DownloadKey Features
XYREX Guard is the best choice to protect your Hearts of Iron IV lobby
Local host-based protection — runs only on the host machine
The Anti-Cheat runs exclusively on the lobby host's machine — no installation required on other players' devices. Operates independently from the game to minimize risk.
No game-process injection
The Anti-Cheat does not inject code into the game's process and operates safely outside it, avoiding interference with game binaries while reliably monitoring network traffic.
Packet interception and analysis
Intercepts and analyzes Hearts of Iron IV network packets on the host before they reach the game, detecting suspicious data and tampering attempts.
Deep packet analysis with Clausewitz lexer
Packets are parsed with a specialized binary lexer for the Clausewitz engine. Field structures are shown in a nested tree view, allowing deep inspection of every packet field.
Active protection
If the program detects packet spoofing, DLC disabling, or autosave tampering, it can instantly block these actions. Settings allow you to choose the level of automatic protection.
Player monitoring
Shows connected players with nickname, country, IP address, connection port, Steam ID, and counts and severity of warnings, helping to detect suspicious participants rapidly.
Action log
All player actions are stored in a searchable log. You can filter by player and use advanced filters and regular expressions to find specific events and patterns.
Ban system
Supports blocking and banning players by IP, connection port, nickname, or Steam ID — all manageable from the panel.
Automatic blocking
The Anti-Cheat can automatically block suspicious actions—country boosting, lobby changes, controlling other players’ countries, or attempts to crash the server.
Full control over players’ network activity
Our Hearts of Iron IV Anti-Cheat runs on the lobby host's machine and operates separately from the game — it does not inject code into the game's process. It analyzes traffic in real time with a Clausewitz binary lexer, detects suspicious packets, and blocks attempts to disable DLC, change game parameters, or artificially boost a country.
