ENDURANCE established and validated the core strategic, technical, and organisational foundations required to strengthen the resilience of interconnected essential services across Europe. The consortium progressed from requirements definition and architectural design to TRL 5 system prototypes, supported by the structured implementation of pilot activities at European (MACRO), national/regional (MESO), and local (MICRO) levels.
The project approach—combining interoperable data infrastructures, a Trusted Data Space, Digital Twin, Resilience and Risk Intelligence, and stakeholder cooperation—was validated through the first pilot cycle and provides a solid basis for the next phase, which will focus on consolidation, scaling, and operational maturity.
Significant progress has been achieved across all core’s technological pillars:
• Digital Twins for Interconnected Essential Services: ENDURANCE delivered the first operational version of Primary Digital Twins representing interconnected essential services, including energy, water, health, telecommunications, and digital infrastructure. These Digital Twins provide georeferenced, multi-domain ecosystem views underpinned by a harmonised ontology aligned with the CER and NIS2 Directives. Validated capabilities include modelling of CI assets, services, and cross sector dependencies, multi-level visualization (asset, service, sector, ecosystem), integration of resilience indicators and dynamic filtering.
• Trusted EU CER Data Space was implemented and deployed using the DSP TRUE Connector. Core functionalities—dataset registration, catalogue management, identity and access management, secure contract negotiation, and initial real-time data exchange—are operational. The Data Space provides the basis for governed and interoperable data sharing across organisational and sectoral boundaries and is integrated with storage, auditing, and analytical services.
• Risk & Resilience Intelligence and Analytics: ENDURANCE established a Risk and Resilience Intelligence framework integrating multidimensional risk and resilience assessment, interdependency and cascading-effect analysis, and simulation-based “what-if” scenario evaluation. The framework operationalises the 8R Resilience Model through KPIs and composite metrics, including Cross-X indicators and an Ecosystem Resilience Index (ERI), enabling resilience assessment from asset to ecosystem level.
• Secure Data Exchange and Federated Processing: A first set of prototypes for secure data exchange and federated processing were delivered, enabling distributed analytics while preserving data sovereignty. A proportionality-based refinement of the security mechanisms has also been initiated for the next phase to ensure robustness while improving operational efficiency and scalability.
