The order, issued by DHS Secretary Markwayne Mullin, requires all civilian federal agencies to remove DeepSeek products and any third-party services built using its implementations. Signed as early as June 26 and made public on October 19, the directive cites risks of sensitive data transfer to China and potential malware within the models. The ban operates under the Federal Acquisition Supply Chain Security Act of 2018, and the Federal Register publishes the official notice this Tuesday. Agencies may request exceptions by filing a justification 60 days in advance, though national security systems remain outside the order's scope.
