Government Responses

CISA Delays Final Cyber Incident Reporting Rule

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) announced a delay in the finalization of its cyber incident reporting rule for critical infrastructure operators. Originally scheduled for October 2025, the rule’s publication has been pushed to May 2026. The delay follows significant industry and legislative feedback, with concerns raised about the scope, burden, and clarity of the proposed requirements. The rule, mandated by the Cyber Incident Reporting for Critical Infrastructure Act (CIRCIA) of 2022, will require covered entities to report major cyber incidents within 72 hours and ransomware payments within 24 hours. CISA is using the additional time to harmonize the rule with other federal requirements and address stakeholder concerns7​8.

• Agency: CISA
• Rule: Cyber Incident Reporting for Critical Infrastructure Act (CIRCIA)
• New Deadline: May 2026
• Key Issues: Scope, compliance burden, harmonization with other regulations
