DHS orders federal agencies to purge and ban DeepSeek products
The U.S. Department of Homeland Security (DHS) has formally ordered all federal civilian agencies to strip AI technology developed by Chinese company Hangzhou DeepSeek (DeepSeek) from their IT systems and to bar future purchases of its products and services — a comprehensive federal-level ban following earlier state-level restrictions.
Confirmed
- Per WSJ relayed by @firstadopter, DHS notified federal civilian agencies to remove DeepSeek technology from IT systems and banned future procurement
- @rohanpaulai noted the order was issued under the 2018 Federal Acquisition Supply Chain Security Act, with the document published in the Federal Register
- The ban covers Hangzhou DeepSeek and its affiliates; the scope extends beyond DeepSeek itself to third-party products and services built on DeepSeek implementations
- @cephaloform added that the order was originally issued on July 24, and procurement must exclude DeepSeek-related products
- @nathanbenaich shared a report from monitoring account MTSlive, saying the move cites national security and escalates beyond state-level restrictions
Why it matters
- The ban is the first to include "third-party products and services built on DeepSeek implementations," meaning any vendor indirectly using DeepSeek models could be shut out of federal procurement
- Executing the ban via the Federal Acquisition Supply Chain Security Act provides a reusable legal template for similar supply-chain bans targeting foreign AI/IT products, and could extend to other Chinese AI companies
