OVERVIEW

What the FortiGate 51G-5G is for

The FortiGate 51G-5G is the storage-equipped variant of the FortiGate 50G-5G, adding a 64 GB onboard SSD to the same FortiSP5-accelerated platform. The embedded 3G/4G/LTE/5G modem (with five SMA WWAN antennas) makes it purpose-built for sites where cellular is the primary or backup WAN link — retail locations, construction sites, kiosks, or any deployment where wired broadband is unavailable or unreliable.

The 64 GB SSD enables local log storage and FortiAnalyzer-compatible log retention directly on the device, which is valuable in bandwidth-constrained cellular deployments where forwarding logs to the cloud would consume WAN data. All NGFW capabilities — 1.1 Gbps threat protection, IPS, SSL inspection, Universal ZTNA, and Secure SD-WAN — run on the same FortiSP5 hardware as the 50G-5G.

USE CASES

Where the 51G-5G fits

5G primary or backup WAN
Embedded 5G NR modem eliminates a separate cellular router at sites without reliable wired internet — retail kiosks, construction, remote offices.
Local log storage
64 GB SSD stores FortiOS logs locally, reducing cloud log forwarding over metered cellular data and supporting offline forensic analysis.
Full NGFW on 5G
1.1 Gbps threat protection, IPS, SSL inspection and ZTNA enforcement run on FortiSP5 — the same security stack as the full FG-50G family.
SD-WAN with cellular failover
FortiOS SD-WAN treats the 5G modem as a WAN interface for intelligent steering and automatic failover from wired to cellular on link degradation.

COMPARE THE LINEUP

How the 51G-5G compares to the 31G and 70G

The 51G-5G sits between the 31G desktop and the 70G for throughput. Choose it when you need 5G cellular WAN and local SSD log storage. Step up to the 70G for higher concurrent sessions or PoE switch ports.

FAQ

FortiGate 51G-5G — frequently asked questions

Both models are identical in hardware platform, performance, and 5G connectivity. The FG-51G-5G adds a 64 GB onboard SSD for local log storage. This is particularly valuable in cellular deployments where forwarding logs upstream over a metered connection would consume data allowances. If local log storage is not a requirement, the FG-50G-5G is the lower-cost choice.

The embedded 3G/4G/LTE/5G modem supports the major North American 5G NR Sub-6 GHz bands (n71, n41, n77, n78) as well as LTE/4G fallback. Five external SMA WWAN antennas are included. Check the Fortinet 51G-5G QuickStart Guide or contact DataCenter360.ca for a full band list.
