OWASP Global AppSec EU 2026 Vienna

interactive DDoS competition - player on player!

Each round players chooses to be an attacker or defender, matches up with an opponent and configures their attack/defense. The attack traffic is run (speed run), scores are given based on attack traffic stopped vs let through, and legit traffic blocked.

Players gain points each round, and there is an ongoing scoreboard. Leading attacker and defender configs are published too, so defenders and attackers can adapt.

The game is played on a webapp so can be accessed via mobile or laptop.
