If you prefer not to install a kernel-mode anti-cheat, CS2 is one of the few major competitive shooters that does not require one. That holds for Valve's own matchmaking; FACEIT, the optional third-party platform many players use for higher-level matches, installs its own kernel anti-cheat and sets its own firmware requirements, which it has been tightening; check its support pages before you play there.

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 VACnet (machine-learning review of gameplay), VAC Live, 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 policy: its VAC FAQ says bans are permanent and non-negotiable, and that incorrectly issued bans are removed automatically. That last part has been tested in public. In December 2025 Valve said erroneous VAC bans would be removed, in January 2026 it said they had been reversed, and in July 2026 it fixed a bug that let some players avoid being processed by VACnet. VAC bans tend to come in waves after detection updates rather than in real time.
