This public deliverable is part of the COcyber Work Package (WP) 4 "Know-how, good practice sharing, and information transfer activities". COcyber is a two-year initiative supported by the European Commission and European Cybersecurity Competence Centre to foster the collaboration of civilian and defence cybersecurity sectors. The report presents a comparative analysis of cybersecurity technology transfer and information-sharing frameworks across four EU Member States: Lithuania, Spain, Hungary, and Slovenia. Using a mixed-methods approach combining desk research, stakeholder interviews, surveys, and national validation workshops, the study identifies common challenges, best practices, and national divergences in cybersecurity governance, innovation ecosystems, and cross-sectoral collaboration. The findings highlight the importance of harmonised legal frameworks, institutional coordination, and sustained investment in dual-use technologies to strengthen EU-wide cybersecurity resilience and strategic autonomy.
