Counter-Strike 2 uses Valve Anti-Cheat (VAC), Valve's conventional user-mode anti-cheat. VAC has no kernel driver, no always-on resident process, and no boot-time component. Detection happens server-side and via user-mode pattern checks during a match. Compared to kernel anti-cheats, VAC is less aggressive about catching sophisticated cheats; Valve supplements it with VAC Live (statistical pattern detection over many matches), VAC Net (machine learning), and Trust Factor for matchmaking. The trade-off is real and well-known: VAC trusts the user-mode boundary in exchange for asking less of the player's system.

Valve has run VAC since 2002; the system is documented in Valve's Counter-Strike support pages and the Steam Subscriber Agreement. VAC has been criticized for catching fewer cheats than kernel anti-cheats but praised for the lower system access it requires. Valve has historically been transparent about ban policies (permanent, cross-account by hardware fingerprint) and conservative about false positives, with the trade-off that VAC bans tend to come in waves after detection updates rather than in real time.
