I actually hired, and we later fired, a couple of 'engineers' from Unit 8200. They were technically quite weak, and when Oct. 7 happened, I wasn't surprised at all. If this was the cream of the crop, the defense community should seriously re-evaluate the efficacy of the IDF.
In other words: virtually every Israeli has been in the military, and for the technically competent ones, were likely to be recruited into their offensive intelligence unit. Coupled with a government whose industrial strategy has been to promote business development in this sector, we are in a situation where practically every single founder of an Israeli tech company has a military service background.
Those with (offensive) infosec mindset end up founding infosec focused businesses, knowing that there is readily available investment available for them. As a result, the Venn diagram between the unit members and infosec business founders is likely to show a pretty big overlap.
