Valve Anti-Cheat, abbreviated as VAC, is an anti-cheat solution developed by Valve Corporation as a component of the Steam game development platform.
Those who are VAC Banned cannot enter a VAC-enabled server. However, this only applies to the engine the game uses. For example, if you are banned on Counter-Strike or Half-Life, only games which use the Goldsource engine will be affected. You can still play games and connect to secure servers on games that do not use the same engine. In addition, those who are VAC Banned have all non-purchased items deleted from their backpack.
