Riot adds on-demand option for Vanguard anti-cheat in League of Legends and Valorant

Riot Games introduced an optional on-demand mode for its Vanguard anti-cheat software in League of Legends and Valorant. Players who meet hardware requirements and enable certain Windows security features can now run the kernel-level driver only while playing rather than at system startup.

The company developed the feature, called Vanguard Pre-Check, after collaborating with the Xbox OS Security Team at Microsoft on Windows kernel improvements. These changes address driver and memory exploits used by cheats such as wallhacks, aimbots, and triggerbots.

Requirements for on-demand mode To use the new mode, players must run at least Windows 11 25H2 with UEFI Mode, Secure Boot, and Trusted Platform Module 2.0 enabled. They also need Virtualization-Based Security, Hypervisor-Protected Code Integrity, and Input-Output Memory Management Unit support.

Riot stated that 35 percent of players already meet these requirements and can switch with their next update. The remaining 65 percent must adjust settings if they want the on-demand option. The company said the update is optional and that players who prefer the previous always-on configuration can continue using it without changes.
