Valve Anti-Cheat or VAC for short was initially realeased in 2002 for Counter-Strike and is standard for all multiplayer GOLDSrc and Source 1 games. Currently Counter-Strike: Global Offensive is the only Source game with an updated version of VAC, using VACnet.
Cheater left the game (VAC banned from secure servers)
