European Cyber Security Challenge

The European Cyber Security Challenge (ECSC) is an annual event that brings together young cybersecurity talents from across Europe to compete in a series of challenges. The ECSC is an initiative by the European Union Agency for Cybersecurity (ENISA) and is hosted by a different country each year. The competition aims to raise awareness of cybersecurity and to connect high potentials with industry leading organizations.

Each participating country selects a national team of 10 players to represent them at the ECSC. The teams compete in a series of challenges that test their skills in various cybersecurity domains. The challenges are designed to simulate real-world scenarios and require participants to demonstrate their technical knowledge, problem-solving skills, and teamwork abilities.

ECSC23 in Norway hosted 29 teams from EU Member States and European Free Trade Association (EFTA) countries and 5 guest teams from all over the world.

The ECSC2024 will take place in Torino, Italy as from 08 until 12 October. Luxembourg is participating since 2019. We count on you to improve the LU score in 2024!
