In a live cyber-defence exercise made up of 3,000 virtual systems and 2,500 attacks, the winner of this year’s Locked Shields exercise is the Czech Republic. Estonia and the USA share joint second and third place.

The annual defense exercise helps train the security experts who protect our national IT systems on a daily basis.

Every year, teams are put under extreme pressure to maintain the networks and services of a fictional country. To stay up to date with the current threat landscape, Locked Shields focuses on realistic and cutting-edge technologies, networks and attack methods in the scenarios it deals.

Locked Shields is organized by Nato in cooperation with the Estonian Defence Forces, the Finnish Defence Forces, the Swedish Defence University, the British Army, the United States European Command, Air Operations COE and Tallinn University of Technology.

In terms of the main areas in the exercise, the USA team scored the highest in the legal game of the exercise, Germany won the forensic challenges and the team from the UK achieved the highest scores in handling the strategic communication challenges.

Arre Reintam, the Technical Exercise Director at NATO CCD COE stated “The winning team demonstrated that good tactics and stable performance in all categories can lead to best overall scores in the end. The experts of the Czech team also performed very well in the strategic track that was a new addition this year.”
