Aryon Security, a cloud security enforcement platform, announced that it has raised $29 million in Series A funding led by Brightmind Partners, with participation from Datadog Ventures, Shlomo Kramer’s Skinos Ventures, and existing investors Blumberg Capital and Viola Ventures. The financing brings the company’s total funding to $38 million, slightly more than a year after emerging from stealth.
The round also received support from several prominent angel investors and cybersecurity leaders, including CrowdStrike CEO George Kurtz, entrepreneur Robert Herjavec, Armis CEO Yevgeny Dibrov, and Armis CTO Nadir Izrael.
Brightmind Partners, co-founded by former The Home Depot and TIAA CISO Stephen Ward, led the investment. Datadog joined as a strategic investor, strengthening collaboration around reducing complexity throughout the cloud security lifecycle.
Aryon was founded by CEO Ron Arbel, CTO Ariel Litmanovich, and CPO Yair Ladizhensky, veterans of the Israeli Defense Forces’ elite Matzov cybersecurity unit and Forbes 30 Under 30 honorees. The founders previously worked on Project Nimbus, Israel’s $7.2 billion national cloud infrastructure initiative, where they identified challenges associated with enforcing cloud security policies at scale.
As AI-driven infrastructure changes increase the speed and complexity of cloud environments, organizations are struggling to identify and remediate risks before they reach production. Aryon addresses this issue by enabling enterprises to enforce security policies before vulnerabilities become active. The company says its approach can prevent up to 95% of traditional cloud security posture management alerts while reducing operational burdens.
Since coming out of stealth in 2025, Aryon has gained customers among mid-to-large enterprises operating in highly regulated industries, including healthcare, banking, insurance, telecommunications, shipping, and industrial markets.
The company said customers are using its platform in several ways. Organizations involved in cloud migration projects and mergers and acquisitions use Aryon to establish secure environments from the outset. Enterprises with mature cloud infrastructures are leveraging the platform to reduce the number of new security gaps introduced through pipelines and manual configuration changes. Others are adopting preventive security models to enforce policies consistently and at scale while integrating with exception management processes.
Looking ahead, Aryon plans to expand its preventive enforcement capabilities beyond cloud infrastructure to encompass AI systems, SaaS applications, and other distributed enterprise technologies. The company believes organizations increasingly need mechanisms that ensure security policies are consistently enforced before risks reach production.
KEY QUOTES:
“Having served as CISO for some of the world’s largest enterprises, I’m seeing firsthand how AI is increasing cloud complexity while also enabling attackers to exploit gaps faster than ever before. In this post-Mythos world, the traditional ‘detect and remediate’ model is no longer enough. Instead of allowing security gaps to reach production only to be remediated weeks or months later, organizations need an enforcement layer that prevents risks from going live in the first place. After working closely with Ron, Ariel, and Yair over the past year, my conviction in Aryon’s vision has only strengthened.”
Stephen Ward, Co-Founder, Brightmind Partners
“AI and rapid infrastructure changes are introducing risk to cloud security in a way that we have never seen before – and faster than reactive remediation efforts can effectively manage. Aryon’s preventive approach complements how Datadog already helps customers detect and resolve risks in production so that they can ship with control and confidence. We’re proud to support the Aryon team and all the important work they are doing.”
Bharat Sajnani, Head Of Datadog Ventures
“We built Aryon because cloud security needs to move from ‘know misconfigurations’ to ‘NO misconfigurations’. Infrastructure is changing faster than security teams can manually keep up with, and enterprises can no longer afford to discover risks only after they are already in production. Aryon makes prevention operational, scalable, and safe for the world’s most complex cloud environments.”
Ron Arbel, CEO And Co-Founder, Aryon Security
“The best companies don’t just improve a category, they redefine it. Cloud security can no longer rely on finding issues after they happen. Aryon is redefining cloud security by moving enterprises from detecting risks after the fact to preventing them at the source.”
Robert Herjavec, Entrepreneur, Cybersecurity Investor, And Shark Tank Star
“As an early investor in Aryon, and now with this new investment, I strongly believe in this team and support their journey to transform cloud security, from know misconfigurations to no misconfigurations.”
Shlomo Kramer, Strategic Advisor, Skinos Ventures
