This case study examines Slovenia’s cybersecurity landscape, focusing on technology transfer, information sharing, and cooperation between civil and defence sectors. The research, based on desk analysis, interviews, surveys, and expert validation, finds that while Slovenia has established a solid regulatory and institutional foundation aligned with EU standards, implementation remains uneven. Key challenges include fragmented coordination, insufficient funding, and a shortage of skilled professionals. Nonetheless, strong progress has been achieved in international cooperation, R&D participation, and the development of national capabilities such as SI-CERT and URSIV. The study highlights the need to update the national cybersecurity strategy, enhance technology transfer mechanisms, and strengthen dual-use innovation. It concludes that Slovenia’s resilience depends on sustained political commitment, trust-based collaboration, and the integration of research, industry, and public administration into a coherent cybersecurity ecosystem.
