GINOM is a simulation-based decision support platform that models interdependencies and vulnerabilities across critical infrastructure systems to help organizations manage extreme, multi-sector crises. Combining AI-enhanced analytics with scenario-based simulations, the platform allows utilities, governments, insurers, and infrastructure operators to test responses to events such as cyberattacks, natural disasters, blackouts, and supply disruptions. By analyzing how infrastructure components interact under stress, GINOM identifies potential cascading failures and supports informed decision-making before, during, and after emergencies. It also enables long-term strategic planning by evaluating the system-wide impact of policies, maintenance, or investment decisions, helping stakeholders strengthen resilience and optimize operations.
