Assaf Rappaport is an Israeli entrepreneur and cybersecurity executive best known as the cofounder and chief executive officer of Wiz. Before Wiz, he co-founded Adallom, a startup focused on protecting data in software-as-a-service applications. After Microsoft bought Adallom in 2015, he moved into a bigger role there and later became head of Microsoft's Israel research and development center while also leading the Cloud Security Group.
In 2020, Rappaport left Microsoft and started Wiz with Ami Luttwak, Roy Reznik, and Yinon Costica. Wiz built cloud security software that scans major storage providers including Amazon Web Services and Microsoft Azure to spot and rank security risks. The company passed $100 million in revenue in 2023, then pushed for faster hiring and fundraising. In March 2026, Alphabet bought Wiz for $32 billion in cash, a deal that powered his fortune.
How Assaf Rappaport makes money
Rappaport's wealth comes from cybersecurity. He first made his name by co-founding Adallom in 2012, then joining Microsoft after that company was acquired in 2015. At Microsoft, he worked on cloud security and led the Israel research and development center. Those roles helped set up his next company, Wiz, where he became chief executive officer and helped build a product for large businesses running across multiple cloud systems.
The biggest driver of his fortune is Wiz. Forbes says he co-founded the Israeli cloud security business and owned a 10% stake in the company. Wiz software scans storage providers such as Amazon Web Services and Microsoft Azure to flag and prioritize security risks. Its customers include Fox, Morgan Stanley, and LVMH. In 2023, revenue topped $100 million. In March 2026, Alphabet acquired Wiz for $32 billion in cash.
Forbes net worth and what changed
Forbes estimated Rappaport's net worth at $1 billion on the World's Billionaires List in 2024. By 2025, Forbes put him at $2.2 billion. The rise came as Wiz kept growing as a cloud security company, added major customers, and built more scale around software that helps companies find and rank risks across cloud storage and infrastructure used by large enterprises.
As of October 20, 2026, Forbes' real-time billionaires tracker estimated his net worth at $2.3 billion. The key event behind that latest figure was Alphabet's March 2026 purchase of Wiz for $32 billion in cash. Forbes also notes that Rappaport held a 10% stake in Wiz. That ownership position tied his wealth closely to the value created when the company grew quickly and then sold.
