Founders and military intelligence
Ctech reported that Assaf Rappaport, Ami Luttwak, Roy Reznik and Yinon Costica "served in the Intelligence Corps, in Units 8200 and 81" (Intelligence Corps; Unit 8200), and that after leaving the army they "reunited in 2012 to found their first startup", Adallom.[2] Microsoft named the co-founders as Rappaport, Luttwak and Reznik.[1]
Ownership
Ctech reported that Adallom was sold to Microsoft in 2015 for $320 million, after which the founding team "took over the reins of Microsoft's R&D center in Israel", with Rappaport as general manager. They left in 2020 to found Wiz.[2] Microsoft said Adallom's technology would complement its Office 365 and Enterprise Mobility Suite security offerings.[1]
