AIR Security's platform finds the AI agents running inside a company. It continuously vets the skills, plugins, MCP servers and other add-ons those agents load, then blocks unsafe interactions at runtime. It also offers a marketplace of vetted add-ons. The company was founded in February 2026 by Unit 8200 alumni Yair Saban (CEO) and Niv Hoffman (CTO). It came out of stealth in September 2026 with $50M in seed funding, a $10M round led by Sequoia and a $40M round led by Greenoaks. It reports more than 20 enterprise customers, mainly in financial services and pharmaceuticals, and about 40 employees.
