Executive Summary
U.S. federal civilian agencies must remove DeepSeek-related products and cannot make new purchases from DeepSeek or its affiliates. Government and enterprise teams using third-party AI components should identify dependencies and assess supply-chain and governance exposure.
What Happened
U.S. federal civilian agencies must remove DeepSeek products from their information technology systems, along with any third-party products or services "developed using DeepSeek implementations," under a Department of Homeland Security order. They may also no longer buy information technology products or services from the Chinese AI developer or its affiliates Homeland Security Secretary
Affected Products
- DeepSeek products
- Third-party products or services developed using DeepSeek implementations
Vulnerability / Attack Technique
AI supply-chain dependency exposure
Technical Mechanism
The reported order targets DeepSeek products installed in federal civilian information technology systems, as well as third-party products or services developed using DeepSeek implementations. It also prohibits new purchases of information technology products or services from DeepSeek or its affiliates.

Relevant Frameworks
RealGround Analysis
Teams running AI agents or LLM applications may inherit security, compliance, and operational risk through embedded models, services, or implementations that are not fully inventoried. Maintaining an AI component inventory and reviewing provenance, dependencies, and procurement restrictions can support faster risk decisions and replacement planning.
Recommended Controls
- Maintain an inventory of all models, AI services, libraries, and third-party products used by AI applications and agents.
- Record model and provider provenance, including whether products depend on or were developed using restricted implementations.
- Perform supply-chain security and compliance reviews before procuring or integrating third-party AI products.
- Use an AI component bill of materials and dependency mapping process to identify affected systems quickly.
- Establish documented governance procedures for suspending, replacing, or approving AI components subject to regulatory or procurement restrictions.
