US bans DeepSeek from federal agency systems under new DHS order

Ban blocks DeepSeek from US government use

The US Department of Homeland Security has issued an order banning DeepSeek software and services from all US federal civilian agencies, Reuters reported on October 19, 2026.

The order prevents the Chinese artificial intelligence company DeepSeek from operating on any information technology systems used by civilian government agencies across the United States.

Part of broader AI restrictions

The ban comes amid growing US concerns about the use of Chinese technology in government systems. US officials have been increasingly focused on restricting access to critical federal infrastructure by companies linked to China's technology sector, including both hardware and software providers.

DeepSeek, a Chinese artificial intelligence developer, had gained attention for its low-cost AI models that competed with more expensive offerings from US companies. Its rapid rise in popularity drew scrutiny from US regulators concerned about data security and foreign influence.

What the ban means

Federal agencies will now be prohibited from using DeepSeek's products or services on their IT systems. This means any current deployments of DeepSeek technology within civilian government operations would need to be removed or replaced.

The order specifically targets civilian agencies, not military or intelligence community systems, which are already subject to separate and often stricter review processes for Chinese technology.

Context within federal tech policy

The decision fits into a wider pattern of US restrictions on Chinese technology companies in the federal sector. Similar bans have affected other Chinese tech firms in recent years, particularly those involved in surveillance technology, telecommunications, and, more recently, artificial intelligence development.

Civil service and government IT workers have faced challenges as agencies adjust their technology stacks to comply with new restrictions. The Department of Government Efficiency, an initiative active during the second Trump administration, had already been overseeing changes to federal information systems and contract terminations across multiple agencies.

Reactions

The announcement was met with significant discussion online, drawing hundreds of comments on technology forums shortly after publication.
