US Orders Federal Agencies to Remove DeepSeek AI From Government Systems
DHS ordered federal civilian agencies to remove DeepSeek products and stop buying them. Here is what the order covers, what it does not, and what it means for AI.
The short answer
A Federal Register notice published October 20, 2026 says the Secretary of Homeland Security ordered two things: federal civilian agencies may not buy DeepSeek technology, and they must remove DeepSeek products, including third-party products built using DeepSeek, from their IT systems. It is a rule for government systems and purchases, not a nationwide ban on ordinary people or companies using DeepSeek.
DHS ordered federal civilian agencies to remove DeepSeek products and stop buying them. Here is what the order covers, what it does not, and what it means for AI.
01 / The story
What the US government actually ordered
The Department of Homeland Security published a notice in the Federal Register on Tuesday, October 20, 2026, titled "Notice of Order Regarding Exclusion and Removal of DeepSeek Products From Federal Civilian Executive Branch Information Technology Systems and Procurements" [1].
According to the notice, the Secretary of Homeland Security issued an order that does two things [1]:
- Exclusion: federal civilian agencies may not buy IT products and services developed by Hangzhou DeepSeek Artificial Intelligence Co., Ltd., including its affiliated entities.
- Removal: agencies must remove all DeepSeek and DeepSeek-affiliate products, and third-party products and services developed using DeepSeek implementations, from civilian agency IT.
02 / The story
Which law allows this?
The notice cites the Federal Acquisition Supply Chain Security Act of 2018 (41 U.S.C. 1321-1328) and its rules at 41 CFR 201-1 [1][2]. That law created the Federal Acquisition Security Council, which can recommend that risky suppliers be excluded or removed from federal systems. The notice says the order followed a review of the Council's recommendation and related evidence [1].
Implementation questions are handled by a FASCSA order team in CISA's Cybersecurity Division, the notice says [1]. The signed order is in docket DHS-2026-0628 on regulations.gov [3].
03 / The story
Is this a nationwide DeepSeek ban?
No. Based on the notice, the order applies to federal civilian executive branch agencies: their IT systems and their purchases [1]. It does not say that private citizens, schools or businesses must stop using DeepSeek.
Two important limits to keep in mind: the notice is about civilian agencies, so it does not by itself describe rules for the military; and any contractor obligations, deadlines or exceptions should be confirmed in the signed order, not assumed.
| Question | What the notice says |
|---|---|
| Who must comply? | Federal civilian executive branch agencies [1] |
| Buying DeepSeek tools? | Excluded from federal civilian procurements [1] |
| Tools already installed? | Must be removed from civilian agency IT [1] |
| Tools built on DeepSeek? | Third-party products developed using DeepSeek implementations are included [1] |
| Ordinary people and companies? | Not covered by this notice |
04 / The story
Why the third-party rule matters most
DeepSeek publishes open-weight models that anyone can download and build into their own software [4]. Because the removal covers third-party products developed using DeepSeek implementations [1], an agency could be affected even if it never used DeepSeek's own app.
That makes model supply chains a practical issue: agencies and their vendors now need to know which models sit underneath the tools they buy. Exactly how "developed using DeepSeek implementations" is interpreted in practice is a detail readers should check in the signed order and any CISA guidance.
05 / The story
Why officials see a security concern
The public text of the notice does not list specific incidents; it refers to the Security Council's recommendation and supporting evidence [1]. We therefore do not claim any particular data leak or attack.
General concerns raised about AI services include where user data is stored and which laws can force access to it. DeepSeek's own privacy policy says the information it collects is stored on servers in the People's Republic of China [5]. Storing data abroad is not proof of misuse, but it is the kind of risk supply-chain reviews consider.
06 / The story
What it means for the AI industry
The order shows that governments are starting to review AI models the way they review hardware and software suppliers. For AI vendors selling to the government, documenting which models power a product is becoming part of the sale.
For everyday users, nothing in this notice changes whether DeepSeek is legal to use. People should still choose AI tools carefully, avoid pasting sensitive data into any chatbot, and read privacy policies. For background on DeepSeek's models, see our earlier coverage of its open-weight releases.
A closer look
How we checked this story
We read the official Federal Register notice on GovInfo directly. The signed order itself is attached to the notice as scanned pages, so details that appear only in those pages, such as deadlines or exceptions, are not repeated here unless confirmed in text.
We did not find an official response from DeepSeek to this specific order at the time of writing, and we do not quote unverified reactions from any government.
