Aryon

Aryon Security is an Israeli cloud security company based in Tel Aviv that develops a cloud security enforcement platform. Rather than detecting misconfigurations and vulnerabilities after they appear and then remediating them, the platform is designed to enforce security policies at deployment so that risks are prevented from reaching production. It scans assets for security misconfigurations and enforces organization-defined policies, and is described as technology-agnostic, covering infrastructure managed through infrastructure-as-code, manual console changes ("ClickOps"), or third-party providers.

The company frames its approach around the argument that organizations migrating to the cloud must manage tens of thousands of configurations, where a single misconfiguration can create an exploitable gap, and that AI-accelerated development and attack tooling leaves too little time for detect-and-fix workflows. Stated use cases include maintaining secure-by-design infrastructure during cloud migration, preventing security gaps regardless of their source, and operationalizing prevention as a scalable cloud security practice. Longer term, Aryon says it intends to extend the platform beyond cloud infrastructure to broader enterprise environments, including AI systems, distributed technologies and SaaS applications.

Founding story

Aryon was founded in late 2024 by Ron Arbel (CEO), Ariel Litmanovich (CTO) and Yair Ladizhensky (CPO; earlier described as VP R&D), all graduates of Matzov, the IDF's Encryption and Information Security unit, and all under 30 at the time of the seed round. The team worked on securing Project Nimbus, Israel's national cloud infrastructure contract, an experience they say exposed a gap between the security organizations expect and what is achieved in practice. Aryon is Arbel's second venture: he was previously COO of Cyberlium (also rendered Cyberilium), whose flagship product was acquired by CYE in August 2023, and he founded that company with two friends from his unit after being accepted to MIT for an MBA he did not pursue. Litmanovich is a recipient of the Israel Defense Award and was responsible for the IDF's transition to the cloud; Ladizhensky previously led R&D intelligence-gathering work at Paragon. Arbel and Ladizhensky also co-founded the Matzov Entrepreneurs Forum.

Business model

Aryon sells a cloud security enforcement platform to enterprises, deployed across their cloud environments to apply organization-defined policies at deployment time. The company reports paying enterprise customers and states it is expanding both its development group and its commercial operations following its Series A.

Aryon serves paying enterprise customers of its cloud security platform. Public sources do not specify pricing or contract structure.

Traction

Headcount grew from 18 employees at the March 2025 seed announcement to 44 at the June 2026 Series A, with continued hiring and plans to double the development team. The company reports paying customers including U.S. banks Valley Bank and OceanFirst Bank, IBI Investment House, International Seaways and New American Funding. Cumulative funding stands at $38 million. Arbel has said the Series A was an easy round to raise and, in a July 2026 interview, that he has raised close to $40 million for Aryon and roughly $40 million across his two ventures combined.

Latest developments

In June 2026 Aryon announced its Series A, reported at $25 million by Israeli outlets and at $29 million by SecurityWeek and Axios, led by Brightmind Partners with Shlomo Kramer's Skinos Ventures, Datadog Ventures, Startpoint Capital, existing investors Blumberg Capital and Viola Ventures, and individual investors including CrowdStrike CEO George Kurtz and Armis founders Yevgeny Dibrov and Nadir Izrael. Total funding reached $38 million. The company said it would use the capital to scale operations, double its development group, expand commercial activity and extend the platform beyond cloud environments. In a July 2026 interview, Arbel discussed the difficulty of the Series A stage and cautioned that cybersecurity and AI valuations had detached from revenue.
