There are a bunch of units under the Israeli intelligence corps, each doing their own thing. They are not the units with the 007 spies, they are technological units with a very small minority of them in defensive/offensive cybersecurity.

Looking at the profiles in that page it looks like all of them are just programmers/integrators or training other how to use the intelligence systems that are in 8200. not much spy shit.

If it's on linkedin, it's not really secret.
