Trump administration bans DeepSeek AI and all related technology from federal civilian agency computer systems

The Trump administration banned federal civilian agencies from using DeepSeek and all related technology in their computer systems, including third-party products and services developed based on its models, and barred these agencies from procuring DeepSeek products and services. The directive was issued by the U.S. Department of Homeland Security (DHS) on July 24 and applies to civilian agencies such as the Treasury Department, the State Department and the Department of Justice, but not the Department of Defense; DHS cited concerns that sensitive U.S. government data could be transferred to China and referenced open-source research pointing to multiple serious vulnerabilities in the DeepSeek iOS app. Agencies may submit written justification to apply for an exemption within 60 days after the directive is issued. Previously, the U.S. Navy, DISA, the Department of Commerce and Congress had each taken restrictive measures against DeepSeek, and Italy, Australia, Taiwan and South Korea had also fully or partially banned it; Chinese Foreign Ministry spokesperson Mao Ning expressed opposition to overgeneralizing the concept of national security and to politicizing science, technology and trade issues.
