Organizations face increasing systemic vulnerabilities from reliance on external technology providers and software components. Risks associated with outsourced IT service providers (OSPs), such as cloud hosts, can create a ‘single point of failure,’ causing simultaneous losses across multiple clients. In the banking sector, this growing reliance on cloud computing requires resilience to be integrated into technology from the design phase. Mitigation strategies include implementing software escrow and stressed exit strategies, while emerging technologies like AI and quantum computing necessitate continuous updates to risk management plans. In the industrial sector, particularly in Italy, concentration risks are notable; approximately 30.5% of suppliers have only a single connection to a lead firm, and roughly 76% of active suppliers are micro or small enterprises, which may be more exposed to disruptions. Beyond technical dependencies, organizational fragmentation complicates risk management.
