R oy Reznik is a serial entrepreneur and cybersecurity expert who co-founded the cloud security unicorn Wiz. He established the company in 2020 alongside Assaf Rappaport, Yinon Costica, and Ami Luttwak, the same team he worked with to build Adallom, which was sold to Microsoft. Reznik played a pivotal role in developing Wiz's agentless scanning technology, which revolutionized how organizations secure their cloud environments by providing instant visibility into risks. His technical leadership helped Wiz reach $100 million in annual recurring revenue in record time, attracting top-tier customers like Morgan Stanley and Fox.

In a landmark deal in March 2025, Google's parent company Alphabet acquired Wiz for $32 billion in cash, marking one of the largest cybersecurity acquisitions in history. Reznik held a 10% stake in the company, cementing his status as a billionaire. Before his success with Wiz, he served as a software team lead in the Israeli Intelligence Corps (Unit 8200) and held senior R&D roles at Microsoft following the Adallom acquisition. He continues to be a prominent figure in the global tech ecosystem.
