<p><b>New page</b></p><div>'''VAC''' ('''Valve Anti-Cheat''') is Valve Corporation's automated anti-cheat system used in [[Counter-Strike 2]] and other Valve games on Steam. It is the primary defense against cheating in CS2.<br />
<br />
== Overview ==<br />
VAC operates as a background process that scans for known cheat signatures on a player's system while they are playing a VAC-secured game. When a cheat is detected, the system issues a permanent, non-negotiable ban that restricts the player's account from playing on VAC-secured servers.<br />
<br />
== How VAC Works ==<br />
<br />
=== Detection ===<br />
* VAC runs silently in the background during gameplay<br />
* Scans for known cheat signatures (memory patterns, injected code, modified files)<br />
* Detection databases are updated regularly with new cheat signatures<br />
* Bans are '''delayed''' — there is typically a waiting period between detection and ban to prevent cheat developers from identifying exactly what triggered the detection<br />
<br />
=== VAC Bans ===<br />
When a VAC ban is issued:<br />
* The player receives a permanent ban on that game<br />
* '''Cannot be reversed''' — Valve's policy is that VAC bans are final<br />
* The ban is visible on the player's Steam profile<br />
* Inventory items become trade-locked and unmarketable<br />
* The player cannot play on VAC-secured servers<br />
* The ban applies to the specific game (not all Steam games)<br />
<br />
== Limitations ==<br />
VAC is a '''signature-based''' system, meaning it detects known cheats:<br />
* New or private cheats may evade detection temporarily<br />
* VAC does not use kernel-level anti-cheat (unlike Vanguard, EAC, etc.)<br />
* Some cheats can remain undetected for months before a ban wave<br />
* VAC does not prevent cheating in real-time — it bans after the fact<br />
<br />
== Overwatch ==<br />
CS:GO introduced the '''Overwatch''' system as a complement to VAC:<br />
* Experienced players review reported match demos<br />
* Reviewers judge whether the reported player was cheating<br />
* Community-driven verdicts result in temporary or permanent bans<br />
* Helps catch cheats that evade automated VAC detection<br />
* Status of Overwatch in CS2 has been evolving since launch<br />
<br />
== VAC Live ==<br />
CS2 introduced '''VAC Live''', an enhanced anti-cheat system:<br />
* Real-time detection during live matches<br />
* Can remove cheating players mid-match<br />
* Detected cheaters are removed and their match impact is nullified<br />
* Represents a significant upgrade from traditional delayed VAC bans<br />
<br />
== Tips for Avoiding False Reports ==<br />
* '''Play on official servers''' — VAC only operates on secured servers<br />
* '''Never use third-party software''' that modifies game memory or files<br />
* '''Keep your system clean''' — Some legitimate software can trigger false positives<br />
* '''Don't share accounts''' — You are responsible for all activity on your account<br />
* '''Use [[Prime Status]]''' — Reduces encounters with cheaters<br />
