A six month old startup just raised fifty million dollars to build something new: a firewall for AI agents. AIR Security discovers which AI agents are quietly running inside a company, checks every plugin and skill those agents can use, and blocks anything that looks wrong before it acts. Sequoia led the first ten million. Greenoaks followed with forty more, the same day. Investors include the co-founder of Wiz, the cloud security company Google just bought. As companies plug AI agents into their databases and code, nobody's actually watching what those agents touch. That's the gap AIR is betting on. And judging by how fast this round closed, investors think that gap is closing fast too.
