Looking for decent antihack

Hi

Our server recently got breached by some hackers and somehow they could bypass the antihack (pinkof) which is server sided too and also added crc32 check. So I'm looking for a decent antihack for season 8 and I'm willing to pay. If anyone has a suggestion or interested please pm me.
I've tried MUGuard, UGK and some other antihack but they don't seem to reply to my emails. I have also tried searching through RZ but yeah same thing they are inactive, also tried open sources but they dont work for season 8 or they just dont work at all.

Thanks
