The United States has ordered federal civilian agencies to remove DeepSeek, the Chinese artificial intelligence company’s products, from their computer systems. The order was issued by the Department of Homeland Security (DHS) on Monday, 19 October 2026. It also covers other services that are built on DeepSeek’s technology. Here is what the order says, why DHS issued it and who it does and does not affect.
What the Order Says
According to Decrypt and Techzine:
- Civilian government agencies must remove DeepSeek products from their IT systems.
- They must also remove third-party products and services that use DeepSeek’s models.
- Agencies can no longer buy DeepSeek products.
- Vendors that built DeepSeek models into their solutions are affected.
Neither report gives a deadline for agencies to comply, and neither mentions exemptions for government bodies.
The Legal Basis
Techzine says the order follows a security assessment by the Federal Acquisition Security Council and uses the Federal Acquisition Supply Chain Security Act of 2018. That law lets the government exclude technologies that pose supply-chain security risks. Decrypt links to a Federal Register notice, but it does not describe the legal basis itself.
Why DHS Says It Acted
DHS says DeepSeek’s models pose “multiple threat vectors.” Decrypt reports that DHS warns using them “may result in the transfer of sensitive data to the PRC” (People’s Republic of China) if employees or vendors use them. DHS also said they could produce “actionable intelligence on U.S. persons and/or government agencies.” The Chinese Embassy in Washington had not immediately commented, according to Decrypt. These are DHS’s claims. The reports I read do not include evidence made public, and they do not include a response from DeepSeek.
Who Is Not Affected
Techzine says the restrictions do not apply to private companies or individual users. The order covers federal civilian agencies, not the military, and the reports do not say how the military is treated. Some US agencies have already acted separately. The Commerce Department and the Navy banned DeepSeek on government devices earlier, and New York, Tennessee and Virginia have taken similar steps.
Earlier Steps
Decrypt reports that a July DHS memo, made public on Monday, had already told agencies to watch traffic to and from government websites for risks linked to DeepSeek.
The Wider Picture
The order comes during continuing technology tensions between the US and China. Decrypt notes that the US Federal Communications Commission is due to vote on 29 October on barring Chinese labs from testing electronics for use in the US. DeepSeek, meanwhile, continues to build its models. Techzine notes that it recently released a model called V4.1 Flash-1017.
What This Means for Everyday Users
- The order does not stop individuals or private companies from using DeepSeek.
- It does not apply to Pakistan or to Pakistani users.
- Companies that sell to the US government may need to check whether their products use DeepSeek models.
- Anyone using any AI service for work should think about what data they paste into it, whichever company runs it.
