Vanguard: League of Legends Anti-Cheat

Updated: 13th January 2024 3 min read

In the dynamic world of online gaming, the battle against cheating has become increasingly challenging. Game developers continually strive to create an environment where fair play prevails, and one such notable effort is Riot Vanguard, an anti-cheat system developed by Riot Games. In this blog post, we will delve into the intricacies of Riot Vanguard, exploring its purpose, functioning, and the controversies surrounding its implementation.

What is Riot Vanguard?

Riot Vanguard is a robust anti-cheat system specifically designed for Valorant, a popular tactical first-person shooter developed by Riot Games. The primary goal of this system is to maintain the integrity of the gaming experience by preventing cheaters and hackers from gaining an unfair advantage. Rigorous testing, internal reviews, and external security audits by industry experts underscore Riot Games’ commitment to providing a secure gaming environment.

How it works

Riot Vanguard works at the kernel level of the operating system to provide a robust and proactive defense against cheats and hacks in games like Valorant. Here’s a simplified explanation of how Vanguard operates at the kernel level:

Kernel-Level Access:

The kernel is the core part of an operating system that manages system resources and serves as a bridge between software and hardware. By operating at the kernel level, Vanguard has deep access to system functions, allowing it to monitor and control system activities more closely.

Enhanced Security:

Working at the kernel level provides Vanguard with enhanced security measures. It can detect and prevent cheats more effectively by having a more comprehensive view of the system’s inner workings.

Proactive Defense:

Vanguard employs a proactive defense mechanism, aiming to identify and neutralize potential threats before they can impact the game. This real-time approach is designed to stay ahead of cheat developers and maintain the integrity of the gaming experience.

Continuous Monitoring:

Vanguard continuously monitors system activities while the game is running. This includes inspecting the interactions between the game client and the operating system, checking for any unauthorized modifications or attempts to exploit vulnerabilities.

Blocking Cheat Processes:

If Vanguard detects a cheat or hack attempting to interfere with the game, it can take immediate action to block the malicious processes. This prevents cheats from gaining an unfair advantage and helps ensure a level playing field for all users.

Vanguard and League of Legends

While Riot Vanguard is not currently in use for League of Legends, the decision to potentially introduce it is driven by the essential need for fair play. Challenges posed by scripters, bots, and security breaches have prompted Riot Games to explore the integration of Vanguard into League of Legends, aiming to bolster the game’s defenses and ensure the protection of the player experience.

Anticipating Vanguard Errors

As Riot Vanguard is not currently in use for League of Legends, potential errors and issues related to Vanguard are speculative at this point. However, if introduced, players may encounter errors that restrict access. A systematic approach involving the verification of system requirements, including updated Windows and configurations discouraging cheating, would be crucial. If issues persist, completing required Windows Updates, performing a full reboot, or undertaking a clean re-installation of League of Legends/Vanguard may resolve the problem.


While Riot Vanguard is not currently employed in League of Legends, the potential for its integration underscores Riot Games’ ongoing commitment to maintaining fair play and competitive integrity. As the industry evolves, the implementation of advanced security measures becomes essential. Balancing these measures with user privacy considerations is key to creating a secure and enjoyable gaming environment. As the exploration of Riot Vanguard’s integration into League of Legends unfolds, the gaming community can anticipate potential enhanced defenses against cheating, reinforcing the principles of fairness and integrity in online gaming.
