Riot Vanguard: Anti-Cheat for Valorant

Riot Vanguard is the proprietary anti-cheat system that Valorant requires. Developed by Riot Games to protect competitive integrity, Vanguard uses a kernel-level driver and a background service to detect and block cheating software. It installs alongside Valorant and stays active while the game runs, so it is a required component for access to matchmaking and ranked modes.

How Riot Vanguard Works

Vanguard pairs a kernel driver with a user-mode client to monitor system processes and identify unauthorized modifications, overlays, or injected code that could give players an unfair advantage. Operating at the kernel level gives it greater visibility into system activity than user-mode-only anti-cheat tools, which allows Riot to respond to more sophisticated cheating methods.

Key Features

• Kernel-level driver and background service: Provides system-level monitoring to identify advanced cheats.
• Automatic updates: Vanguard updates alongside Valorant to address new threats and improve stability.
• Service-driven enforcement: A background process (vgc) must be active before Valorant can launch.
• Mandatory installation: Valorant does not run without Vanguard installed and the vgc service enabled.

Benefits and Trade-offs

• Benefits:
  • Strong deterrent against cheating, supporting fair play and competitive integrity.
  • Regular updates shorten the period during which new exploits remain effective.
  • Built-in enforcement makes it harder to bypass anti-cheat protections.
• Trade-offs:
  • Kernel-level access requires a high level of trust in Riot's software and security practices.
  • Compatibility issues, driver conflicts, or performance effects may occur 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

Typical problems include the game failing to launch because the vgc service is stopped, driver signing enforcement preventing Vanguard's driver from loading, and specific error codes during startup. Riot provides dedicated guidance for Vanguard Pre-Check, Memory Integrity (HVCI/VBS) settings, and error codes such as VAN9002.

Troubleshooting Checklist

1. Restart your PC: many vgc and driver-loading issues clear after a full reboot.
2. Check the vgc service: confirm that the Vanguard service is running and set to start automatically before launching Valorant.
3. Run the Vanguard Pre-Check and review Memory Integrity (HVCI/VBS) settings if the system fails validation.
4. Reinstall Valorant through Add or Remove Programs if Vanguard is corrupted or missing.
5. Verify driver signing and Windows updates, since unsigned driver policies or pending OS updates can interfere with Vanguard loading.
6. Temporarily disable conflicting software, as some antivirus or system modification tools block kernel drivers. Adjust their settings or add exceptions where appropriate.
7. Follow the specific fix for each error code, such as code 57 or other launch failures, rather than applying general changes.

Privacy, Security, and Best Practices

Because Vanguard runs at the kernel level, players should consider its privacy and security implications. Riot describes the driver as limited to cheat detection and to processes relevant to gameplay. Recommended practices include keeping Windows and drivers updated, installing Vanguard and Valorant from official sources, and reviewing Riot's support documentation before changing system security settings.

Who Should Install Riot Vanguard?

Any player who wants full access to Valorant, including ranked play, must install Riot Vanguard. Competitive players and communities that prioritize fair play benefit most from its 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 through the Windows Apps & Features control panel if Vanguard does not install or the vgc service fails to run.
3. Use Riot's official installation and technical help articles for step-by-step guidance on launch errors and service issues.
4. When troubleshooting, record error codes and check Riot's support resources before making system-wide changes.
