Supported protocols and engines
What the game profile protects — UDP game traffic, A2S query/status, RCON, and voice — and which engine presets are a Game Pro feature.

The game profile protects the UDP traffic your game or voice server lives on. This page lists what is covered and where the per-engine presets of Game Pro fit in.
What the game profile protects
| Traffic | Protocol | What the profile does |
|---|---|---|
| Game traffic | UDP | Per-player token buckets absorb floods at line rate |
| Query / status | A2S | Flood shielding that keeps server-browser listing working |
| Remote admin | RCON | Rate-limits abuse without locking out real admins |
| Voice | UDP voice traffic | The same line-rate flood mitigation as game traffic |
The base Game edition protects any UDP-based server with this generic tuned profile — you do not need an engine-specific preset to be covered.
Engine presets are a Game Pro feature
Game Pro adds per-engine detection profiles with presets for Source, FiveM, Minecraft, and Rust. These match detection thresholds to each engine's normal traffic shape, which matters when you run a public server whose patterns attackers study. See Game vs Game Pro for the full comparison.
