Secure Signals Infrastructure (S2I) designs, develops and deploys cyber capabilities to the Army to establish cyber operational overmatch.  

S2I delivers capabilities to Army Service Component Commands (ASCCs) through divisions at the tactical edge that allow warfighters to understand and depict cyberspace while defending friendly key cyber terrain. S2I’s agile acquisition and integration processes achieve both near- and long-term capability development to ensure dominance in the cyber battlefield. 

Capabilities

• Tactical Defensive Cyberspace Operations (DCO) Infrastructure (TDI): Cyberspace defenders have the need to locally and remotely protect friendly tactical cyber terrain, maneuver in and across tactical enclaves, and counter cyber adversaries to ensure the reliability of critical tasks and services. TDI provides users with active hunt and defense tools to protect against cyber-attacks in the tactical network. The TDI system is physically and logistically converged with the Tactical Server Infrastructure (TSI) to minimize size, weight, and power (SWaP) requirements at Divisions and above. 
• Tactical Cross Domain Solution (TCDS): A critical component in military and defense operations, enabling secure, real-time sharing of information across different security domains. TCDS provides the Army a capability that enables information and communications to be shared and transmitted across different security domains in austere tactical environments. TCDS is a Low Size, Weight, Power and Cost (SWaP-C), rugged, tamper-resistant cross domain solution ideal for use in ground vehicles, mobile shelters, ground sensor systems, aircraft and UAVs.
• Command, Control, Communications, Computers, Intelligence, Surveillance, and Reconnaissance/Electronic Warfare (C4ISR/EW) Modular Open Suite of Standards (CMOSS) Mounted Form Factor (CMFF) Mounted Common Infrastructure (MCI): CMFF-MCI will provide the Army a capability that will converge communication, situational awareness, and positioning, navigation, and timing (PNT) capabilities into a single CMOSS compliant form factor (chassis) mounted on selected military platforms that can be employed on an operational environment. This capability will easily and rapidly equip ground vehicles and aviation platforms with capabilities like PNT, electronic warfare (EW) protection and others, through capability cards plugged into a common chassis. The CMFF Chassis will include smart display for user interface, including converging tactical communication waveforms; Mission Command applications; Assured Positioning, Navigation, and Timing (APNT); and Force Protection.
