Israeli startup Air Security has emerged from stealth with $50 million in funding led by Sequoia and Greenoaks. The company addresses security risks in AI agent extensions and third-party tools.
Air Security focuses on securing extensions and tools integrated into AI agents, which have become critical infrastructure for enterprise deployments. The company's research found that thousands of AI add-ons rely on untrusted sources, creating significant security vulnerabilities.
The funding round was led by Sequoia Capital and Greenoaks Capital, reflecting investor confidence in the emerging security category. As AI agents increasingly automate business processes and access sensitive systems, securing their plugin ecosystems has become a pressing need.
The startup's solution addresses gaps in current AI security frameworks by providing visibility and control over third-party extensions before they execute within AI environments. This approach prevents malicious or compromised tools from accessing sensitive data or performing unauthorized actions.
Air Security joins a growing cohort of security startups focused specifically on AI risks. The company plans to use the funding to expand its platform capabilities and scale operations.
