The evolution of cyber forces in NATO countries


The emergence of cyberspace as a realm of strategic competition has fundamentally transformed the global security environment, necessitating that NATO and its member states continuously reassess the frameworks, doctrines, and capabilities required for effective defence. As cyber threats increase in frequency, complexity, and severity—spanning critical infrastructure sabotage to hybrid disinformation campaigns—NATO allies are expediting the establishment of specialised cyber units within their national armed forces. These advancements address national security requirements and significantly enhance the Alliance’s collective resilience.

This study provides a thorough analysis of cyber force development across all 32 NATO member states, emphasising their distinct methodologies for establishing, organising, and integrating cyber units within their respective military and defence structures. Each nation is evaluated based on its cybersecurity environment, the historical development of its cyber units, and the present organisation and competencies of its cyber forces. The research indicates a robust and escalating trend wherein, although states may initially develop cyber capabilities for national interests, the aggregate impact of these concurrent endeavours substantially bolsters NATO’s collective security framework in cyberspace.

Through this detailed comparative analysis, the paper identifies both common patterns and national distinctions in how cyber forces are conceptualised, funded, and deployed. Despite variations in maturity and structure, from highly advanced commands to newly forming units, every member state is increasingly recognising cyberspace as a domain where a military presence is essential. The study highlights the strategic convergence between national sovereignty in cyber defence and the interdependence required for effective NATO coordination, especially in light of evolving threats from adversarial actors such as the Russian Federation.
