On 24 April 2026, the Bundeswehr outlined outcomes from Locked Shields, describing it as the largest NATO cyber defense drill with approximately 4,000 participants from 41 countries. The German contingent reported that its Blue Team protected critical infrastructure during complex simulated attacks, emphasizing multinational coordination across technical, legal, and strategic decision-making cells.
The Bundeswehr said teams operated under realistic pressure, sharing threat intelligence and defending diverse networks, including critical services, while red teams executed coordinated intrusions. According to the Bundeswehr, the exercise highlighted cross-border collaboration as central to countering sophisticated cyber threats and validated procedures for crisis communication and incident response.
Providing continuity, the Bundeswehr has previously noted that Locked Shields has been organized as a NATO exercise since 2010, training military and civilian experts to defend critical infrastructure under live-fire cyber conditions. Historical materials from the Bundeswehr also point to the recurring scale of roughly 4,000 participants from 41 nations.
The exercise’s focus on resilience and certification-relevant practices aligned with broader EU efforts to strengthen assurance, as eu_digital_strategy reported during the European Cybersecurity Certification Week in Cyprus in April 2026 (eu_digital_strategy). The drill also took place amid AP News reporting of regular NATO and Russian air encounters over the Baltic region, underscoring the broader deterrence environment in which cyber readiness remains a key pillar.
