Products and research
Products
Fortinet released its first product, FortiGate, a firewall, in 2002, followed by anti-spam and anti-virus software.[6][7] As functions like anti-spam were added, they were made available in a single product along with the firewall and other functions.[15] FortiGate was updated later to use application-specific integrated circuit (ASIC) architecture.[44] The company has used ASIC in several of its products, including to support its SD-WAN features.[45][46]
Initially, FortiGate was a physical, rack-mounted product but later became available as a virtual appliance that could run on virtualization platforms such as VMware vSphere.
In April 2016, Fortinet began building its Security Fabric architecture so multiple network security products could communicate as one platform.[47] Later that year, the company added Security Information and Event Management (SIEM) products.[48] In September 2016, the company announced it would integrate the SIEM products with the security systems of other vendors.[49]
In 2017, Fortinet announced the addition of switches, access points, analyzers, sandboxes and cloud capabilities to the Security Fabric, in addition to endpoints and firewalls.[50][51] Later in 2017, Fortinet created a standalone subsidiary, Fortinet Federal, to develop cybersecurity products for government agencies.[52] Fortinet has received security effectiveness certifications through NSS Labs.[53]
