Launched under European Defence Industrial Development Programme in December 2021, the project “Cyber Rapid Response Toolbox for Defence Use” (CYBER4DE) takes on the challenge to develop an easily deployable, modular, and scalable cyber rapid response toolbox to manage cyber incidents in different complex national and international scenarios. The project also aims to enhance processes and practices of Cyber Rapid Response Teams (CRRTs) under the PESCO framework for a faster uptake of the new tools and for increased effectiveness in the operating domain. The CYBER4DE industrial consortium combines large enterprises, mid-caps, and SMEs from Lithuania (Baltic Institute of Advanced Technology (coordinator), NRD Cyber Security), Croatia (Infigo IS, Poslovna Inteligencija), Estonia (Talgen), France (Airbus Cybersecurity SAS, Thales Six GTS), Italy (Leonardo), Poland (Asseco Poland), and Romania (METRA). This project has received funding from the European Defence Industrial Development Programme (EDIDP) under grant agreement no. EDIDP-CSAMN-EDICT-2020-76-CYBER4DE.
