Looking for a traineeship or a job in cybersecurity?

Nixu is constantly looking for new talents, who want to set their bet to the 100% legal side of cyber security. We have plenty of other opportunities within our organization both for junior hires and experienced professionals.

Please notify that working on a security industry may require Employer to request a personnel security clearance by the local Security Intelligence Service.


Go to and solve as many individual challenges as you can and write a report on how you achieved the results. Please note, there is no need to solve all the challenges!
