Fortinet FortiGate 51G-5G Firewall, Hardware Only (FG-51G-5G)

The FortiGate 51G-5G (FG-51G-5G) stacks three capabilities into one compact chassis: the G-series security engine, an embedded 5G/LTE cellular WAN module, and 64 GB of onboard SSD storage. For branch deployments that need cellular WAN backup and local log retention simultaneously — without adding separate devices for either — this is the single-SKU answer.

Hardware Specifications

Three Features, One Box

The 5G WAN module connects as a cellular WAN interface in FortiOS — SD-WAN policies can route over cellular automatically when the primary fixed ISP degrades. The 64 GB SSD stores logs locally, eliminating cloud dependency for forensics and compliance. And the G-series engine — 2.25 Gbps IPS, 1.3 Gbps SSL inspection — handles the throughput of today’s gigabit business internet connections without requiring inspection to be disabled.

Each of these features would normally require a separate device or subscription add-on. The 51G-5G delivers all three as built-in hardware.

Hardware Only — What That Means

This listing is the appliance without subscription. A SIM card is also not included. FortiCare and FortiGuard services are required — license options use the FC-10-F51G5- prefix, with 1-Year UTP (FC-10-F51G5-950-02-12) and Enterprise (FC-10-F51G5-809-02-12) available separately on DataCenter360.ca.

Who Deploys the FG-51G-5G

MSPs managing branch offices for compliance-sensitive clients — healthcare, legal, financial services — frequently choose this model when they need cellular WAN backup and local log retention at each site. It is also the right pick for branch locations in urban or suburban Canadian markets where 5G coverage from Bell, Rogers, or Telus is reliable enough to serve as genuine WAN backup. A nano-SIM from your preferred carrier is all that is needed to activate the cellular interface.

Moving Up: FortiGate 70G

For sites that outgrow the 51G-5G in throughput or port count, the FortiGate 70G (FG-70G) is the next G-series model with higher interface density and session capacity.
