What Are Vanguard Security Requirements?
To help protect players and maintain competitive integrity, Riot Vanguard may require certain Windows security features to be enabled before launching Riot games or using Vanguard Pre-Check.
Depending on your system configuration, Vanguard may prompt you to enable one or more security features before launching a game.
If you're unsure which requirement needs attention, check the Vanguard system tray icon (VGTray) for more information and links to the relevant troubleshooting steps.
