Our applied security contest (also called CTF as in "Capture The Flag") is the world's biggest on-site: it opposes 80 teams of 8 people trying to obtain the most points by capturing flags.

Those flags typically are secret messages hidden in different challenges.

The Challenges will be available to teams through a web portal on their own private contest network, they are not authorized to attack each other (it's not a red/blue team type of contest), they compete to have the most points on the leaderboard.
