[SOLVED]VAC Clone

Sorry, I am new to this whole system, but i need to ask, is there a sort of VAC clone that can be used on private offline servers? We host quite a few large lans and tend to have a quite a hacking problem... So basically what it must be able to do is check if the players are hacking and give the host/admin a full control feature where they can ban or unban as wanted...

don't exist that for the momment.....
u have to be online for kick or ban ppl...

learn coding and make your own system

ok, if i were to learn code and do it, which sounds AWESOME! not being sarcastic. What language do you recommend i learn please?
