What is "CUI"?

Controlled Unclassified Information (CUI) refers to a category of sensitive information that requires safeguarding or dissemination controls, even though it is not classified under Executive Order standards. The CUI program was established to standardize the way the federal government handles this type of information, ensuring that it is marked and protected consistently, while allowing for appropriate sharing among authorized users.

The significance of CUI lies in its distinction from classified information. While classified information is subject to stringent protective measures and involves national security implications, CUI encompasses a broader range of sensitive data that, if disclosed improperly, could still cause harm to individuals or organizations. Examples of CUI may include personally identifiable information (PII), proprietary business information, or sensitive but unclassified technical data.

Understanding CUI is crucial for compliance with regulations and for maintaining the integrity and security of sensitive information in various operational contexts. This foundational knowledge ensures that individuals handle this type of information appropriately, safeguarding it while enabling authorized access and sharing in line with regulations.
