Do you play VALORANT or League of Legends? Have you ever wondered about that little red icon in your system tray or the background process quietly running on your computer even when you're not gaming? That, my friend, is Riot Vanguard, Riot Games' highly specialized anti-cheat system. While its presence is crucial for maintaining fair play, a common question often pops up: "How many GBs is Riot Vanguard, and what exactly is it doing on my PC?"
Let's dive deep into the fascinating (and sometimes controversial) world of Riot Vanguard and uncover its footprint on your system!
Unpacking the Anti-Cheat: How Many GBs Is Riot Vanguard?
One of the most frequently asked questions about Riot Vanguard revolves around its size. It's a valid concern, especially for gamers with limited storage space. So, let's get straight to the point:
Riot Vanguard itself is surprisingly small. While it's often associated with the larger game installations like VALORANT, Vanguard's core files are generally in the megabytes (MBs), not gigabytes (GBs).
For VALORANT players: The entire VALORANT game, including Riot Vanguard, typically ranges from 28.5 GB to 32 GB for a full installation. Of this, Riot Vanguard itself usually takes up a mere 37 MB to 200 MB depending on the reports and included log files.
For League of Legends players: Since Vanguard was more recently integrated into League of Legends, its size remains similarly small, typically within the MBs range, as it's primarily a background service.
Important Note: While Vanguard itself is small, it's crucial to remember that it's designed to work hand-in-hand with Riot's games. So, when considering the overall storage impact, you need to account for the game itself.

Why is it So Small? Understanding Vanguard's Nature
You might be thinking, "How can an anti-cheat system be so small if it's so powerful?" Here's the breakdown:
Kernel-Level Operation: Riot Vanguard operates at a kernel-level on your PC. This means it has deep access to your system, allowing it to detect cheating software at a fundamental level. This type of operation doesn't require a large footprint in terms of raw file size but rather requires low-level system permissions.
Lean and Mean: Riot Games designed Vanguard to be efficient. Its primary function is to monitor and detect, not to store vast amounts of data or intricate graphical assets. It's more about the code and detection algorithms than large files.
Continuous Updates: While the core size remains small, Vanguard is constantly updated to counter new cheating methods. These updates are usually pushed in small increments, minimizing any significant increase in its overall size.
Step-by-Step Guide: Understanding Riot Vanguard's Presence
Ready to understand what Riot Vanguard does on your system? Let's walk through it!
Step 1: Engage with Your System's Heartbeat – The Task Manager!
Before we get into the technicalities, let's start with something you can do right now. Open your Task Manager (press Ctrl + Shift + Esc or right-click your taskbar and select "Task Manager").
Tip: Reading in chunks improves focus.
Do you see any processes related to "Riot Vanguard" or "vgc.exe" running?
Even if you're not playing a Riot game, you might still see it. This is normal, as Vanguard is designed to run persistently to ensure a fair play environment.
Seeing it there might spark some questions, and that's exactly what we're going to address!
Step 2: What is Riot Vanguard, Really? The Core Concept
Riot Vanguard is a kernel-level anti-cheat software developed by Riot Games. It was initially released with VALORANT in April 2020 and later integrated into League of Legends in April 2024.
Sub-heading: Why Kernel-Level?
This is where it gets a bit technical, but it's crucial to understand. Most anti-cheat systems operate at a "user level," which means they run like regular applications. However, advanced cheats can often bypass these systems by operating at a lower, more privileged level of your operating system – the "kernel level."
Kernel Mode (Ring 0): This is the most privileged mode of operation for a computer's CPU. The operating system kernel and device drivers run in this mode, having direct access to hardware and all system resources.
User Mode (Ring 3): This is where most applications run. They have limited access to system resources and hardware, relying on the kernel to perform privileged operations.
By operating at the kernel level, Riot Vanguard aims to detect and prevent cheats that also attempt to operate at this deep system level, offering a more robust defense against sophisticated cheating.
Step 3: The Dual Components of Riot Vanguard
Riot Vanguard isn't just one monolithic program. It consists of two main components:
The Client (User-Mode Component): This part of Vanguard runs in user mode and handles the more visible aspects, such as communicating with Riot's servers, displaying error messages, and managing the overall anti-cheat process.
The Kernel-Mode Driver (vgc.sys): This is the core of Vanguard's anti-cheat capabilities. It loads when your computer starts up and runs with high privileges. This driver actively monitors your system for suspicious activity that could indicate cheating, such as unauthorized modifications to game files, memory manipulation, or the injection of malicious code.
Sub-heading: Always On? The Persistent Nature
Yes, Vanguard's kernel-mode driver is designed to run persistently in the background, even when you're not playing a Riot game. This "always-on" approach is a key part of its effectiveness. It allows Vanguard to detect cheats that might try to load before a game even launches or attempts to modify your system in ways that could facilitate cheating later.
Tip: Read at your natural pace.
Step 4: What Does Riot Vanguard Actually Do?
Beyond its low-level operation, what are Vanguard's specific actions?
Cheat Detection: This is its primary purpose. Vanguard constantly scans for known cheat signatures, analyzes player behavior patterns, and identifies attempts to manipulate the game client or system memory.
Prevention: If a cheat is detected, Vanguard can take various actions, from preventing the game from launching to issuing temporary or permanent bans. In severe cases, it can even result in hardware bans, preventing cheaters from simply creating new accounts.
System Integrity Checks: Vanguard helps ensure the integrity of your system while playing Riot Games, looking for vulnerabilities that could be exploited by cheaters.
Step 5: Addressing Concerns: Privacy and Performance
The kernel-level nature and persistent operation of Riot Vanguard have led to discussions regarding privacy and system performance.

Sub-heading: Privacy Considerations
Data Collection: Riot Games states that Vanguard is designed to collect only the data necessary for anti-cheat purposes. They emphasize compliance with regional data privacy laws like GDPR.
Transparency: Riot has provided explanations about how Vanguard works and why it requires deep system access. However, the nature of kernel-level access inherently raises privacy questions for some users.
Sub-heading: Performance Impact
Minimal Impact: For most modern systems, the performance impact of Riot Vanguard is designed to be minimal. It's optimized to run efficiently in the background without significantly affecting game performance or overall system responsiveness.
Compatibility Issues: In rare cases, Vanguard might conflict with other software or drivers, leading to performance issues or system instability. Riot Games actively works to address these conflicts through updates. If you encounter issues, contacting Riot Support is recommended.
Step 6: Managing Riot Vanguard: What You Can and Cannot Do
While Vanguard is essential for playing Riot's games, there are some aspects you should know about its management.
Required for Play: You cannot play VALORANT or League of Legends without Riot Vanguard actively running. If you close it or try to bypass it, the game will not launch.
Exiting Vanguard: You can manually exit Vanguard from your system tray (the small icons near your clock). However, if you want to play a Riot game, you'll need to restart your computer for Vanguard to re-enable itself, or restart the Riot Client which will prompt Vanguard to restart.
Uninstalling Vanguard: Uninstalling VALORANT or League of Legends does not automatically uninstall Riot Vanguard. Vanguard must be uninstalled separately. This is a deliberate design choice to prevent cheaters from easily disabling the anti-cheat.
