Easy Anti-Cheat, the cheat-prevention system Epic has owned since 2018, uses machine learning to spot players who are cheating — analyzing patterns in how people play rather than just scanning for known cheat software. It runs in the background for Fortnite and hundreds of other games that license the technology from Epic.

Epic officially confirmed the use of machine learning in a February 2025 anti-cheat update, stating the system uses "statistical analysis and machine learning algorithms to identify suspicious activity." Easy Anti-Cheat operates at the kernel level of the operating system, monitoring memory usage, background processes, file integrity, and network traffic. Cheat detection combines signature scanning — matching known cheats from a database — with cloud-based machine learning analysis that flags behavioral anomalies. The system was originally developed by Finnish company Kamu, acquired by Epic in October 2018, and made available free to all developers via Epic Online Services in September 2021. In early 2025, Epic updated its ban policy from lifetime bans to one-year bans for first-time offenders. Privacy advocates have raised concerns about the kernel-level access the system requires.
