GCSOverwatch 2 Anti-Cheat
Blizzard’s own anti-cheat under the Defense Matrix banner: no declared kernel driver, phone-number checks on new accounts and over 1 million cheating bans since launch.
In plain EnglishThis page explains the anti-cheat that protects Overwatch 2 - the system that tries to catch and ban cheaters. It covers how strict that system is and how cheats try to stay hidden from it. No cheat is ever 100% safe, so always check a product's status before you buy. Overwatch 2 uses Defense Matrix, and its maker has not said whether it runs at kernel level. Caught cheaters get an account ban, and our database rates its detection strength low. The guide below covers how it detects, what a ban really costs and what kind of build survives.What anti-cheat does Overwatch 2 use?
Overwatch 2 is Blizzard’s free-to-play team shooter. Blizzard now sells it simply as Overwatch, and that is how its Steam page lists it. On PC it needs a Battle.net account. Blizzard does not name an anti-cheat product: its anti-cheat work sits under an initiative it calls Defense Matrix, which also tackles disruptive behaviour.
The game’s Steam page carries no anti-cheat notice at all, so no kernel-level anti-cheat is declared there. Blizzard is open about results, though. It says more than 1 million accounts have been banned for cheating since Overwatch 2 launched. Blizzard keeps the details private and has said it does not like to reveal what it is doing to catch cheaters. Its licence does say what the game may do: while it runs, it may monitor your computer’s memory for unauthorised third-party programs, and send Blizzard your account name and details of what it found. People do the rest. A Blizzard task force runs cheat investigations and reverse-engineers cheats to see how they work, and works with outside security vendors. SMS Protect adds a phone check: one number cannot sit on several accounts at the same time, which Blizzard says makes it harder for banned players to come back. Players with a connected Battle.net account, including everyone who had played since 9 June 2021, were let off. Blizzard says players caught using aimbots, spinbots or wall hacks can expect their accounts to be permanently banned. Its licence puts penalties on your Battle.net account, up to ending your licence to the game. It also says you cannot share your account and are responsible for every use of it, so the owner answers for a ban, whoever was playing. Bans reach the people around a cheater too. Blizzard has suspended or banned more than 40,000 accounts for deliberately grouping with cheaters. It has not said that it bans hardware, but SMS Protect means a new account needs a phone number that is not already on another account. We rate Overwatch 2 "Low" on client detection. Blizzard has not declared a kernel driver, and its licence describes the game watching memory for unauthorised programs. Enforcement is steadier than that rating suggests: Blizzard says it is turning its attention to catching cheaters faster. Players feed the system. You can report someone from the scoreboard in a few clicks. On console Blizzard now detects unapproved peripherals that add mouse and keyboard: in Season 18 it rolled out new tech to spot them faster, and said that using one in the Controller Pool means a full game account ban, whatever your rank or mode. Blizzard names aimbots, spinbots and wall hacks as the cheats that earn a permanent ban. So the build that lasts is the one that looks human: modest aim help and information you act on quietly, not a crosshair that snaps from target to target. Think about who you queue with, since Blizzard bans players for grouping with cheaters. And treat each account as hard to replace: at launch, a new account had to win 50 Quick Play matches before Competitive unlocked, on top of the phone check. The Overwatch 2 builds we keep current are below. One Overwatch 2 build is on sale right now, listed by how each one runs according to its own description.
