Are there any open source anticheats?

Hello, I was wondering if there are any open source anticheats that I could use in my game, as there seems to be already a few modules posted in community tutorials, but I do not know which one to choose (and if I should)

there’s a bunch of them… but they get patched quite easily and quickly since they are open source and open 2 the public…

The best thing to do is to script your game with security in mind. Anti-noclip should be tailored to your game, anti-fly is about ten lines long. It’s not too hard to take care of most vulnerabilities.
