Hello good, I am looking for a private AntiCheat for my rust server, I need it to be only on the server side, so that the client does not need to execute anything in the background. I need it to detect all hacks, aimbot, no recoil, spider, esp ... I am willing to pay for it

Same as anticheat from everything, there are no magic pill that cures all diseases. We are kind of WEAK in way of blocking cheating software WITHOUT access to client. You can in theory catch aimbot and recoil scripts, but there will be always false-positive results
