Riot Vanguard is a kernel-level anti-cheat developed by Riot Games. Vanguard initially released as the anti-cheat used for Valorant on April 7th, 2020. Originally designed for Windows only alongside Valorant, the console edition of Valorant released in June 2024 has an anti-cheat using the same branding, however this anti-cheat functions very differently. Vanguard has received much criticism because of its intrusive nature. Vanguard was introduced into League of Legends on April 11th, 2024.
