Riot Vanguard: Editor's Review of Valorant’s Anti-Cheat

Riot Vanguard is the proprietary anti-cheat system required to run Valorant. Built by Riot Games to protect competitive integrity, Vanguard uses kernel-level drivers and a background service to detect and block cheating software. It is installed alongside Valorant and remains active whenever the game is running, making it a non-optional component for players who want access to Valorant’s matchmaking and ranked modes.

How Riot Vanguard Works

Vanguard combines a kernel driver and a user-mode client to monitor system processes and detect unauthorized modifications, overlays, or injected code that could confer unfair advantages. The kernel-level approach provides deeper visibility into system activity than user-only anti-cheat solutions, allowing Riot to respond quickly to sophisticated cheating techniques.

Key Features

• Kernel-level driver and background service: Provides deep system monitoring to identify advanced cheats.
• Automatic updates: Vanguard updates alongside Valorant to address new threat vectors and improve stability.
• Service-driven enforcement: A background process (vgc) ensures the anti-cheat is active before allowing the game to launch.
• Mandatory installation: Valorant will not run without Vanguard installed and the vgc service enabled.

Benefits and Trade-offs

• Benefits:
• • Strong deterrent against cheating, protecting fair play and competitive integrity.
  • Proactive updates reduce the window of exposure to new exploits.
  • Integrated enforcement prevents players from bypassing anti-cheat protections.
• Trade-offs:
• • Kernel-level access requires a high degree of trust in Riot’s software and security practices.
  • Some systems may experience compatibility issues, driver conflicts, or performance impacts depending on hardware and third-party software.
  • Troubleshooting can involve OS-level settings, driver signing, or conflicts with other security tools.

Common Installation and Technical Issues

Riot’s support resources cover a range of installation and technical problems. Typical issues include the game failing to launch due to the vgc service being stopped, driver signing enforcement preventing Vanguard’s driver from loading, or specific error codes during startup.

Troubleshooting Checklist

1. Restart your PC: many vgc and driver-loading issues clear after a full reboot.
2. Check the vgc service: ensure the Vanguard service is running and set to start automatically before launching Valorant.
3. Run the installer as administrator: reinstall Valorant via Add or Remove Programs if Vanguard is corrupted or missing.
4. Verify driver signing and Windows updates: unsigned driver policies or pending OS updates can interfere with Vanguard loading.
5. Disable conflicting software temporarily: some antivirus or system modification tools block kernel drivers—adjust settings or add exceptions per Riot’s guidance.
6. Follow supported fixes for specific error codes: consult Riot’s installation and technical help articles for targeted steps on common errors like code 57 or other launch failures.

Privacy, Security, and Best Practices

Because Vanguard runs at the kernel level, players should be aware of the privacy and security implications. Riot states the driver is solely for cheat detection and is limited to processes relevant to gameplay. Best practices include keeping Windows and drivers updated, installing Vanguard and Valorant from official sources, and reviewing Riot’s support articles when adjusting system security settings.

Who Should Install Riot Vanguard?

Any player who wants to access Valorant’s full feature set, including ranked play, must install Riot Vanguard. Competitive players and communities that prioritize fair play will benefit from Vanguard’s protections, while users with strict privacy or compatibility concerns should weigh the trade-offs before installing.

User Tips for Stable Play

1. Keep Windows and GPU drivers current to minimize compatibility issues with kernel-level software.
2. Reinstall Valorant via the Windows Apps & Features control panel if Vanguard does not install or the vgc service fails to run.
3. Consult Riot’s official support installation and technical help articles for step-by-step guidance on common launch errors and service issues.
4. When troubleshooting, capture error codes and check Riot’s support portal before making system-wide changes.
