The end points can be encrypted by every techonology imaginable, that only prevents people who shouldn't be able to access the data from accessing it.
The guy who leaked this stuff was granted access to it. He had the passwords to open everything he leaked, so the problem is not (a possible) lack of encryption but the fact that he was able to access so much without anyone noticing. He seemingly downloaded more files than one person could read in a year, how was this not noticed?
