Israeli startup Aryon Security, which introduced its novel cloud security platform last year, has closed a $25 million Series A round. This brings the total capital raised since the firm's launch in late 2024 to $38 million.

The financing was spearheaded by US based Brightmind alongside Shlomo Kramer's Skinos Ventures. Additional backers include software firm Datadog, CrowdStrike chief executive George Kurtz, Startpoint Capital led by Sharin Fisher Dibrov, Armis founder Yevgeny Dibrov, Blumberg Capital and Viola Ventures. The latter two increased their prior commitments and were joined by new participants from varied sectors, among them actor and comedian Assi Cohen. Earlier investors featured Yasmin Lukatz, Rubi Aronshvili, Ofer Ben Nun, Idan Nurick, Asaf Touchmair, Ehud Barak and singer Omer Adam.

The venture was established by three alumni of the Israel Defense Forces elite cybersecurity unit known as the Center for Encryption and Information Security (Matzov). All three appeared on Forbes Israel's list of the 30 most prominent under 30. Chief executive Ron Arbel, chief technology officer Ariel Limanovich and chief product officer Yair Ladizhensky built the company on lessons learned while protecting the Nimbus national cloud infrastructure initiative valued at $7.2 billion.

The fast growing early stage firm already serves paying clients across insurance, finance, healthcare and shipping. Notable customers comprise IBI Investment Company, US banks Valley Bank and OceanFirst Bank, shipping operator International Seaways and mortgage provider New American Funding, a major player in American housing finance.

Enterprises now face a far more intricate cloud security landscape, intensified by advanced AI systems such as Claude Mythos that accelerate attack speeds. The conventional detect and remediate model has become inadequate, making proactive prevention the sole viable defense against potential security exposures before they arise.

Aryon champions this shift from reactive measures to preventive strategies. Its platform delivers particular value during cloud migrations and merger activities by helping intricate environments avert up to 90 percent of fresh security exposures. Security teams can therefore transition from constant firefighting to a scalable, forward looking posture.

The company currently employs 44 people and continues to recruit top talent for sales, engineering and research roles.

Shlomo Kramer, strategic advisor at Skinos Ventures, stated that as an early and continuing investor he has full confidence in the team and its mission to move cloud security from gap detection to gap prevention.

Arbel noted that the founders created Aryon to replace endless bug fixing with genuine prevention, shifting from cataloging every misconfiguration to eliminating them entirely. In an era of rapid AI driven infrastructure changes, organizations cannot rely solely on post breach discovery, and Aryon renders prevention feasible even within the most complex cloud setups.
