Aryon Security (aryon.security), an Israel-based provider of preventive cloud security enforcement, has raised $29 million in Series A funding led by Brightmind Partners. The platform enables organizations to define and automatically enforce AI-powered policies that prevent risky configurations from reaching production across IaC, ClickOps, CLI, or third-party tools. The capital will support expansion in complex multi-cloud environments.
Cloud Security Funding Continues in 2026
The timing aligns with sustained investor interest in proactive cloud security. Native raised $42M in March 2026, targeting similar cloud risks. Aryon's approach focuses on deployment-time enforcement rather than post-deployment detection, addressing gaps in environments where misconfigurations persist.
Misconfigurations Persist Across Clouds
Research shows 45% of AWS, 63% of GCP, and 70% of Azure resources remain misconfigured. Up to 85% of organizations have plaintext secrets in code repositories. Traditional CSPM tools detect issues after deployment, leaving exposure windows that Aryon aims to close by enforcing policies at creation time.
Enforcement at Deployment Time
Aryon’s platform scans assets and applies granular policies without runtime agents or auto-remediation. It integrates with any existing workflow and claims to prevent up to 95% of CSPM alerts. This differs from competitors like Orca Security, which emphasize agentless scanning and runtime protection.
As CEO Ron Arbel stated:
“We built Aryon because cloud security needs to move from ‘know misconfigurations’ to ‘NO misconfigurations.’”
Brightmind Leads with Cybersecurity Focus
Brightmind Partners, a new firm focused exclusively on cybersecurity, led the round alongside Datadog Ventures, Blumberg Capital, and Viola Ventures. Total funding now stands at $38 million. The firm's operator backgrounds in companies like Armis and Tanium signal targeted support for Aryon's go-to-market in enterprise cloud security.
Market Growth Supports Proactive Shift
The cloud security market is projected to grow from $39.09 billion in 2025 to $97.93 billion by 2033 at a 12.2% CAGR. Rising AI-driven infrastructure complexity and regulatory demands are pushing capital toward preventive solutions over reactive detection. Aryon's agnostic design across multi-cloud setups positions it amid this expansion.
Strong Early Traction Signals Momentum
Aryon emerged from stealth in 2025 and was named among Startup Nation Central’s top 10 cybersecurity startups. The company has grown from four founders to 38 employees while securing backing from angels including George Kurtz of CrowdStrike.
