Immersive Defensive Security is a blue team training platform that places security professionals in hands-on, scenario-based labs designed to build and sharpen defensive cybersecurity skills. The platform covers eight critical risk areas: authentication, physical security, device protection, secure browsing, data handling, security reporting and responsiveness, digital footprint management, and social engineering. Training is organized across four improvement pillars: - Incident Response: Hands-on labs simulating real-world cyber crises to develop swift and accurate response capabilities. - Defense Strategies: Regular cyber defense drills aimed at anticipating and mitigating potential attacks proactively. - Threat Intelligence: Integration of up-to-date cyber threat intelligence into defensive training to address sophisticated threats. - Detection: Labs focused on improving threat detection capabilities. The product is part of the broader Immersive One platform, which combines several components: Immersive Labs (core skill-building), Cyber Range Exercising (team-based scenario simulations), Crisis Sim (leadership-focused decision-making exercises), and Cyber Drills (readiness validation simulations). The platform offers 2,500+ hands-on labs covering foundational skills, advanced threats, secure coding, and more. It is used by businesses, government agencies, and defense organizations globally, with noted customers including HSBC, Microsoft, Pfizer, Goldman Sachs, National Grid, Daimler, and Citi.
