What changed

The Department of Homeland Security notice was published on 19 October, Silicon Republic reports. It says federal civilian agencies must remove DeepSeek-related products already in use, including third-party services developed using DeepSeek’s AI.

The notice also bars agencies from future purchases of IT made by DeepSeek or by companies connected to it through a third party, according to the report. That sets out procurement restrictions alongside the removal order, rather than leaving the policy at a general ban on DeepSeek products.

Silicon Republic says the ban itself took effect in July, months before the notice was published. It also reports that agencies within the Department of Defense are excluded.
