Major rules for federal contractors handling sensitive data are nearing the finish line

New federal rules for contractors handling sensitive data are nearing finalization.

New federal regulations are expected soon for government contractors handling Controlled Unclassified Information (CUI), a category of sensitive but unclassified data. These rules will mandate minimum cybersecurity standards and require reporting of breaches, including cyberattacks, within 72 hours. This aligns with CISA's reporting requirements for critical infrastructure and could expose non-compliant contractors to penalties under the False Claims Act.

The lesson from this incident

Full lesson

Federal contractors handling Controlled Unclassified Information (CUI) have long operated without uniformly enforced minimum cybersecurity standards, creating inconsistent protection of sensitive government data across the supply chain. The incoming regulations will mandate baseline security controls and require breach reporting within 72 hours, closing a significant accountability gap. Non-compliance could trigger False Claims Act penalties, meaning cybersecurity failures could now carry serious financial and legal consequences. This regulatory shift underscores that protecting government-sensitive data is not optional — contractors must treat CUI security with the same rigor as classified information. Organizations that have delayed building mature security programs now face a hard deadline with real enforcement teeth.
