VALORANT Anti-Cheat Sparks Security Concerns

VALORANT Anti-Cheat Sparks Security Concerns

Users on the VALORANT sub-reddit have discovered that, unlike other Anti-Cheat software, “Vanguard” (Riot’s own Anti-Cheat) begins running from the moment you turn on your computer – sparking concerns that Vanguard may be a security risk.


Unlike VALORANT’s competitor CS:GO, Riot chooses the use of two anti-cheat systems – The League of Legends anti-cheat system, and also Vanguard. Some Beta players have expressed concerns surrounding the use of Vanguard as it seemingly begins to run as soon as you turn on your PC, rather than when you open VALORANT.

Thankfully, RiotArkem was available on Reddit to dismiss the concerns and provide some feedback. Below is what he said.

TL;DR Yes we run a driver at system startup, it doesn’t scan anything (unless the game is running), it’s designed to take up as few system resources as possible and it doesn’t communicate to our servers. You can remove it at anytime.

Vanguard contains a driver component called vgk.sys (similar to other anti-cheat systems), it’s the reason why a reboot is required after installing. Vanguard doesn’t consider the computer trusted unless the Vanguard driver is loaded at system startup (this part is less common for anti-cheat systems).
This is good for stopping cheaters because a common way to bypass anti-cheat systems is to load cheats before the anti-cheat system starts and either modify system components to contain the cheat or to have the cheat tamper with the anti-cheat system as it loads. Running the driver at system startup time makes this significantly more difficult.

We’ve tried to be very careful with the security of the driver. We’ve had multiple external security research teams review it for flaws (we don’t want to accidentally decrease the security of the computer like other anti-cheat drivers have done in the past). We’re also following a least-privilege approach to the driver where the driver component does as little as possible preferring to let the non-driver component do the majority of work (also the non-driver component doesn’t run unless the game is running).

The Vanguard driver does not collect or send any information about your computer back to us. Any cheat detection scans will be run by the non-driver component only when the game is running.

The Vanguard driver can be uninstalled at any time (it’ll be “Riot Vanguard” in Add/Remove programs) and the driver component does not collect any information from your computer or communicate over the network at all.
We think this is an important tool in our fight against cheaters but the important part is that we’re here so that players can have a good experience with Valorant and if our security tools do more harm than good we will remove them (and try something else). For now we think a run-at-boot time driver is the right choice.”


As it seems, Vanguard is completely safe and users do not need to worry. Riot currently believes that a Run-At-Startup approach is their best bet. However, Riot is continuously monitoring the situation and will make changes should the need arise.
