The Department of Defense, specifically the Program Executive Office Command Control, Communications: Tactical (PEO C3T), is seeking recommendations for hardware and software architecture related to Cross Domain Solutions (CDS) to enhance interoperability between security domains. The objective is to develop a CDS that meets the National Cross Domain Strategy Management Office (NCDSMO) requirements, enabling the secure transfer of information across multiple security domains, which is critical for effective Warfighter operations and intelligence sharing. Interested vendors must submit their responses electronically by noon (12 PM) EST on November 15, 2024, and are encouraged to address specific requirements outlined in the Request for Information (RFI), including compliance with IPv4 and IPv6 standards and support for high-threat networks.
