What is Sentry?

Sentry is the ultimate next-generation security mod and plugin for your Minecraft server — giving you real peace of mind so you can focus on building an community instead of fighting off threats. It intelligently blocks hacked clients and malicious mods, stops exploits, prevents bots and VPN abuse, detects cheaters, and logs everything important.

All of this runs smoothly with minimal resource usage, whether you're running a small survival world or a busy public network.

Modules

Check all the 11 modules Sentry currently have.

Fog of War

This module's name comes from the same anticheat method, the "Fog of War". This module allows the possibility of completely blocking and hiding other players from getting information/packets when they are hidden behind a wall or out of sight.

This completely blocks any way of players, even using cheats like Wallhacks/PlayerESP/X-Ray to see and track other players behind blocks.
