If AI agents are the new operating system, then AI add-ons are the new applications; and a new type of AI firewall is required to maintain security.
AIR Security is emerging from stealth with $50 million funding and a firewall, also called AIR, built for AI agents. The funding is led by Sequoia Capital and Greenoaks together with a range of prominent individual industry angels.
This follows AIR Security’s research that found more than 17,800 public AI add-ons (representing 6.7M installations) relying on untrusted external instruction sources. The firm also discovered AI Skills in the wild impersonating companies like Anthropic and OpenAI and designed to bypass security reviews and execute arbitrary code.
