AIR Security

Context firewall for AI agent fleets: discovers agents, continuously vets the skills, plugins, and MCP servers they touch, and blocks what fails.

Proof of life. Emerged from stealth with $50M raised across two seed rounds led by Sequoia and Greenoaks, September 2026

AIR treats what an AI agent installs and talks to as a supply chain problem. Discovery finds agents running across a company's environment, including unapproved or personal-account use. A vetting layer continuously re-checks every skill, plugin, and MCP server an agent touches against a maintained whitelist, because an approved package can turn risky when its code changes or its developer account is compromised. An enforcement layer hooks into agents to intercept actions like loading a skill or fetching content, and the company also runs a marketplace of vetted add-ons, filtering out roughly 27 percent of the skills it evaluates online. Founded by two Unit 8200 veterans, it reports over 20 customers with demand concentrated in financial services and pharmaceuticals.
