Player vs Player

Arena

Build your network, defend it, and steal flags from other players.

FlagHack logo

Enter a gamified cybersecurity arena where every player builds and defends their own network. Attack other players' networks, find weak services, steal flags, and protect your own infrastructure from incoming attacks. Arena chat, faction pressure, leaderboards, and live competition turn practice into a social hacking experience.
