Yoav Alon
About Yoav Alon
Yoav Alon is the CTO of Orca Security, a cloud security company. Crunchbase lists him in that role since July 2019. Orca describes him as a security veteran who appears on the Microsoft Security Response Center Most Valuable Researcher list (BlackHat 2019).
Before Orca he was a researcher and team leader in Unit 8200, a chief architect at Hyperwise Security, and a security architect at Check Point Software Technologies. Orca's bio says he enjoys hunting for Linux and Windows vulnerabilities. Conference bios say he holds a BSc in Computer Science from the Open University of Israel and has more than 12 years in security. He is based in Israel.
Public data on his angel activity is thin. Tracxn lists one investment, the Rein Security seed round of January 2026, and tags his activity as Israel-based and focused on enterprise applications and enterprise infrastructure. Dealroom and Crunchbase also list him among the Rein Security seed investors.
We found no public record of earlier angel investments, a fund, or an angel syndicate.
Rein Security raised an $8M seed round announced in late January 2026, led by Glilot Capital. Other participants were Ofer Ben-Noon and Amir Jerbi, alongside Alon. Calcalist describes the company as addressing vulnerabilities in application security and AI. It was founded in 2024 by Unit 8200 alumni Matan Bar-Efrat (CEO) and Netanel Rubin (CTO), with offices in Tel Aviv and New York. Coverage describes its product as runtime application security, including API security and vulnerability prioritization.
With a single reported deal, he has no stated thesis. His one known investment is a seed-stage, Israel-founded security company working on application security and AI. His own background is in cloud security, vulnerability research and security engineering, so security founders are the closest match to his experience. We found no public statement from him about check size, stage preferences or what he looks for in founders.
