From energy grids to smart factories, critical infrastructures face rising cyber threats that exploit complex, interconnected, andheterogeneous systems. Traditional security approaches often struggle to provide the situational awareness needed for effectiveresilience in these dispersed environments. ResilMesh's primary objective is to strengthen digital resilience by developing a cutting-edge Security Orchestration and Analytics Platform Architecture (SOAPA) toolset. This platform will integrate AI-driven detection algorithms, dynamic risk assessment forecasting, and interoperable security controls to help Computer Security Incident Response Teams (CSIRTs) anticipate attacks and respond more effectively.
