CIRCIA final rule sent to OMB for review

What changed

CISA sent the final rule under the Cyber Incident Reporting for Critical Infrastructure Act to the White House Office of Management and Budget for review on October 1, 2026, the last procedural stage before publication. The rule would require covered entities across sixteen critical infrastructure sectors, an estimated 300,000 or more, to report substantial cyber incidents within 72 hours and ransomware payments within 24 hours. The scope could extend to technology, cloud, logistics, engineering and communications vendors serving critical infrastructure clients. Publication is expected before year end.

Why it matters

  • Covered entities would report substantial cyber incidents within 72 hours and ransomware payments within 24 hours.
  • An estimated 300,000 or more entities across sixteen critical infrastructure sectors could be covered.
  • Technology, cloud, logistics, engineering and communications vendors serving critical infrastructure could fall within scope.

Our comment

The rule is not yet in force, but its scope could reach vendors that do not consider themselves covered entities. The question for technology providers serving critical infrastructure clients is whether they would fall within the definitions and how the reporting timelines would interact with existing contractual and regulatory notification duties.
