Valve Anti-Cheat

Valve Anti-Cheat (VAC) is a security system developed by Valve to detect and prevent cheating in their online games, like Counter-Strike and Dota 2. It works by scanning a player's computer for cheat software or modifications that give unfair advantages. If cheating is detected, VAC can automatically ban the player's account from online play, ensuring a fair gaming environment for others. The system operates quietly in the background, maintaining game integrity without disrupting legitimate gameplay. VAC's goal is to uphold a level playing field and protect the gaming experience for all players.
