About the Company

Sigma Defense

Software-driven CJADC2 and C5ISR systems

Sigma Defense provides software-driven solutions that improve military communications and decision-making. It specializes in integrating advanced technologies, data analytics, and communication networks to create interoperable systems that share real-time information across all military services and agencies. Its CJADC2 focus means it bridges legacy systems with modern technology to speed access to data and enhance decision-making through sensor analysis and strong network security. The portfolio includes C5ISR, SATCOM, and DevSecOps, and features a Tactical Relay System (a U.S. Government Program of Record) that transports and distributes tactical ISR data. The company uses DevSecOps to enable rapid, secure deployment of capabilities to front-line users, with a team of veterans and technologists developing hardware and software solutions to improve decision quality, speed, and certainty in military operations.
