The watchdog software a multiplayer game uses to catch cheaters. Vanguard (Valorant), Easy Anti-Cheat, and BattlEye are the common ones.
More detail
To spot cheats they watch for anything tampering with the game or the system, which is why injectors, kernel tweak tools, and some driver hacks get accounts banned. Several require Secure Boot or TPM to be on. The safe rule: if a "tweak" touches game memory, timers, or drivers in a non-standard way, assume anti-cheat risk until proven otherwise.
