BattlEye

BattlEye is a proprietary anti-cheat software designed to detect players that hack or abusively use exploits in an online game. It was initially released as a third-party anti-cheat for Battlefield Vietnam in 2004 and has since been officially implemented in numerous video games, primarily shooter games such as PUBG: Battlegrounds, Arma 3, Destiny 2, and DayZ.

BattlEye is developed by German company BattlEye Innovations e. K., headquartered in Reutlingen.

BattlEye supports Valve Corporation's Proton compatibility layer and is usable on the Steam Deck.

Technology
BattlEye continuously updates in background processes and has its own infrastructure which is connected to the game servers. It interacts with the game at the kernel level. BattlEye is said to support a "global" ban system for cheaters using unique fingerprints that stop players switching accounts to defeat bans.
