Aegis AntiCheat

Aegis is an advanced hybrid anti-cheat detection system designed for modern Minecraft servers. It provides the easiest and most robust solution for keeping your server clean and fair — powered by async packet analysis, Folia support, and deep physics validation to catch combat exploits, movement hacks, and network packet abuse.
