The SOSSEC Consortium (System of Systems Security Consortium) manages multiple high-impact DoD Other Transaction Authority (OTA) vehicles that enable rapid prototyping, field demonstration, and accelerated technology transition for digital modernization and cyber-secure mission systems. Key OTA programs under SOSSEC management include the PEO C4I OTA, the PEO Digital/AFLCMC OTA, and additional mission-aligned vehicles supporting Army, Navy, Air Force, and Joint modernization priorities. Unlike FAR-based acquisition, SOSSEC OTAs streamline contracting and encourage participation from nontraditional performers, commercial innovators, academic teams, and engineering firms capable of advancing critical capabilities without the long administrative cycles typical of federal procurement. 

Solicitations managed through SOSSEC emphasize cyber defense, mission-secure networking, C4ISR modernization, secure communications, cloud-to-edge architectures, zero-trust implementation, AI-enabled mission analytics, resilient tactical data fabrics, digital logistics, and large-scale interoperability for system-of-systems environments. As mission complexity increases across military operations, uninterrupted data flow, decision agility, cyber dominance, and secure cross-domain information exchange are essential to readiness, survivability, and operational effectiveness. 

SOSSEC OTAs support rapid testing and ruggedization for contested environments, including hardened networks, distributed command-and-control, multi-domain sensor fusion, active cyber defense, and resilient mission-command systems that maintain continuity under degraded conditions. Projects may include next-generation encryption, secure waveform development, cognitive EW, hardened cloud orchestration, cyber-aware edge compute modules, digital modernization tools for Joint operations, AI-enhanced situational awareness, and adaptive mission-command platforms interoperable across Service branches and coalition environments. 

A major strength of SOSSEC is its ability to accelerate cross-domain integration, enabling solutions that connect intelligence, logistics, cyber operations, aviation, maritime, ground systems, ISR payloads, and strategic command frameworks. Proposal evaluations emphasize technical rigor, manufacturability, rapid demonstration feasibility, dual-use relevance, cyber survivability, data-layer interoperability, and a clear transition pathway to operational deployment. Many solicitations begin with a short, highly technical white paper, encouraging participation from innovative performers without requiring upfront full proposals. 

Because the digital battlefield increasingly depends on secure networking, data fusion, AI-enabled insight generation, electromagnetic resiliency, and Joint force synchronization, the SOSSEC Consortium plays a central role in accelerating next-generation cyber and digital modernization for the DoD. System-of-systems interoperability is now a strategic imperative, and OTA structures give the Department the agility to deploy commercial or academic innovation rapidly, test it directly with end users, iterate design, and scale toward national defense infrastructure.
