Assaf Rappaport

Assaf Rappaport (Hebrew: אסף רפפורט; born 28 August 1983) is an Israeli entrepreneur and cybersecurity executive. He is a co-founder and chief executive officer of Wiz, a cloud security company, and a co-founder of the cybersecurity startup Adallom. Rappaport previously was the head of Microsoft’s Israel Research and Development (R&D) Center. He gained significant recognition following the announcement in March 2025 that Alphabet Inc., Google’s parent company, intended to acquire Wiz for approximately US$32 billion, which, if completed, would mark the largest acquisition of an Israeli technology company to date.[1][2]

Rappaport was born on 28 August 1983, in Israel.[3]

Career

Early roles

After his military service, Rappaport briefly worked as a consultant at McKinsey & Company before starting his own cybersecurity venture.[5][6]

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.[1][7]

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.[1] He also led the company’s Cloud Security Group, working to improve security offerings within Azure.[8]

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.[2] Wiz provides a platform for real-time security risk assessment across multiple cloud environments, including Amazon Web Services (AWS), Azure, and Google Cloud.[5] The company aimed to offer a cloud security platform capable of scanning across major cloud providers.

Wiz emerged from stealth mode in December 2020 with a US$100 million Series A funding round.[9] By mid-2021, Wiz had achieved “unicorn” status after raising several hundred million dollars in additional funding, placing its valuation at around $6 billion.[9] In February 2023, Wiz secured another $300 million in funding, bringing its valuation to $10 billion,[9]

Founding and early growth

Acquisition by Google

By 2023, Wiz served over 40% of Fortune 100 companies.[5][11] 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.[2] The deal, if finalized, would be the largest in Google’s history, as well as the largest acquisition of an Israeli technology company.[1][3] Wiz is expected to be integrated under Google Cloud while retaining its independence in serving multi-cloud customers.[2]
