Enterprises aren’t just adopting AI agents. They’re inheriting an entirely new supply chain of skills, plugins, and tools that can change at any moment.”
— Yair Saban, co-founder and CEO of AIR
The recognition follows AIR’s emergence from stealth in September with $50 million raised across two seed rounds with a $10 million round led by Sequoia and a $40 million round led by Greenoaks.

AIR provides a comprehensive security layer for enterprise AI agents, continuously assessing the risk of every agent and the entire ecosystem of AI add-ons that extend its capabilities, including skills, plugins, MCP servers, and more. By combining continuous vetting, real-time security enforcement, and a trusted marketplace of pre-vetted AI add-ons, AIR enables enterprises to securely adopt, govern, and scale AI agents without limiting their potential.
This approach enables security teams to:
• Assess agent and add-on risk: Evaluate every AI agent, its permissions, connected capabilities, and potential security exposure.
• Continuously vet the AI supply chain: Detect risks, changes, and malicious behavior across skills, plugins, MCP servers, and other AI add-ons.
• Enforce security at runtime: Apply policies and prevent unsafe interactions, tool executions, and unauthorized agent actions.
• Enable trusted capabilities: Provide employees and agents with a safe marketplace of pre-vetted, approved internal and external AI add-ons.
“Enterprises aren’t just adopting AI agents. They’re inheriting an entirely new supply chain of skills, plugins, and tools that can change at any moment,” said Yair Saban, co-founder and CEO of AIR. “Approving an AI add-on once isn’t enough. Organizations need to know what their agents are using, whether those components remain trustworthy, and when to revoke access. The recognition by the Fortune Cyber 60 reinforces the importance of the problem we’re solving.”
