[U.S. Department of Homeland Security Requires Civilian Agencies to Remove DeepSeek and Prohibits New Procurement]

The U.S. Department of Homeland Security (DHS) on Monday instructed U.S. civilian agencies to remove products of Chinese IT company AI from government DeepSeek systems, as well as any third-party services built on the model, and prohibited new procurement. The notice stated that using DeepSeek could result in sensitive data being transferred to China and could generate intelligence targeting U.S. individuals and institutions.DHS stated that these models constitute “multiple threat vectors.” The ban targets not only DeepSeek's own applications, but also third-party services developed based on it. A July DHS memorandum was made public on Monday, after agencies had already been required to monitor DeepSeek-related risks in traffic to and from government websites. The U.S. Department of Commerce, the Navy, and the states of New York, Tennessee, and Virginia had previously restricted DeepSeek. The Federal Communications Commission (FCC) will vote on October 29 on whether to ban all Chinese laboratories from testing electronic products used in the United States.DeepSeek is a Hangzhou-based startup whose open-source model drew widespread attention in January 27, 2025, with development costs of less than 5000000 USD, causing Nvidia's share price to fall 16%that day and wiping approximately 600000000000 USD。2025 in market capitalization. In April, the U.S. House Select Committee on the Chinese Communist Party said that DeepSeek may have secretly sent U.S. user data to the Chinese government and may have used approximately 60000 Nvidia chips, of which 20000 were subject to U.S. export-control restrictions.DeepSeek This year,April released a preview of its V4-Pro model, priced approximately GPT-5.5 lower than OpenAI's 98%Pro, and made it available for free download and modification under the MIT license; this week, it also released an updated V4.1-Flash model version optimized for efficiency.

AI-assisted interpretation

The following is analysis, separate from reported facts. Verify important claims independently.

This means that the scope of the ban described in the original text covers not only DeepSeek's own applications, but also third-party services developed using its models.DHS The stated rationale is sensitive-data and intelligence security risks.

Why it matters to readers

If the requirements described in the original text are implemented, the relevant civilian agencies will need to inspect government IT systems, remove covered products or services, and halt new procurement. Whether third-party services are based on DeepSeek models will also be a key focus of review.

Ordinary users should understand this content as a report on government IT security and procurement restrictions, rather than as proof that DeepSeek necessarily transfers data. When using related services, they can pay attention to data-handling practices, formal agency notices, and the specific scope of application.

Risks and unknowns

The evidence provides only Telegram channel content and does not include the original DHS formal notice or memorandum; the ban's precise scope, release date, and implementation details cannot be confirmed.
“Could result in sensitive data being transferred to China” and “could generate intelligence” are risk assessments in the notice; they do not mean that the original text provides evidence that this actually occurred.
The special committee's claims regarding user data and the number of chips are qualified as “may”; the original text provides no supporting materials.
