Why it matters
The DeepSeek ban makes visibility into model dependencies and AI-gateway routing important for federal defenders enforcing restrictions on approved AI providers.
The US Department of Homeland Security ordered federal civilian agencies to stop using and remove DeepSeek and affiliated products, including third-party products and services developed using DeepSeek implementations. The report highlights ambiguity in the order’s scope and warns that AI-gateway routing could leave agencies using DeepSeek models unknowingly.
