418 Intelligence, operating under the brand name FOUR18, develops a virtual cyber work-based learning and gamified crowdsourcing platform called DEF3NSE. The platform is designed to provide hands-on cybersecurity training using real-time, real-world data sourced from live threat feeds and open-source intelligence. The DEF3NSE platform operates through a structured workflow: users plug into real-world trending threats and alerts, perform research on live data, receive real-time coaching from practitioners, hunt and report threats, earn credentials, and participate in a gamified and incentivized environment. Coaching and collaboration are provided by subject matter experts (SMEs) alongside peer and employer team interaction. The platform serves three primary audiences: students seeking to build technical analysis, critical thinking, and teamwork skills for cybersecurity roles; employers looking to access job-ready cyber talent or upskill existing teams; and educational and workforce organizations aiming to improve access to cybersecurity careers. The underlying technology is described as developed from US Intelligence R&D. Partners and clients include educational institutions such as Edmonds College and UMBC, workforce and EdTech organizations including JFF, LCTCS, and the US Department of Homeland Security, as well as cybersecurity firms like rThreat and ISECOM. The company offers resources including case studies and platform overviews covering crowdsourced cybersecurity and upskilling use cases.
