DHS Bans DeepSeek Technology Across US Federal Civilian Agencies

The U.S. ordered federal civilian agencies to stop purchasing DeepSeek products and services and remove them from government IT systems over national security concerns, according to the Department of Homeland Security. The restrictions also cover third-party offerings built with DeepSeek technology, though agencies can request exceptions. DHS warned that sensitive government user data could potentially be accessible to Chinese authorities under Chinese law; China opposed the move.

The US Department of Homeland Security has banned federal civilian agencies from using DeepSeek technology, requiring removal of existing products and prohibiting new purchases, according to the Wall Street Journal. The order also covers affiliated companies and third-party services built with DeepSeek implementations. It specifies neither a removal deadline nor particular security concerns, and whether AI gateways such as OpenRouter fall within its scope remains unclear.
