Aryon Security Raises $29 Million in Series A Funding to Bring Preventive Enforcement to Modern Cloud Security

TEL AVIV, Israel--(BUSINESS WIRE)--Aryon Security, a Cloud Security Enforcement Platform, today announced it has raised $29 million in Series A funding led by Brightmind Partners, with participation from Datadog Ventures, Shlomo Kramer’s new fund Skinos Ventures, and existing seed investors Blumberg Capital and Viola Ventures. The new financing brings the company’s total funding to $38 million, just over a year after exiting stealth, and is supported by prominent angel investors and serial entrepreneurs, including George Kurtz, CEO of CrowdStrike; Robert Herjavec; Yevgeny Dibrov, CEO of Armis; and Nadir Izrael, CTO of Armis.

Leading the round is Brightmind Partners, a firm co-founded by Stephen Ward, former CISO at The Home Depot and TIAA. Previously, he served as a Managing Director at Insight Partners, where he led cybersecurity investments. Datadog joins as a strategic investor, deepening its commitment to reducing security complexity across the full cloud risk lifecycle — from prevention to remediation.

“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,” said Ward. “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.”

"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," said Bharat Sajnani, Head of Datadog Ventures. "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.”

As AI accelerates infrastructure changes and cloud complexity, security teams are struggling to keep pace with the speed at which risks are introduced into cloud environments. By the time most cloud risks are detected, they are already live in production, forcing organizations into a constant cycle of remediation. Aryon’s platform enables organizations to enforce security policies before risks reach production, applying consistent controls across the entire cloud infrastructure. This preventive approach helps enterprises avoid up to 95% of traditional CSPM alerts while dramatically reducing risk and operational overhead.

“We built Aryon because cloud security needs to move from ‘know misconfigurations’ to ‘NO misconfigurations’,” said Ron Arbel, CEO and co-founder of Aryon Security. “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.”

Since emerging from stealth in 2025, the company has gained traction among mid-to-large enterprises operating complex cloud environments across highly regulated industries, including healthcare, banking, insurance, telecommunications, shipping, and the industrial sector.

Aryon’s platform is driving impact across three primary use cases. First, organizations undergoing cloud migration or M&A processes leverage Aryon’s preventive approach to ensure their environments are secure by design, allowing them to scale into the cloud without accumulating large volumes of misconfigurations that later require remediation. Second, enterprises with mature and complex cloud environments use Aryon to dramatically improve efficiency by preventing up to 95% of new security gaps from any source, from “ClickOps” to pipelines, allowing teams to shift their focus from constant firefighting to addressing existing issues. Finally, a growing number of organizations have come to realize that prevention is the only scalable approach to cloud security. Aryon enables them to operationalize this mindset, enforcing policies at scale in a way that is safe for production, granular, and natively integrated with exception management processes.

“The best companies don’t just improve a category, they redefine it,” said Robert Herjavec, entrepreneur, cybersecurity investor, and Shark Tank star. “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.”

Aryon was founded by a team of "Forbes 30 Under 30" honorees and veterans of "Matzov," the IDF’s elite cybersecurity unit. CEO Ron Arbel, CTO Ariel Litmanovich, and CPO Yair Ladizhensky built the company on insights gained while securing Project Nimbus, Israel’s $7.2 billion national cloud infrastructure contract. Having designed systems to protect the most sensitive environments in the world, the founders identified a fundamental gap between an organization’s cloud security desired posture and its real-world enforcement.

“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,” said Shlomo Kramer, a strategic advisor for Skinos Ventures.

Aryon’s long-term vision is to extend preventive enforcement beyond cloud infrastructure to the broader enterprise environment. As organizations adopt more AI systems, SaaS applications, and distributed technologies, the company believes the core challenge remains the same: policies are defined, but not consistently enforced. Aryon aims to help organizations consistently enforce security controls across environments before risks reach production.
