The U.S. Department of Homeland Security orders civilian federal agencies to remove DeepSeek products and related third-party services from government IT systems. The directive also tells agencies to stop purchasing DeepSeek offerings, citing national security concerns.

The order, issued under a 2018 supply chain security law, applies not only to DeepSeek’s direct products but also to technology developed by DeepSeek affiliates and third-party tools built using DeepSeek’s model implementations. Outlets report that the rationale includes concerns that sensitive government data could be shared with servers in China, along with risks such as potential malware or other threats to federal IT systems.

Reporting also frames the move within broader U.S.-China technology and security dynamics, noting that DeepSeek’s open-weight models and lower cost make it increasingly visible to developers and vendors. While the specific operational steps for compliance are not the same across accounts, all describe a government-wide action targeting DeepSeek in civilian agency environments and future procurement.
