This has never happened. We did not have anyone ever hack or exploit anything. We had a lot of attempts so far, but our rules are if the server is hosted with us (standard or premium license) we would refund all damages to the client. If a client has a basic license (which means he is hosting it on his server) it's not insured.
What we have learned in this business is that there are a lot of bad people who are not interested in gambling at all, they just search for casinos and try to break in, we try to detect that as soon as possible and prevent any attempts. It's normal with any software or online platform. There are always good people and bad people.
