The world\u2019s largest live-fire cyber defense exercise, Locked Shields 2026, concluded on Friday after bringing together more than 4,000 participants from 41 nations.\u00a0<\/strong><\/p>\n

Organized by the NATO Cooperative Cyber Defence Centre of Excellence (CCDCOE) in Tallinn, Estonia, the event simulated intense real-time cyberattacks against critical infrastructure and military systems, testing defenders\u2019 ability to maintain essential services under pressure.<\/p>\n

The number of participants was the same as in 2025.<\/p>\n

Teams were tasked with protecting air defense, e-voting platforms, and other critical infrastructure. In addition to technical skills, Locked Shields tests the ability to deal with disinformation and political pressure.<\/p>\n

According to T\u00f5nis Saar, Director of the NATO CCDCOE, participants demonstrated strong capabilities in detecting and responding to malicious activity. Saar emphasized the need to translate exercise lessons into real-world readiness, particularly as AI continues to reshape both cyber defense and attack capabilities.<\/p>\n

Sixteen multinational teams competed in the exercise. The three highest-scoring joint teams, listed in no particular order, were France and Sweden; Latvia and Singapore; and Germany, Austria, Luxembourg, and Switzerland.\u00a0<\/p>\n

Exercise Director Dan Ungureanu underscored the event\u2019s core objective: enhancing international collaboration, building trust, and developing a shared understanding of cyberspace resilience.\u00a0<\/p>\n

Locked Shields has evolved significantly over the past 16 years. When the first exercise was held in 2010, only four nations and 60 individuals participated.<\/p>\n
