Immersive Crisis Sim is a cyber crisis simulation platform that enables organizations to run dynamic, scenario-based exercises designed to test and evaluate decision-making, leadership coordination, and cross-functional team response during simulated cyber incidents. Unlike static tabletop exercises, the platform uses AI-driven actors and dynamic crisis feeds to replicate the pressure and complexity of real-world breaches. Scenarios involve various threat actors and attack vectors, and can be selected from a pre-built catalog or generated on demand using an AI-powered scenario generator. The platform evaluates performance across multiple dimensions, including decision latency, accuracy, coordination between technical and non-technical stakeholders, and communication effectiveness. Role-specific analysis provides insights into individual and team contributions during a crisis. Results are benchmarked against industry frameworks including NIST, ISO, and DORA, allowing organizations to validate their readiness against recognized standards. Actionable metrics quantify financial, operational, and reputational impacts of decisions made during simulations. Crisis Sim is part of the broader Immersive One platform, which covers cyber resilience measurement across technical skills and organizational preparedness.
