It sure can't hurt to rebrand. I also wonder if they chose the name Zerify so it also (in a way) correlates to Zscaler. When doing a Google search on Zscaler, it clearly comes up as: Zscaler: The Zero Trust Leader

I'm pretty sure that the API deal/those involved knew about the new name change well before us because SFOR has been working on the new name/branding for about a year.
