Anti-Cheat Systems Explained: EAC vs BattlEye vs Vanguard
What Are Anti-Cheat Systems?
Anti-cheat software is built into online games to detect and ban players using unauthorized tools. These systems run on your PC alongside the game, scanning for suspicious programs, unusual memory access, and known cheat signatures. The three biggest names in the space are Easy Anti-Cheat (EAC), BattlEye, and Riot Vanguard.
Easy Anti-Cheat (EAC)
EAC is used by games like Fortnite, Apex Legends, Rust, and Dead by Daylight. It runs at the kernel level (deep system access) but only while the game is running. It scans your system for known cheat signatures, monitors memory access patterns, and uses machine learning to flag unusual behavior.
EAC is effective against most software cheats but can be bypassed by hardware-based solutions since it primarily monitors software activity on the gaming PC.
BattlEye
BattlEye protects games like PUBG, Escape from Tarkov, Rainbow Six Siege, and DayZ. It's one of the more aggressive anti-cheat systems — it loads as a kernel driver early in the boot process and actively scans for injected code, suspicious drivers, and unauthorized memory access.
BattlEye is known for fast ban waves and hardware bans. It's more aggressive than EAC but follows a similar approach of monitoring the gaming PC for software-level tampering.
Riot Vanguard
Vanguard is Riot Games' anti-cheat, used in Valorant and League of Legends. It's the most invasive of the three — it runs as a kernel-level service that starts with your computer, not just when the game launches. It monitors your system continuously and blocks suspicious drivers from loading.
Vanguard uses AI-driven behavior analysis, making it the hardest to bypass with traditional software methods. It also enforces strict hardware bans.
Quick Comparison
| Feature | EAC | BattlEye | Vanguard |
|---|---|---|---|
| When it runs | Game only | Boot + Game | Always on |
| Kernel access | Yes | Yes | Yes (persistent) |
| Hardware bans | Yes | Yes | Yes (strict) |
| AI detection | Some | Some | Extensive |
| Popular games | Fortnite, Apex, Rust | Tarkov, PUBG, R6 | Valorant, LoL |
Why DMA Bypasses Most Anti-Cheat
All three of these anti-cheat systems focus on monitoring the gaming PC for suspicious software. DMA operates on a completely separate computer, reading memory through a hardware card. Since no cheat software runs on the gaming machine, these systems have very little to detect.
Combined with custom firmware that disguises the DMA card as a normal device, this makes hardware-based solutions extremely effective against even the most aggressive anti-cheat systems.
