AIR came out of stealth with $50 million raised across two seed rounds. The security startup vets the skills, plug-ins and connectors that AI agents install. Its platform finds agents running inside a company, including unapproved tools and personal accounts. It intercepts agent actions and checks requested add-ons against a whitelist AIR maintains. AIR also runs a marketplace of add-ons it has already vetted. Sequoia led the first round and Greenoaks led the second. Founders Yair Saban and Niv Hoffman previously served in Israel's Unit 8200. Demand has been strongest in banking and pharmaceuticals, the company says. Rivals include Noma Security, Zenity, Astrix Security and Operant AI. New money will fund researchers and sales expansion in the US and Europe.
What changed
Agent skills, plug-ins and MCP servers carried no signing or vetting layer, unlike device drivers.
What it unlocks
Finding agents running inside a company and blocking skills that fail security checks.
