Protocol Free Encryption Device (PFED) for Sensitive But Unclassified Networks Request for Information (RFI) 1. Description The Capability Program Executive Command (CPE) and Control Information Network (C2IN), Product Manager Communications Security (PdM COMSEC) is seeking information on available commercial-off-the-shelf (COTS) solutions for protocol-agnostic inline network encryption on the United States Army's Sensitive But Unclassified Encrypted (SBU-E) Networks. The goal is to secure high-speed, point-to-point data links by providing transparent, "bump-in-the-wire" encryption at the Physical or Data Link layer (OSI Layer 1/2). This RFI is to conduct market research on available PFEDs, to gauge industry interest for potential Bailment and Government evaluation. Information gathered will be used to collaborate with Subject Matter Experts (SMEs) and operational units to define possible use cases for these technologies. The ultimate objective is to gather sufficient data to determine whether adopting these items will improve or hinder the effectiveness and efficiency of current field operations. 2.
