DHS discloses an immediate federal civilian exclusion order for DeepSeek
2026-10-19Verified announcementWATCH
The U.S. Department of Homeland Security publicly filed notice of an exclusion and removal order covering DeepSeek, affiliated entities and third-party products or services developed using DeepSeek implementations in federal civilian agency IT. The signed order is dated July 24, 2026 and required exclusion and removal immediately upon issuance; the Federal Register notice is scheduled for October 20. Agencies may seek written exceptions within 60 days.
What this means for you
For vendors serving U.S. federal civilian agencies, this is broader than blocking the official DeepSeek app: the wording reaches affiliates and third-party products developed using DeepSeek implementations. Procurement and software-supply-chain teams need an inventory and legal interpretation, while non-federal users should not assume the order is a general U.S. ban.
