Illegal scoring has caused serious problems for live services.
I strongly suggest to prepare and release security for the client (app) from the point of time before the problem actually occurs.
Applying LIAPP allowed strong defense against alternative routing of the clients, hacking tools, and memory modulation in real time and the exposure of UNITY as well as game source codes.
For services that are around four years old, when comparing before and after LIAPP is applied, the difference in response is very prominent as feedbacks from the CS or community became very positive.
Based on my experience, LIAPP will be a great partner for the best live service.
