Aryon Security raises $25 million Series A backed by Shlomo Kramer, George Kurtz and Datadog Ventures
The Israeli startup argues traditional “detect and fix” cybersecurity is no longer sufficient.
Israeli startup Aryon Security has raised $25 million in a Series A round, bringing its total funding since its inception in late 2024 to $38 million. The round was led by U.S.-based Brightmind Partners and Shlomo Kramer’s Skinos Ventures, and included participation from Datadog Ventures, CrowdStrike CEO George Kurtz, Sharin Fisher Dibrov’s Startpoint Capital, and Armis founders Yevgeny Dibrov and Nadir Izrael.
Existing investors Blumberg Capital and Viola Ventures, which led the Seed round, also participated and increased their investment. Additional investors in this round include Israeli actor and comedian Assi Cohen. Other prominent backers from previous rounds include Yasmin Lukatz, Rubi Aronashvili (founder of CYE), Ofer Ben-Noon (Talon), Idan Nurik (Paragon), Ehud Barak, and singer Omer Adam.
Aryon argues that organizations today face a far more complex cloud security environment, particularly with the rise of advanced AI tools that accelerate the pace of attacks. In this environment, traditional “detect and then fix” models are no longer sufficient, and prevention, eliminating vulnerabilities before they emerge, is becoming the only viable security approach.
Aryon CEO Ron Arbel told Calcalist: “In the AI era, we are doing something fundamentally different. We say that with AI, there is no time to defend, we must reduce the attack surface. I have competitors, but I believe large companies will eventually move in our direction. Everyone is entering our space. It was a very easy fundraising round. Today there is no time to respond to attacks; you have to prevent them. If there is a breach, there is no time to fix it, each attack unfolds in minutes.
“We are one of the companies that will benefit from the new AI era. There are many areas where people question whether cybersecurity companies are even needed. I am building a large team, doubling our development group, and expanding commercial activity.”
Aryon was founded by veterans of "Matzov," the IDF’s elite cybersecurity unit. CEO Ron Arbel, CTO Ariel Litmanovich, and CPO Yair Ladizhensky built the company on insights gained while securing Project Nimbus, Israel’s $7.2 billion national cloud infrastructure contract. Aryon currently employs 44 people.
Its customers include IBI Investment House, U.S. banks Valley Bank and OceanFirst Bank, international shipping company International Seaways, and mortgage provider New American Funding, one of the leaders in U.S. housing finance.
