The FortiGate 91G combines the FortiGate 90G Series performance with integrated 120GB SSD storage for on-device data storage needs. This compact desktop appliance is built on Fortinet's SP5 ASIC and delivers up to 28 / 28 / 27.9 Gbps firewall throughput (1518/512/64 byte UDP) and up to 25 Gbps IPsec VPN throughput (512 byte). Its versatile connectivity options, including two shared-media WAN ports supporting either 10/5/2.5/GE RJ45 or 10GE/GE SFP+/SFP, help meet demanding bandwidth requirements in modern branch environments.
Running on FortiOS, the FortiGate 91G converges networking and security capabilities into a single operating system, supporting secure SD-WAN and next-generation firewall functions in one appliance. With enterprise-grade performance, strong session capacity, and efficient power usage, the FG-91G is well-suited for distributed enterprise sites that require high-throughput security in a small footprint.
