Second Front Systems is a public-benefit software company that helps commercial software vendors and government teams deploy applications into classified and regulated national security environments. Its flagship platform, Game Warden, is a continuous-authorization (cATO) DevSecOps environment that handles the security, compliance, and accreditation burden, dramatically shortening the time it takes to get modern software into the hands of warfighters and agencies. By abstracting away the complexity of Authority to Operate (ATO) processes and providing a hardened, accredited hosting environment, Second Front lets defense and intelligence customers adopt commercial and AI software quickly and securely. Founded by veterans and technologists, the company has become a key enabler of govtech and defense software modernization. It raised a $70M Series C in September 2024 led by Salesforce Ventures, bringing total funding above $150M.
