DHS orders civilian agencies to remove DeepSeek and halt buys
First merged summary.
A July 24 DHS order, published October 20, bars federal civilian agencies from buying or keeping DeepSeek and related tools, with CISA exceptions.
The U.S. Department of Homeland Security ordered federal civilian agencies to stop buying Hangzhou DeepSeek products and remove them, including affiliates and third-party tools built with DeepSeek implementations. Secretary Markwayne Mullin signed the supply-chain order on July 24, 2026; it was published October 20 as document 2026-21447. Several outlets say it cites China-based servers and possible data or model risks without a confirmed breach; The Hacker News and The Decoder say the notice states no specific security reasons. Defense and intelligence systems and private users are excluded. Agencies may request CISA-reviewed exceptions. Security Affairs says the ban took effect when signed, while CSO Online reports a 60-day removal window and The Decoder reports no deadline.
