OVERVIEW

What the FortiGate 121G is for

The FortiGate 121G is the storage-equipped model of the 120G line. It runs the same Fortinet SP5 SPU platform and 120G-class performance - 2.8 Gbps threat protection, 39 Gbps firewall throughput, 3 million concurrent sessions and 3 Gbps SSL inspection - and adds a 480 GB onboard SSD so the appliance can store local logs, reports and traffic captures without a separate collector. The 1U chassis carries 16 Gigabit RJ45 switch ports, eight Gigabit SFP slots and four 10GE SFP+ FortiLink slots, with dual built-in AC power supplies for redundancy. It runs FortiOS with built-in SD-WAN and ZTNA enforcement at no extra license cost. The 480 GB SSD is the difference from the 120G; step down to the 90G desktop for smaller sites, or up to the 200G for higher session capacity.

Compare the FortiGate 120G line

The 120G and 121G share the same SP5 platform, ports and 120G-class performance. They differ by onboard storage: the 121G adds a 480 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 121G compares to the 90G and 200G

The 121G sits in the 1U G-series, between the 90G desktop and the 200G. Step down to the 90G for smaller branches, or up to the 200G for higher session capacity and data-center-edge throughput. Same FortiOS and FortiGuard services across the range.

FAQ

FortiGate 121G - frequently asked questions

The 121G 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 120G 1U line.

The 121G adds a 480 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 120G.

The 121G delivers 39 Gbps firewall throughput, 5.3 Gbps IPS, 3.1 Gbps NGFW, 2.8 Gbps threat protection and 3 Gbps SSL inspection, with 3 million concurrent sessions and 140,000 new sessions per second.

16 Gigabit RJ45 switch ports plus a dedicated MGMT and HA RJ45 port, eight Gigabit SFP slots and four 10GE SFP+ FortiLink slots, with one USB port and one RJ45 console port. Dual built-in AC power supplies provide redundancy.

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