About

NPN is a lightweight packet protection plugin designed for modern Minecraft servers.

Instead of functioning as a traditional anticheat, NPN focuses on protecting servers from malformed packets, packet abuse, inventory exploits and protocol manipulation while maintaining high performance and minimal resource usage.

The plugin uses a modular packet security architecture where every detection system has its own packet session, trackers, validators and cancellation logic to improve accuracy and reduce false positives.
