Hacking Smart Cities: How to Defend European Critical Infrastructure Roundtable, Simulation, Strategic Dialogue This exclusive event brings together executives, top experts, political decision-makers, industry representatives, and media stakeholders at the intersection of technology, security, infrastructure, and geopolitics. The program provides a high-level forum to assess the accelerating evolution of cyber-physical threats and to discuss strategic approaches to strengthening Europe’s resilience and critical infrastructure. Strategic Focus Europe is undergoing a profound structural transformation. Machines, vehicles, buildings, transportation networks, and supply systems are converging into cyber-physical ecosystems that are interconnected, automated, and increasingly governed by real-time AI. This integrated operational landscape enables unprecedented efficiency and innovation, but also introduces systemic risks that extend far beyond traditional IT and cloud environments. At the center of this shift are connected buildings and smart cities: multilayered environments where energy, data, automation, mobility, and human interaction intersect. Their growing reliance on AI-driven control systems and digital operational layers makes them both strategic assets and strategic vulnerabilities in modern threat scenarios.
