Fortinet FortiGate 120G Firewall, Hardware Only (FG-120G)

Branch and mid-size enterprise sites that have outgrown a 90-class firewall, but do not need a rack full of 200-series gear, land on the FortiGate 120G (FG-120G). It pairs Fortinet’s SP5 SoC acceleration with four 10GE SFP+ slots and a 480 GB onboard SSD in a single 1RU chassis, so a regional office can terminate multi-gigabit fibre, inspect encrypted traffic, and keep its own logs without leaning on the cloud.

What you get in the box

This listing is the appliance on its own: the FG-120G unit with its dual built-in AC power supplies and rack ears. FortiOS is pre-installed. No FortiCare or FortiGuard subscription is bundled at this price, which is what keeps the hardware line clean for buyers who already hold licensing or plan to add it separately.

Hardware Specifications

Where the 120G earns its place

The four 10GE SFP+ slots are the headline. They let the firewall sit inline on a 10-gigabit core or terminate fibre WAN links at full speed, and the 8 GE SFP cages add fibre flexibility on top of the 16 copper ports. With 3 Gbps of SSL inspection the unit can decrypt and scan the majority of a saturated gigabit link rather than waving HTTPS traffic through uninspected. The 480 GB SSD holds local logs and reports on the box, which matters for sites with audit or retention requirements and patchy cloud connectivity. Dual power supplies in a 1+1 arrangement keep the appliance up through a single PSU failure.

Hardware alone, or a bundle

The firewall enforces policy out of the box, but the FortiGuard services that block live threats, antivirus, IPS, web and DNS filtering, application control, run on an active subscription. If you do not already carry licensing for this unit, a UTP or Enterprise bundle that packages the hardware with FortiCare support and FortiGuard services is usually the better value than buying the appliance and a subscription separately. The linked options below cover both routes.

Who runs a 120G

It fits distributed enterprises standardizing branch security, mid-market companies consolidating routing, SD-WAN, and threat protection into one device, and managed service providers deploying a repeatable 1RU platform across client sites. Anything pushing past its session table or 10GE slots is a candidate for the 200-series.

Moving up

Need more interface density, deeper session capacity, or higher inspected throughput? The FortiGate 200F and 200G step up to that tier. Staying in the 120 class but want onboard storage doubled and the same port layout, look at the FG-121G sibling.
