Fortinet, Inc.
A maker of cybersecurity hardware and software, Fortinet protects computer networks for businesses, governments, and service providers worldwide, with its flagship FortiGate firewall at the center of a broad product family. Founded in 2000 by brothers Ken and Michael Xie, the name blends "fortified" and "network" — and before settling on it, the founders briefly tried Appligation and ApSecure. The "Forti-" prefix now runs through nearly every product, from FortiManager to FortiClient.
