OVERVIEW

What the FortiGate 51G is for

The FortiGate 51G is a compact desktop next-generation firewall for small offices, retail, and branch sites. It pairs the standard 50G platform with a 64 GB onboard SSD for local logging and storage. Built on Fortinet's SP5 secure SD-WAN ASIC, it delivers 1.1 Gbps of threat protection, 5 Gbps firewall throughput, 720,000 concurrent sessions, and 1.3 Gbps of SSL inspection in a fanless five-port desktop unit. It connects over standard Gigabit Ethernet and runs FortiOS with built-in SD-WAN and ZTNA enforcement, with no add-on license needed for those features. The 64 GB onboard SSD is the one difference from the base 50G: it keeps logs and reports on the device, useful at branch and remote sites that need local retention without a separate logging appliance.

Compare the FortiGate 50G line

All 50G-series models share the same SP5 platform and performance. They differ by WAN connectivity (Ethernet, SFP fiber, PoE, 5G cellular, or VDSL/ADSL) and storage. The ‘1’ models – 51G, 51G-SFP-PoE and 51G-5G – add a 64 GB onboard SSD for local logging; FortiWiFi models add an integrated Wi-Fi 6 access point.

COMPARE THE LINEUP

How the 51G compares to the 30G and 70G

The 51G sits in the middle of the desktop G-series. Step down to the 30G for the smallest sites, or up to the 70G for higher throughput and session capacity. Same FortiOS and FortiGuard services across the range.

FAQ

FortiGate 51G - frequently asked questions

The 51G is a current-generation ‘G’ series FortiGate built on the SP5 secure SD-WAN ASIC, fully supported with active FortiGuard and FortiCare subscriptions. It is the base 50G desktop model with a 64 GB onboard SSD.

The onboard 64 GB SSD provides local storage for logging and reporting, so logs and reports are retained on the device. The base FortiGate 50G has no onboard storage; the 51G is the variant that adds it.

The 51G delivers 5 Gbps firewall throughput, 2.25 Gbps IPS, 1.25 Gbps NGFW, 1.1 Gbps threat protection, and 1.3 Gbps SSL inspection, with 720,000 concurrent sessions and 85,000 new sessions per second, identical to the 50G platform.

The 51G adds a 64 GB onboard SSD for local logging and storage. Everything else is the same: the same fanless chassis, five Gigabit Ethernet ports, SP5 ASIC, and security performance.

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