FortiGate by Fortinet is a next-generation firewall (NGFW) platform that combines network security, SD-WAN, and networking capabilities through a unified operating system called FortiOS. Built on patented security processors (SPUs) and custom ASICs manufactured by partners including Toshiba and Renesas, it delivers hardware-accelerated security performance up to 520 Gbps threat protection throughput. The system provides AI/ML-powered threat protection through FortiGuard Labs, with comprehensive security features including deep packet inspection, SSL/TLS inspection, intrusion prevention, web filtering, antimalware, DNS security, and cloud sandbox analysis. FortiGate supports multiple deployment options including physical appliances, virtual machines (FortiGate-VM), and cloud-based implementations across major providers like AWS, Azure, Google Cloud, and Oracle Cloud. It integrates with the Fortinet Security Fabric architecture for coordinated security operations and enables consistent policy enforcement across on-premises, cloud, hybrid, and converging IT/OT/IoT environments. The platform includes advanced networking features such as SD-WAN with application steering, zero trust network access (ZTNA), and dual 5G modem support for operational technology environments.
