DeepSeek's most widely used applications function through a prompt-and-response process that requires presenting information to the model, and which may result in the transfer of sensitive data to the PRC if used by U.S. government employees or vendors.
What it means for you
Our viewThis is a US federal civilian rule, so it binds agencies first, and its reach to third-party products developed using DeepSeek implementations may extend it to vendors who sell to them.
DHS gives its reason: it says DeepSeek's most widely used applications require presenting information to the model, which may transfer sensitive data to the PRC if government employees or vendors use them. How far the phrase about third-party products reaches is for the order's text to settle.
If you sell AI products to US federal civilian agencies, or build on DeepSeek models, ask your engineering team now whether any component uses DeepSeek, and read the order itself before an agency asks you.
It adds no new facts.
