Ehud Barak, Asi Cohen and Omer Adam Back Cyber Startup That Raised Tens of Millions

The Israeli cyber startup Aryon Security, founded about a year and a half ago, has raised $25 million in a Series A round, with former prime minister and IDF chief of staff Ehud Barak, actor Asi Cohen and singer Omer Adam among the investors. The round was led by the U.S.-based cyber-focused Brightmind and Skinos Ventures, the new investment fund of cyber entrepreneur Shlomo Kramer, one of the founders of Check Point.

Also participating in the round were public software company Datadog, the Viola and Blumberg funds, CrowdStrike CEO George Kurtz, Armis founders Evgeny Dibrov and Nadir Izrael, and real estate executive Asi Tuchmaier. The company has now raised a total of $38 million since its founding at the end of 2024.

What does Aryon actually do? The company develops a security system for cloud environments, meaning the remote servers where organizations store their data. The problem it is trying to solve is not new: when an organization moves to the cloud, it has tens of thousands of system settings, and even a small mistake in one setting can create a security breach that attackers may exploit, sometimes within minutes. So far, traditional defense systems identified the breach only after it had already occurred, and then tried to fix it. Aryon says its platform works differently, preventing the breach from being created in the first place.

The three founders, Ron Arbel, Ariel Litmanovich and Yair Ledizjensky, are graduates of Matzov, one of the IDF's cyber units. The three previously worked on protecting Project Nimbus, Israel's national cloud infrastructure, and say that there they understood the gap between what organizations want to be secure and what is actually secure.

The company already has paying customers, including American banks, an international shipping company and an American mortgage company. It employs 44 people and is hiring more. "Organizations can no longer afford to discover risks only after they have already penetrated the organization," Ron Arbel said. "Aryon makes prevention practical, even in the world's most complex cloud environments."
