What is Controlled Unclassified Information in Cybersecurity?
Information that the US government creates or possesses (or that an entity creates or possesses on behalf of the government) that requires safeguarding or dissemination controls but is not classified. CUI includes categories like export-controlled technical data, law enforcement sensitive information, and certain types of financial and healthcare data shared with federal agencies.
Why Controlled Unclassified Information Matters for Your Cybersecurity Career
CUI handling requirements drive cybersecurity compliance programs across the entire defense industrial base. Contractors who process CUI must implement NIST 800-171 controls and will need CMMC certification. Security engineers must configure systems to protect CUI in transit and at rest. GRC analysts track CUI flows and ensure proper marking and handling procedures.
