You don't need to do this in real time, instead you could log the data (e.g. mouse clicks, key presses) to something like a database, Kafka, or Kenesis. Now you've unloaded the anti cheat logic to other servers.

You don't necessarily need to ban a player immediately. If you can accurately ban people within a day of using a cheat, then that's a pretty serious deterrent from using them.
