Is DeepSeek Banned in the US? What the DHS Order Actually Covers
No — DeepSeek is not banned for individuals in the United States. The order people are talking about applies to federal civilian agencies, not to personal or ordinary business use. It tells those agencies to stop buying DeepSeek products and to remove DeepSeek, its affiliates and third-party products built using DeepSeek from agency IT systems.

What did the US government actually order?
The Department of Homeland Security filed notice of the order on October 19, 2026, and it is scheduled to publish in the Federal Register on October 20. The order was signed in July and made public this week, Reuters reported.
It has two parts:
- Exclude information technology products and services developed by Hangzhou DeepSeek Artificial Intelligence Co., Ltd. and its affiliates from federal civilian agency procurements.
- Remove DeepSeek and DeepSeek-affiliate products, plus "third-party products and services developed using DeepSeek implementations," from civilian agency IT systems.
DHS issued the order under the Federal Acquisition Supply Chain Security Act of 2018 (41 U.S.C. 1321–1328), the same authority the government uses to keep risky vendors out of federal supply chains. CISA's FASCSA Order Implementation Team is handling questions about it.
The second clause is the one that travels furthest. DeepSeek releases open-weight models, so its technology can sit inside another company's product without that company being called DeepSeek. The order does not publish a list of affected third-party products, and it does not spell out how agencies should treat a DeepSeek model that a US company hosts on its own servers. That ambiguity is now a compliance question for vendors selling into the federal market.
Who the order covers — and who it does not
| Group | Covered by this order? | What it means |
|---|---|---|
| Federal civilian executive branch agencies | Yes | Stop buying DeepSeek products; remove DeepSeek-based products from agency systems |
| Military and intelligence systems | No | National security systems and secure compartmented information systems are outside this order |
| Federal contractors and vendors | Indirectly | If you sell to covered agencies, you may have to show whether your product uses DeepSeek |
| State and local governments | Not by this order | Some states have their own DeepSeek restrictions |
| Private companies | No | No general ban on using DeepSeek in your own business |
| Individual users | No | Personal use of DeepSeek is not prohibited by this order |
That table is the short answer to most of the "is DeepSeek banned" searches. The order is a procurement and government-IT rule. It is not a nationwide consumer ban, and it does not make it illegal to open DeepSeek's website or app.
It also does not reach every part of the US government. The order applies to civilian agencies, not to military and intelligence systems. Reuters notes that several agencies, including the Commerce Department and the Navy, had already restricted DeepSeek on government devices, and that New York, Tennessee and Virginia took similar steps. Those earlier actions were narrower than this order, which covers every civilian agency and what it buys.
Does the order affect individual users?
No. If you use DeepSeek at home, on your phone or in a small business that does not sell to the federal government, this order does not change your legal position.
There are three practical caveats, though:
- Your employer may have its own rules. A company that contracts with the government can adopt stricter internal policies than the law requires. Check your IT policy before pasting work material into any AI tool.
- State and local rules can differ. The federal order does not override state restrictions on government devices or state procurement.
- The policy conversation may continue. A government order aimed at agencies can shape what large vendors offer and what buyers ask about. It does not ban the model for everyone, but it can change how DeepSeek-based products are sold.
What it means if you sell to the US government
If you are a federal contractor, the important sentence is "third-party products and services developed using DeepSeek implementations." It means the compliance question is not only "do we use DeepSeek?" but also "does any component in our stack use DeepSeek?"
In practice, vendors selling to civilian agencies should be ready to answer:
- Which model providers and open-weight models are in the product?
- Is any model hosted, fine-tuned or distilled from DeepSeek?
- Can the product run without a DeepSeek dependency if a customer requires it?
- Where is inference data processed and retained?
The order does not answer those questions for you, and it does not list which products are caught. That is why the safest reading for a vendor is to map the model supply chain before an agency asks.
Is DeepSeek safe to use?
"Banned for agencies" and "unsafe for you" are different claims. The DHS order cites security and data-risk concerns: DeepSeek's servers are in China, Chinese law gives authorities broad access to company infrastructure, and the sign-up process collects personal information. Reuters reports that DHS warned use by government employees or vendors "may result in the transfer of sensitive data" and that the models "may contain malware or other security vulnerabilities."
Those are reasons for a government agency to keep sensitive work off the service. They are not proof that every consumer query is stolen, and the order does not describe a specific case of government data reaching DeepSeek.
For an individual or a private company, the useful rule is the same one that applies to any hosted AI tool:
- Do not paste confidential documents, credentials, personal data or unreleased business information into a free consumer chat.
- Treat the model provider as a third party that can see your prompts and outputs.
- If you need DeepSeek's model but not DeepSeek's account system, use a host whose data policy you have actually read.
- For regulated or contract-sensitive work, follow your organization's policy rather than a general article.
How to keep using DeepSeek
The order does not stop you from using DeepSeek as an individual. If you want the model without creating a DeepSeek account, aiwith hosts DeepSeek V4.1 Flash and DeepSeek V4 Pro in a browser chat. The same account also gives you other models for comparison:
- GPT-6 — GPT-6 Astra, GPT-6.1 Sol and GPT-6 Luna.
- Claude — Claude Fable 5.1 and Claude Opus 5.5.
- Gemini 3.1 — Gemini 3.1 Pro and Gemini 3.6 Flash.
- Kimi K3 — long-context work and document-heavy tasks.
One honest warning: if you are a federal agency or a contractor covered by this order, using DeepSeek through a third-party chat front-end does not change the model and does not take you outside the order. The order is about the model and the product, not about which website you type into. For personal use, the choice is yours.
If you specifically want to know whether DeepSeek's own chat costs money or requires an account, we covered that separately in Is DeepSeek free? and DeepSeek without login.
What happens next
The notice is scheduled for publication on October 20, 2026. After that, the practical questions are enforcement and exceptions: how agencies document removal, how CISA reviews requests for relief, and how vendors prove a product has no DeepSeek dependency.
For now, the accurate one-line answer is: the US government has restricted DeepSeek inside federal civilian agencies, not for the general public. Searches that say "DeepSeek is banned in the US" without that qualifier are describing a much broader rule than the one DHS published.
