CYBERUNITY aims to strengthen Europe’s cybersecurity resilience by building the first interoperable cyber range infrastructure in Europe. The project brings together existing cyber ranges from consortium partners and develops open interoperability specifications to enable a unified, cross-border cyber range community. Through this approach, CYBERUNITY introduces the concept of Cyber-Range-as-a-Service (CRaaS) and establishes a shared Knowledge Repository for cyber range technologies. The project deploys a secure, privacy-compliant framework that supports cross-organisation and cross-border cybersecurity training and testing, demonstrated through real-world scenarios in critical sectors. By the end of the project, CYBERUNITY is expected to benefit approximately 2,000 cyber defenders across Europe, including users from regions with limited access to cyber range facilities.
