I am only guessing here. You need to ask Mr Kay if you want the real answers.
First, I am not sure if you are referring to BlockSafe or CSI, so here is an answer for each.
CryptoDefender is a different product than GuardedID. They are focused at two different markets (with some of the same functionality). I speculate they renamed it to ease confusion.
For ACS/CSI channel partner, well that is the same as Trustwave rebranding Duo. I guess channel partners like to make it look like their own products.
