Is Riot Vanguard Spyware? The Truth Behind the Kernel Controversy

Are you worried about your privacy while playing Valorant? Riot Vanguard, the anti-cheat software for Valorant, has sparked heated debates online. This blog breaks down how Vanguard works, its risks, and whether it’s truly spyware.

Keep reading to uncover the truth behind the kernel controversy.

What is Riot Vanguard?

Riot Vanguard is the anti-cheat system developed by Riot Games for their popular first-person shooter, Valorant. Unlike most anti-cheat tools, Vanguard operates at the kernel level of the Windows operating system, giving it deep access to your computer’s core functions.

This means it runs in Ring 0, a privileged space usually reserved for critical system processes like drivers and security software.

Vanguard works around the clock, even when Valorant isn’t running. It monitors for cheating behaviors and unauthorized modifications that could give players an unfair edge. Some critics have called it a “rootkit” due to its aggressive approach and constant presence on your system.

Despite concerns, Riot Games has defended its design, even offering a $100,000 bounty to anyone who can prove a remote exploit through Vanguard.

Owned by Tencent, Riot Games has faced scrutiny over privacy risks tied to Vanguard’s data collection capabilities. The debate continues as players weigh its effectiveness against potential vulnerabilities and performance issues on their systems.

How Vanguard Works

Riot Vanguard operates at the kernel level, giving it deep access to your system’s core functions. This allows it to monitor processes in real-time, flagging suspicious activity linked to cheating software.

It doesn’t just scan game files—it keeps an eye on everything running in the background, making sure cheaters can’t hide their tricks. Think of it like a bouncer with X-ray vision, spotting troublemakers before they even step inside.

Kernel-Level Access Explained

Vanguard’s kernel-mode driver runs at startup, giving it deep access to your system. This level of access lets it monitor running processes, open files, and even network traffic.

Think of it as a security guard with keys to every room in the building. It’s not just watching the game client—it’s scanning everything to catch cheaters before they can exploit vulnerabilities.

Kernel-level anti-cheat systems like Vanguard operate independently of Valorant itself. They start when Windows boots up, keeping an eye on other drivers and software. While this helps block cheating tools effectively, it also raises questions about privacy risks and potential conflicts with other programs.

Some users worry about compatibility issues or performance hits, especially if their system isn’t built for gaming alone.

Data Monitoring Capabilities

Vanguard’s data monitoring capabilities are built around its kernel-mode driver, which operates with high-level system privileges. This allows it to scan for unauthorized modifications and cheating software in real-time.

The system uses TPM 2.0 to validate certificate signing, adding an extra layer of security. While this helps prevent cheats, it also raises privacy concerns due to the depth of access.

Encrypted data is sent to Riot Games servers, but what exactly gets transmitted remains unclear. Some users worry about potential misuse or vulnerabilities that could expose sensitive information.

For those concerned about privacy, using a dedicated gaming system or disabling Vanguard when not playing might be worth considering. If you’re starting fresh, a level 30 League account can save time while avoiding unnecessary risks tied to anti-cheat systems like Vanguard.

Concerns About Vanguard

Vanguard’s kernel-level access raises eyebrows, as it digs deep into your system like a nosy neighbor peeking through windows. Critics worry about privacy risks, potential exploits, and whether it plays nice with other software—imagine two chefs fighting over the same kitchen.

Privacy Risks

Vanguard’s kernel-level access raises serious privacy concerns. It operates deep within your system, monitoring activity constantly. This level of access means it can see almost everything happening on your computer, even when you’re not gaming.

Critics argue this creates a backdoor for potential misuse or exploitation by bad actors.

Riot Games claims Vanguard only collects data needed for cheat detection, but their lack of transparency fuels skepticism. The EULA also limits users from taking legal action against Riot, leaving little recourse if issues arise.

Adding to the unease is Tencent’s ownership of Riot Games, sparking fears about data being shared with Chinese state-owned enterprises. While Riot offers a bug bounty program to address security vulnerabilities, many feel it doesn’t tackle the broader risks tied to user privacy and online security.

Potential Vulnerabilities

Vanguard’s kernel-level access is a double-edged sword. While it helps catch cheaters, it also opens the door for potential exploits. Running at such a deep system level means any vulnerability in Vanguard could be abused by hackers to gain control over your PC.

Think of it like leaving your front door unlocked—it’s convenient for you but risky if someone with bad intentions shows up.

The anti-cheat software runs continuously in the background, even when you’re not gaming. This constant operation increases the attack surface, making it easier for malicious actors to find and exploit weaknesses.

If a hacker finds a way in, they could potentially steal sensitive data or cause serious damage to your system. Riot Games claims data transmission is encrypted, but encryption isn’t foolproof—interception risks still exist.

For example, vulnerabilities similar to those found in Lenovo’s LSE rootkit have raised alarms about Vanguard being misused as spyware or malware. The forced arbitration clause in Riot’s EULA further complicates things, limiting users’ ability to seek legal recourse if something goes wrong.

These concerns highlight why some gamers are wary of giving Vanguard so much power over their systems.

System Conflicts and Performance Issues

Moving from potential vulnerabilities, system conflicts and performance issues have been a major headache for players. Nick ‘LS’ De Cesare, a well-known content creator, reported that Vanguard bricked two of his PCs.

Some users faced extreme measures like removing the CMOS battery just to get their systems running again. Error messages like “Vanguard error 1067” became common after updates, leaving players frustrated.

Compatibility problems with certain hardware and software added fuel to the fire. Players noticed game performance drops, crashes, and even full system freezes. These issues sparked heated debates on online forums like Reddit, where users shared their troubleshooting nightmares.

Critics argue that Vanguard’s kernel-level access might be too intrusive for its own good, causing more harm than it prevents in anti-cheating efforts.

Riot Games’ Response to Spyware Allegations

Riot Games has been clear about Vanguard’s purpose. They state it only collects data needed to detect cheating, nothing more. The anti-cheat system was built with input from their Anti-Cheat, Security, and Data Privacy teams.

This ensures a balance between stopping cheaters and protecting user privacy.

The company also points out that Vanguard has undergone reviews by both internal and external security experts. They even run a Bug Bounty program, rewarding researchers who find vulnerabilities in the system.

Riot emphasizes that Vanguard doesn’t collect personal information beyond what’s necessary for game operation compared to DOTA 2, which uses a different approach to anti-cheat measures.

While concerns about kernel-level access remain, Riot insists the system is designed with online privacy and data security in mind.

Mitigating Risks When Using Vanguard

To reduce risks with Vanguard, you can manually disable it when not gaming. Using a separate system just for gaming also keeps your main computer safe from potential issues.

1. Exit Vanguard via System Tray: Right-click the Vanguard icon in the system tray. Select “Exit Vanguard” to disable it. This stops the anti-cheat from running until the next system restart.
2. Restart to Re-enable: After disabling, you must restart your computer to reactivate Vanguard. It won’t run again until the system boots up with it enabled.
3. Uninstall Vanguard Manually: Uninstalling VALORANT doesn’t remove Vanguard. Use Command Prompt (CMD) to delete it. Open CMD as an administrator, then type the uninstall command provided by Riot Games.
4. Use Dedicated Gaming Systems: Some players disable Vanguard on their primary PC and use a separate system for gaming. This reduces potential conflicts with other software or performance issues.
5. Check for Conflicts: Disabling Vanguard can help troubleshoot system conflicts. If your PC runs smoother without it, you might want to keep it off when not gaming.
6. Reinstall if Needed: If you decide to re-enable Vanguard later, reinstall it through the VALORANT client. The process is quick, but a restart is still required.
7. Understand the Trade-offs: Disabling Vanguard means you can’t play VALORANT until it’s back on. The kernel-level access it uses is designed to prevent cheating, but some users question its necessity.
8. Follow Community Tips: Many players share their experiences online. Some recommend disabling Vanguard when not gaming to avoid unnecessary background processes.
9. Stay Updated: Riot Games occasionally updates Vanguard. Check their official guides for the latest instructions on disabling or reinstalling it.
10. Weigh Privacy Concerns: If you’re worried about data monitoring, disabling Vanguard might ease your mind. Just know that playing VALORANT without it isn’t an option.

Disabling Vanguard gives users more control over their systems. Whether for privacy, performance, or personal preference, the choice is yours.

Using Dedicated Gaming Systems

Using a dedicated gaming system is one way to tackle privacy concerns tied to Riot Vanguard. By installing Valorant on a separate hard drive or SSD, you can isolate the anti-cheat software from your main system.

This setup reduces the risk of personal data exposure while still letting you enjoy fair gameplay.

Some gamers prefer this approach, especially those wary of kernel-level access and potential security vulnerabilities. A dedicated system keeps your primary machine free from conflicts or performance issues caused by Vanguard’s deep integration.

It’s a practical workaround for players who value both privacy and cheat-free matches without compromising their main setup.

Community Opinions and Debate

The debate over Riot Vanguard’s kernel-level access has sparked heated discussions across platforms like Reddit and NeoGAF. Critics, including WestJett in his December 29, 2024 video titled “Valorant Is Spyware,” argue that the anti-cheat system crosses privacy boundaries.

Many users demand transparency, pushing for Riot Games to release Vanguard’s source code. Others point out that similar anti-cheat programs use comparable methods, making the criticism feel one-sided.

On the flip side, some players defend Vanguard as a necessary evil to combat cheating effectively. The $100,000 bounty offered by Riot Games for proving remote PC compromise via Vanguard adds weight to their claims of security.

Still, concerns linger about Tencent’s ownership and how data might be handled under China’s cybersecurity laws. The forced arbitration clause in the EULA further fuels distrust, limiting legal recourse if issues arise.

Whether you see it as a rootkit or a guardian against cheaters depends on where you stand in this ongoing tug-of-war between privacy and fair play.
