Business Overview

We provide network security solutions, which enable broad, integrated and high performance protection against dynamic security threats while simplifying the IT security infrastructure for enterprises, service providers and governmental entities

worldwide. As of March 31, 2012, we had shipped over 900,000 appliances to more than 10,000 channel partners and to more than 125,000 end-customers worldwide, including a majority of the Fortune Global 100.

Our core UTM product line of FortiGate physical and virtual appliances ships with a set of security and networking capabilities, including firewall, VPN, application control, antivirus, intrusion prevention, Web filtering, antispam and WAN acceleration functionality. We derive a substantial majority of product sales from our FortiGate appliances, which range from the FortiGate-20, designed for small businesses, to the FortiGate-5000 series for large enterprises, telecommunications carriers, and service providers. Sales of FortiGate products are generally balanced across entry-level (FortiGate-20 to -100 series), mid-range (FortiGate-200 to -800 series) and high-end (FortiGate-1000 to -5000 series) models with each product category representing approximately one-third of FortiGate sales. Our UTM solution also includes our FortiGuard security subscription services, which end-customers can subscribe to in order to obtain access to dynamic updates to the application control, antivirus, intrusion prevention, Web filtering, vulnerability management and antispam functionality included in our appliances. End-customers can also choose to purchase FortiCare technical support services for our products. End-customers also often use FortiManager and FortiAnalyzer products in conjunction with a FortiGate deployment to provide centralized management, analysis and reporting capabilities. We complement our core FortiGate product line with other appliances and software that offer additional protection from security threats to other critical areas of the enterprise, such as messaging, Web application firewalls, databases, employee computers and mobile devices. Sales of these complementary products have grown in recent quarters, although these products still represent less than 10% of our revenue.
