“The connection to Omer Adam brought us many clients”: Aryon raises $25 million in cyber funding

Israeli startup Aryon Security has raised $25 million in a Series A round, bringing the company’s total funding since its founding in late 2024 to $38 million.

The round was led by the US-based Brightmind fund and Skinos Ventures, Shlomo Kramer’s fund. Participants also included software company Datadog, CrowdStrike CEO George Kurtz, Startpoint Capital of Sharine Fisher Dibrov, and Armis founders Evgeny Dibrov and Nadav Zafrir. Blumberg Capital and Viola Ventures, which led the seed round, increased their investment and also took part in the current round, while additional investors joined this time, including actor and comedian Asi Cohen. Other prominent investors in previous rounds include Yasmin Lukatz, Robi Arnonshvili, founder of CYE, Ofer Ben-Noon of Talon Security, Idan Nuryk, founder of Paragon, Ehud Barak, and singer Omer Adam.

Company CEO Ron Arbel told Calcalist that “the connection to Omer Adam brought us many clients. We have long-term clients through Omer’s connections, he is one of our most active investors and we were his first investment in cyber.” Arbel added that “in the AI era we are doing something completely different. There is no time today to defend against cyberattacks, what is required is to reduce the attack surface. If there is a breach, there is no time to fix it when every attack takes five minutes. We are among the companies that will profit from the new AI era. There are many areas where there is a question of whether they are needed. Mythos, for example, makes many cyber companies redundant. I am building a very large team, we will double our development team and expand our deals.”

Aryon was founded by three alumni of Matzov, the Center for Encryption, Cyber and National Security, CEO Ron Arbel, CTO Ariel Litmanovitz, and CPO Yair Ladzjenski, who founded the company based on insights gained while securing Project Nimbus, Israel’s $7.2 billion national cloud infrastructure project. The company currently employs 44 people, and its customers include IBI Investment House, American banks such as Valley Bank and OceanFirst Bank, the international shipping company International Seaways, and the US mortgage company New American Funding.

Organizations today face a new and far more complex reality in cloud security, especially with the emergence of advanced AI tools like Claude Mythos, which make the pace of attacks significantly faster than before. This means the traditional security model of “detect and then fix” is no longer sufficient, and the only effective way to protect the cloud is through prevention, meaning not allowing theoretical security gaps to emerge in the first place.
