OVERVIEW

What the FortiGate 91G is for

The FortiGate 91G is the storage-equipped model of the 90G desktop line. It runs the same Fortinet SP5 SPU platform and 90G-class performance - 2.2 Gbps threat protection, 28 Gbps firewall throughput, 3 million concurrent sessions and 2.6 Gbps SSL inspection - and adds a 120 GB onboard SSD so the appliance can store local logs, reports and traffic captures without a separate collector. Two ports are multi-gigabit (10/5/2.5/1 GbE) RJ45 that can be used instead as 10GbE/GbE SFP+ fiber slots, with eight more Gigabit RJ45 ports for internal/LAN. It runs FortiOS with built-in SD-WAN and ZTNA enforcement at no extra license cost, and includes a Trusted Platform Module and Bluetooth Low Energy. The 120 GB SSD is the difference from the 90G; for smaller branches choose the 70G, or step up to the 200G for 1U data-center-edge throughput.

Compare the FortiGate 90G line

The 90G and 91G share the same SP5 platform, ports and 90G-class performance. They differ by onboard storage: the 91G adds a 120 GB SSD for local logging, reporting and traffic capture on the device, at slightly higher power draw. Otherwise the two are identical.

COMPARE THE LINEUP

How the 91G compares to the 70G and 200G

The 91G sits at the top of the desktop G-series. Step down to the 70G for smaller branches, or up to the 200G for 1U data-center-edge throughput and higher session capacity. Same FortiOS and FortiGuard services across the range.

FAQ

FortiGate 91G - frequently asked questions

The 91G is a current-generation ‘G’ series FortiGate built on the SP5 security processing unit, fully supported with active FortiGuard and FortiCare subscriptions. It is the onboard-storage model of the 90G desktop line.

The 91G adds a 120 GB onboard SSD so the appliance can store local logs, reports and traffic captures directly on the device, without a separate FortiAnalyzer or external collector. Everything else matches the 90G.

The 91G delivers 28 Gbps firewall throughput, 4.5 Gbps IPS, 2.5 Gbps NGFW, 2.2 Gbps threat protection and 2.6 Gbps SSL inspection, with 3 million concurrent sessions and 124,000 new sessions per second.

Two multi-gigabit (10/5/2.5/1 GbE) RJ45 ports that can be used instead as 10GbE/GbE SFP+ fiber slots, plus eight Gigabit RJ45 internal ports, one USB port and one RJ45 console port, with Bluetooth Low Energy.

In-stock units ship from Canada with free shipping, usually delivered in 0-1 business days. FortiGuard and FortiCare licensing is delivered electronically worldwide.
