What EWA-GSI does

Sigma Defense Systems LLC, operating publicly under the Sigma Defense brand and historically associated with the EWA-GSI entity founded in 2002 and headquartered in Herndon, Virginia, is a privately held U.S. defense technology contractor serving the U.S. Department of Defense, all major military branches (Army, Navy, Marines, Air Force, Coast Guard), U.S. Special Operations Command (SOCOM and JSOC), and coalition partners. The company employs 101-250 people and delivers mission-critical systems across C5ISR, Combined Joint All-Domain Command and Control (CJADC2) integration, secure networking and communications, cyber operations, radar design, electronic warfare, and training simulation.

Its technology stack centers on three interlocking platforms: Olympus, positioned as the first technology ecosystem dedicated to enabling CJADC2; Sigma Software Studio, the U.S. Navy's de facto DevSecOps platform with Authority to Operate; and the Aries Edge / TCS-CS-RSI solution, which is the Marine Corps Ground Sensors Program of Record. Around these platforms sit more than a dozen fielded products including the NEOS Dual tactical radio, Recon V OverWatch R50 and CheckPoints surveillance systems, the Stingray Tactical Relay System, OverWatch battle management, OWIK integration kit, Software-Defined Networking, Expeditionary Communications and Broadband Kits, COMSEC ancillaries, DECTK, and the Battle Force Warfare Electronic Trainer. The portfolio spans tactical edge sensors, secure networking hardware, mission software, and electronic warfare training.

Revenue is generated primarily through negotiated defense contracts and program-of-record awards under one-time license and product-plus-services arrangements, with no public pricing disclosed. The go-to-market is enterprise field sales direct to military commands, CIOs/CTOs of defense programs, ISR and battle management teams, and Information System Security managers, supported by contract vehicles for rapid procurement. The company has 11 registered product trademarks, an active 2025-2026 product roadmap, and no disclosed funding rounds, M&A activity, or external ownership, signaling an organically funded mid-tier defense prime.
