Controlled Unclassified Information

Controlled Unclassified Information (CUI) is sensitive but unclassified government information that requires safeguarding or specific handling procedures according to laws and regulations. It includes data like personal details, proprietary business information, or security-related material that isn't classified as top secret or confidential but still needs protection to prevent misuse, theft, or harm. Agencies and organizations must follow established safeguards to ensure CUI remains secure while allowing authorized access for legitimate purposes. Essentially, CUI is important information that isn’t secret but still needs careful management to protect individuals, organizations, and national interests.
