Aryon Security has raised $29 mn in Series A funding to expand its Cloud Security Enforcement Platform. Brightmind Partners led the round, with participation from Datadog Ventures, Skinos Ventures, Blumberg Capital, and Viola Ventures.
The financing brings Aryon’s total funding to $38 mn, just over one year after the company came out of stealth. Angel investors in the company include George Kurtz, CEO of CrowdStrike, Robert Herjavec, Yevgeny Dibrov, CEO of Armis, and Nadir Izrael, CTO of Armis.
Brightmind Partners was co-founded by Stephen Ward, former CISO at The Home Depot and TIAA. Ward also previously served as managing director at Insight Partners, where he led cybersecurity investments.
Datadog joined the round as a strategic investor. Its participation connects Aryon’s preventive cloud security approach with Datadog’s work across cloud risk detection, remediation, and production monitoring.
Ward said AI is increasing cloud complexity while attackers exploit security gaps faster. He said the traditional model of detecting and remediating cloud risks after deployment no longer gives enterprises enough control.
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.

Bharat Sajnani, head of Datadog Ventures, said AI and rapid infrastructure changes are creating cloud security risks at unusual speed. He said Aryon’s preventive approach complements Datadog’s ability to help customers detect and resolve risks in production.
As companies adopt AI and update infrastructure faster, security teams struggle to match the pace of cloud change. Many cloud risks are discovered only after they reach production, forcing teams into a constant remediation cycle.
Aryon’s platform enforces security policies before risks go live. The system applies consistent controls across cloud infrastructure and helps enterprises prevent misconfigurations before they become production issues.
The company says its preventive approach helps organisations avoid up to 95% of traditional Cloud Security Posture Management alerts. That reduces risk and lowers operational workload for security teams that already manage complex cloud estates.
“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.”
Since leaving stealth in 2025, Aryon has gained traction among mid-sized and large enterprises with complex cloud environments. Its customers operate in regulated sectors including healthcare, banking, insurance, telecommunications, shipping, and industrial markets.
Aryon’s platform supports three main use cases. Companies moving to the cloud or going through M&A use Aryon to make cloud environments secure by design before they scale.
Enterprises with mature cloud environments use Aryon to prevent new security gaps from sources such as manual ClickOps changes and deployment pipelines. That lets security teams reduce firefighting and focus more attention on existing risk.
A third group uses Aryon to operationalise prevention as the main cloud security model. The platform enforces policies at scale through granular controls, production-safe workflows, and exception management processes.
Robert Herjavec, cybersecurity investor and Shark Tank star, said cloud security cannot depend only on finding issues after they occur. He said Aryon is moving enterprises from after-the-fact detection toward prevention at the source.
Aryon was founded by Ron Arbel, CTO Ariel Litmanovich, and CPO Yair Ladizhensky. The founders are Forbes 30 Under 30 honorees and veterans of Matzov, the Israel Defense Forces’ elite cybersecurity unit.
The founding team built Aryon using experience from securing Project Nimbus, Israel’s $7.2 bn national cloud infrastructure contract. That work exposed the gap between a company’s desired cloud security posture and what it can enforce in real environments.
“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, strategic adviser for Skinos Ventures.
Aryon’s long-term plan is to extend preventive enforcement beyond cloud infrastructure. The company sees the same control problem emerging across AI systems, SaaS applications, and distributed enterprise technologies.
The company argues that enterprises often define security policies but fail to enforce them consistently. Aryon wants to help organisations apply controls before risks reach production across more parts of the enterprise environment.
According to Beinsure analysts, Aryon targets a growing weakness in cloud security architecture. AI accelerates infrastructure change, while reactive remediation leaves security teams chasing issues after deployment.
The value of preventive enforcement sits in reducing alert volume, blocking misconfigurations earlier, and giving regulated enterprises a safer route to cloud and AI adoption.
