Controlled Unclassified Information (CUI) refers to sensitive federal data that, while not classified, requires safeguarding under federal law and agency policies. As cyber threats continue to escalate, the U.S. Department of Defense (DoD) has prioritized CUI protection across its contractor ecosystem.
