The CAC Security Assessment is a regulatory review conducted by the Cyberspace Administration of China for specific cross border data transfers.

Companies must apply for this assessment when transferring large volumes of personal information or important data overseas. The authority reviews the purpose of transfer, security measures, foreign recipient safeguards, and potential risks to national security. Approval is required before the transfer can proceed.

The assessment process can involve detailed documentation and risk analysis. Businesses must prepare carefully and ensure strong internal controls before applying.
