Founding Story

Assaf Rappaport, Yinon Costica, Roy Reznik, and Ami Luttwak co-founded Adallom, a cloud access security company, which Microsoft acquired in 2015. The four then worked at Microsoft, where Rappaport led the company's Israel R&D center. They left in 2020 and founded Wiz in January of that year, betting that companies moving to public clouds needed a way to see their security risk without deploying agents on every server. Wiz came out of stealth in December 2020 with a $100 million Series A from Index Ventures, Sequoia Capital, Insight Partners, and Cyberstarts.
