Early roles After his military service, Rappaport briefly worked as a consultant at
McKinsey & Company before starting his own cybersecurity venture.
Adallom (2012–2015) In 2012, Rappaport co-founded
Adallom, a
cloud access security broker (CASB), with Ami Luttwak and Roy Reznik. Adallom specialized in protecting data in software-as-a-service (SaaS) applications. Within three years, it was acquired by
Microsoft in July 2015 for approximately $320 million.
Microsoft (2015–2019) Following the acquisition, Rappaport and his co-founders moved to Microsoft. At the age of 34, he was appointed head of Microsoft’s Israel Research & Development Center, which employed around 1,500 people.
Wiz (2020–present) Founding and early growth In January 2020, Rappaport left Microsoft to co-found
Wiz with Ami Luttwak, Roy Reznik, and Yinon Costica. By mid-2021, Wiz had achieved “unicorn” status after raising several hundred million dollars in additional funding, placing its valuation at around $6 billion.
Acquisition by Google By 2023, Wiz served over 40% of Fortune 100 companies. In mid-2024, reports suggested that
Alphabet was interested in acquiring Wiz. Although Rappaport initially rejected an offer of about $23 billion to explore an
initial public offering (IPO), negotiations resumed amid a weakening IPO market. On 18 March 2025, Alphabet announced it had entered into an agreement to acquire Wiz for $32 billion in cash, subject to regulatory approvals. == Personal life ==
