Reality Defender Platform

Description: On September 3, 2026, the U.S. Department of Homeland Security’s Homeland Security Investigations (HSI) Office of Acquisition posted this active Special Notice for the Reality Defender synthetic-media detection platform. The notice says the agency intends to solicit from a single source because the contracting officer determined that only one responsible source can satisfy the requirement, while inviting interested parties to submit a brief description of relevant experience. Responses are due September 10, 2026, at 12:00 PM EDT; SAM.gov classifies the record as an active contract opportunity rather than a grant program and lists no attachments or links.
