Fix Valorant VAN 9001: Resolving Valorant Connection Error VAN 9001 (Valorant)

The Valorant VAN 9001 error is a common technical hurdle that primarily affects users running the game on Windows 11. This error is generated by Riot Vanguard, the game’s kernel-level anti-cheat system, when it detects that essential hardware security features are not active. As a Senior IT Technician, I recommend addressing this at the firmware level to ensure long-term stability and compliance with Riot’s security protocols.

🧐 Causes

• Secure Boot is currently disabled in the system’s BIOS/UEFI settings.
• Trusted Platform Module (TPM) 2.0 is either disabled or not present on the motherboard.
• The system is running in Legacy BIOS mode instead of UEFI mode.
• Exploit Protection settings in Windows are interfering with the Vanguard initialization process.

🔧 Fixes

• Enable Secure Boot: Restart your workstation and tap the BIOS key (usually Del, F2, or F12) during startup. Locate the “Boot” or “Security” tab and change the Secure Boot status to “Enabled.” Note that you may need to set the Boot Mode to “UEFI” first.
• Enable TPM 2.0: While still in the BIOS, search for “Trusted Computing,” “fTPM,” or “PTT.” Ensure this setting is toggled to “Enabled.” This allows Windows to utilize the hardware-based security required by Vanguard.
• Disable CSM (Compatibility Support Module): If your BIOS has CSM enabled, it may prevent Secure Boot from functioning. Disable CSM to force the system into a pure UEFI environment.
• Adjust Windows Exploit Protection: Open the Windows Start menu, type “Exploit protection,” and open the system settings. Ensure that “Control flow guard (CFG)” is turned on, as certain Vanguard versions require this specific Windows security feature to be active.
