BattlEye (BE) was founded by Bastian Suter in October 2004. Starting out as an external 3rd-party anti-cheat for Battlefield Vietnam, first versions were released pretty soon and it rapidly gained first acknowledgement. In early 2005, it was integrated in the first professional leagues. Due to request by the community, BattlEye was then ported to Battlefield 1942 and again used by some leagues.
Today Battleye is one of the most famous and acknowledged anti cheats world wide, being us in several games such as PUBG, Rainbow Six Siege, Fortnite and more.
