards."

‍How Nozomi Networks helps you operationalize a risk-based approach:

• Know what's at stake. Gain continuous visibility into every OT, IoT and IT asset — with the context to pinpoint which systems are truly mission-critical.
• Prioritize by real-world risk. Correlate vulnerabilities with live threat intelligence and known-exploited activity, moving beyond CVSS to exploitability plus impact.
• Report risk the board understands. Translate technical findings into business-aligned exposure metrics that prove risk reduction on critical systems.
