International Cyber Security Summer School 2026

The International Cyber Security Summer School (ICSSS) is an annual summer school, originally organised by NATO C&I Agency, Europol, Leiden University and Security Delta (HSD). The first edition took place in 2015, starting with 40 students. Given the success, further editions of the Summer School have been hosted, allowing up to 60 students to participate in the program. 

The digital threat is undiminished and constantly changing. Interwoven processes in the digital ecosystem mean that everyone can experience the consequences of a cyber incident, even if they seem remote at first. The consequences of attacks, incidents and security breaches are increasing. There is a growing need for cyber security to be treated as a strategic priority on an individual, organisational and governmental level.

This year's edition will take place from 16 - 21 August. Registration is now open!
