Cybersecurity startup Aryon Security today announced raising $29 million in Series A funding. To date, the company has received $38 million in funding.
The fresh investment round was led by Brightmind Partners, with additional support from Datadog Ventures, Skinos Ventures, and previous backers Blumberg Capital and Viola Ventures.
Founded by Israel Defense Forces (IDF) cybersecurity veterans, Tel Aviv-based Aryon emerged from stealth in March 2025 to help organizations enforce security controls across their environments.
A technology-agnostic product, the solution provides proactive protections, scanning assets for security misconfigurations and enforcing organization-defined policies where necessary.
In the post Mythos-era, where AI accelerates software development and infrastructure changes, Aryon aims to prevent risks from reaching production by constantly applying controls across the organization’s cloud environments.
According to the startup, customers are using its platform to ensure secure-by-design infrastructure during cloud migration, to prevent security gaps from every source, and to operationalize prevention as a scalable approach to cloud security.
Long-term, Aryon aims to extend its platform beyond cloud, to broader enterprise environments, as organizations adopt more AI systems, distributed technologies, and SaaS applications.
“We built Aryon because cloud security needs to move from ‘know misconfigurations’ to ‘NO misconfigurations’,” said Aryon Security CEO and co-founder Ron Arbel.
“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,” Arbel added.
