US department cites risks of data leaks and security vulnerabilities as reasons for banning products from DeepSeek

confirmed by 2 independent sources updated October 25, 2026

The US Department of Homeland Security cites the risk of data leaks to China and possible security vulnerabilities as reasons for banning products from DeepSeek. Civilian federal agencies must remove the products and may no longer purchase them.

The US Department of Homeland Security cites the risk of sensitive data leaking to China and possible security vulnerabilities as reasons for banning products from DeepSeek. These are security concerns the department uses to justify the measure, rather than an announcement of a specific data leak.

The directive requires US civilian federal agencies to remove all products from DeepSeek from their information systems and prohibits future purchases of those products. It also applies to software from other suppliers based on open models from DeepSeek.

The Chinese Ministry of Commerce is demanding that the ban be lifted and has announced that it will take countermeasures. The Chinese Ministry of Foreign Affairs accuses the US of interpreting national security too broadly.

What changed

Why it matters

For software suppliers serving US civilian federal agencies, the underlying model also matters: the ban includes products from other companies based on models from DeepSeek. Switching suppliers alone may therefore not ensure compliance with the measure.
