Thick Client Pentesting
Thick client security assessment is basically testing desktop or rich applications like Windows or Java/.net apps to see if there are any security holes. It's not just about the server, we also look at how the app stores data on the computer, how it talks to the server, and whether someone could tamper with it or reverse-engineer.
