DeepSeek banned from U.S. federal civilian agencies under new DHS order

The US Department of Homeland Security published a notice on 19 October 2026 ordering civilian agencies to remove DeepSeek products and third-party services built on DeepSeek models from their IT systems, and banning new acquisition. DHS cited possible data transfer to the PRC, intelligence gathering on US persons, and possible malware or vulnerabilities in the models. A July memo told agencies to monitor traffic to and from government websites. The Commerce Department, the Navy and several states had already restricted DeepSeek.
