Aryon Security raises $9 million Seed round to stop cloud breaches before they happen

With experience from Israel’s national cloud security efforts, founders seek to transform enterprise cloud protection.

Cybersecurity startup Aryon Security has emerged from stealth with a $9 million Seed round to develop a platform aimed at reshaping cloud security. Aryon’s Cloud Security Enforcement Platform seeks to move security from a reactive to a preventive approach, an ambition that could have broad implications for cloud-dependent enterprises.
The company’s leadership comprises CEO Ron Arbel, CTO Ariel Litmanovich, and VP of R&D Yair Ladizhensky—cybersecurity veterans who served together in Matzov, the elite IDF unit responsible for securing Israel’s national cloud infrastructure. Their experience working on Project Nimbus, a collaboration between the Israeli government and major cloud providers, directly informed Aryon’s technology.

The funding, led by Viola Ventures and Blumberg Capital, includes backing from high-profile industry figures such as serial entrepreneur Shlomo Kramer of Check Point, Imperva and Cato Networks, Maty Siman, founder of Checkmarx and Rubi Aronashvili, founder of CYE.
Traditional cloud security solutions primarily detect and address vulnerabilities only after systems are already running—an approach that often leaves organizations exposed to threats for extended periods. Aryon’s platform aims to eliminate that lag by proactively preventing misconfigurations and security gaps before they ever reach live environments. This shift is critical, given that misconfigurations account for 99% of cloud security breaches, according to a Gartner report.
“Today’s cloud security solutions are mainly reactive, only identifying problems after they appear,” said Shlomo Kramer. “Aryon changes that with a radically new approach that prevents risks before they happen, enabling even the most conservative organizations to adopt cloud technologies securely.”
The platform allows security teams to define and enforce policies in advance, automating risk mitigation rather than relying on engineers to resolve issues manually. By integrating seamlessly with an organization’s existing infrastructure—whether it relies on Infrastructure as Code (IaC) or manual configurations—Aryon seeks to eliminate inefficiencies that currently slow security operations.
Aryon’s leadership brings a mix of entrepreneurial and technical expertise. Arbel, previously COO of Cyberilium, helped lead the company’s sale to CYE in 2023. Litmanovich, a recipient of the Israel Defense Award, played a key role in transitioning the IDF to the cloud. Ladizhensky, formerly of Paragon, developed intelligence-gathering technologies that significantly boosted the company’s revenue.
The founders also co-established the Matzov Entrepreneurs Forum, a prominent startup network within Israel’s cybersecurity ecosystem.
