agree with enrux (again ) NoCheatPlus is the way to go since NoCheat is great but inactive now so NoCheatPlus is here to replace it . I also recommend using orebfuscator, since its the best anti-xray plugin which gets the job done (however the plugin uses a lot of ram and cpu)
I recommednd you using NoAntiCheatPlus, it is the continuation of NoCheat and has new features just a demonstration
