Company History
Founded 2000 in Sunnyvale, California
Fortinet began as Ken Xie and Michael Xie's second major act in network security after Ken Xie's earlier NetScreen experience. The founding insight was that enterprise networks were becoming too fast and too complex for security tools that relied only on general-purpose processing. Fortinet built FortiGate appliances and FortiOS around purpose-built security processing, then expanded that base into FortiGuard subscriptions, secure networking, SASE, cloud security, and security operations. The company is now less a single firewall vendor than a cybersecurity platform built on an installed base of high-performance network-security devices.
Fortinet possesses a technical, pragmatic founding story, rooted in the relentless ambition of two brilliant brothers who recognized a fundamental flaw in the early architecture of internet security. The company was founded in 2000 in Sunnyvale, California, by Ken Xie and his brother Michael Xie. Ken Xie was already a legendary figure in the early cybersecurity industry. While he was an engineering student at Stanford in the 1990s, he built a software firewall in his garage and founded NetScreen Technologies. NetScreen was successful because it utilized hardware-accelerated firewalls, and it was eventually acquired by Juniper Networks for a $4 billion. However, following his success with NetScreen, Ken Xie realized the cybersecurity landscape was changing. The proliferation of complex viruses and spam in the early 2000s meant that a simple firewall (which just blocked IP addresses) was insufficient. Companies were being forced to buy expensive, separate appliances for every single problem (one box for a firewall, one box for antivirus, one box for VPN). This was inefficient, expensive, and slow for the network. Ken and Michael Xie founded Fortinet with a foundational, vision: Unified Threat Management (UTM). They believed they could build a single, advanced hardware appliance that could perform every single security function simultaneously without slowing down the network. Because Michael Xie was a brilliant chip designer, they achieved this by designing custom ASIC chips specifically built to inspect network traffic. Their pragmatic, engineering-first approach disrupted the cybersecurity establishment, transforming Fortinet from a small startup into the dominant provider of network security hardware for millions of businesses globally.
Michael Xie helped build Fortinet's engineering culture and product architecture, supporting the company's expansion from FortiGate firewalls into a broader cybersecurity platform.
