Anti-cheat
Software games use to detect cheats, such as Easy Anti-Cheat, BattlEye, Ricochet and Vanguard.
An anti-cheat looks for cheat software and suspicious behaviour, then flags or bans accounts. Most modern anti-cheats run at kernel level and also collect hardware IDs.
The big ones are Easy Anti-Cheat, BattlEye, Ricochet and Riot Vanguard. Read our anti-cheat guide for how each one works.
