Purpose-built security hub

The FortiGate 120G is a rack-mountable firewall appliance designed as the central security hub for distributed enterprise sites. It combines next-generation firewall capabilities with integrated SD-WAN and zero-trust network access enforcement in a single operating system. The bundle includes one year of FortiCare Premium support and FortiGuard Enterprise Protection services.

Suits multi-site enterprises, not small offices

This appliance suits organisations that need coordinated threat protection across many locations with up to 5000+ users and 10 Gigabit Ethernet uplinks. It is not for teams that require only basic internet gateway functions or sites that lack rack infrastructure and redundant power planning.

Verify rack space and uplink modules

Before ordering, confirm the 1.73 x 17 x 10 inch chassis fits your rack depth and that 40 W maximum power draw matches available circuits. Check whether the eight SFP and four 10GE SFP+ FortiLink slots cover your fibre uplink needs or if additional transceivers must be sourced separately.

Questions about this item

What rack space and power connections do I need to install the FortiGate 120G?

The appliance fits a 1U rack slot measuring 1.73 x 17 x 10 inches and ships with dual non-swappable AC power supplies for 1+1 redundancy, each accepting 100-240VAC at 50-60Hz.

Can I keep using my existing 1 Gbps copper switches and 10 Gbps fibre uplinks with the 16 GE RJ45 and 4 SFP+ FortiLink ports?

Yes, the 16 GE RJ45 ports connect directly to 1 Gbps copper gear while the 4 SFP+ FortiLink slots support 10 Gbps fibre modules for uplinks or stacking.

How do I verify the firewall is processing traffic at the rated 3.1 Gbps NGFW throughput after deployment?

Monitor the dashboard’s real-time throughput widgets and run the built-in traffic generator against the 1518, 512 and 64 byte UDP packet sizes to confirm sustained performance near the published 3.1 Gbps NGFW figure.
