The document discusses the ZONeSEC project, which aims to develop an EU-wide framework for securing critical infrastructure across wide areas. It summarizes the results of the project's second pilot demonstration at a water utility company in Romania. The pilot tested the integrated ZONeSEC system's ability to detect physical and cyber threats across multiple locations, using sensors, unmanned aerial vehicles, and other technologies. The system successfully detected intrusions and threats to the water intake and treatment sites and provided a unified view of the situation for operators.
