The U.S. Department of Homeland Security signed an order restricting DeepSeek products in federal civilian agencies on July 24. The department made it public on October 19, months after it took effect. This is not a new nationwide ban on DeepSeek. MeriTalk reported on the disclosure.

The order applies to federal civilian agencies and their procurement. It does not prohibit businesses or individuals from using DeepSeek in the United States.

What the order covers

The order directs civilian agencies to stop buying covered products and remove them from agency information technology systems. It covers:

  • Products from DeepSeek and its affiliates.
  • Third-party products and services developed using DeepSeek implementations.
  • Products and services supplied to federal civilian agencies.

That last point matters for vendors. A product may fall within the order even if it does not carry the DeepSeek name. Suppliers may need to check which technology their services rely on, not just the labels on their products. The order also excludes national security systems. The signed order sets out its scope and an agency process for requesting exceptions.

Why the timing matters

The order was issued under the Federal Acquisition Supply Chain Security Act of 2018, following a recommendation from the Federal Acquisition Security Council. It was filed for public inspection on October 19 and scheduled for publication in the Federal Register on October 20.

The department cited concerns about data transfers, privacy and security vulnerabilities. Those are the stated grounds for the action, not a finding that every product using DeepSeek has caused a security incident.

For people using DeepSeek outside federal civilian systems, the notice announces no change. Its immediate effect is on government purchasing and agency technology, while its broader language may prompt suppliers to examine the technology behind their products. Yonhap also reported that the order does not amount to a general public-use ban.
