FortiWiFi 51E has reached end of sale and is no longer available. Current alternatives are listed on our FortiWiFi page.
End-of-life compact fanless desktop next-generation firewall with integrated dual-band Wi-Fi and a 32 GB onboard SSD for local logging, built on Fortinet's purpose-built SoC security processor, with 2.5 Gbps firewall throughput, 1.8 million concurrent sessions and seven GE RJ45 ports plus an 802.11 a/b/g/n access point for small offices and branches. The FortiWiFi 51E hardware is no longer sold — FortiGuard and FortiCare renewals are still available below, and the FortiWiFi 50G is the direct, currently-shipping Wi-Fi 6 replacement.
The FortiWiFi 51E is end of life. The FortiWiFi 50G is the direct, currently-shipping replacement with Wi-Fi 6 and a full-generation jump in throughput and threat protection; the FortiWiFi 70G steps up further. Same FortiOS and FortiGuard services across the range.

Download the FortiGate/FortiWiFi 50E series datasheetSame 50E-series desktop platform and 2.5 Gbps firewall performance. The FortiGate models are wired-only; the FortiWiFi models add an integrated 802.11 a/b/g/n access point, and the 51E variants add a 32 GB onboard SSD for local logging and reporting.
FortiGuard and FortiCare renewal subscriptions for installed FortiWiFi 51E units. Licensing is electronic and delivered worldwide.
Renewal subscriptions for the FortiWiFi 51E may still be available. Request a quote for current options.
No. The FortiWiFi 51E (FWF-51E) has reached end of life and the hardware is no longer sold. You can still renew FortiGuard security services and FortiCare support for an installed unit, and we can quote the current FortiWiFi 50G as a direct replacement.
The FortiWiFi 50G is the direct, currently-shipping replacement — same compact desktop form factor with Wi-Fi 6 and a full-generation jump in firewall throughput and threat protection, well above the FortiWiFi 51E. For more capacity, step up to the FortiWiFi 70G.
Yes, while the model is in its renewal window. Choose a FortiGuard renewal bundle above, or renew individual FortiGuard services and FortiCare support. Licensing is delivered electronically worldwide.
The FortiWiFi 51E has an integrated dual-band 802.11 a/b/g/n access point (2×2 dual-stream) with internal antennas, plus a 32 GB onboard SSD for local logging and reporting. If you need Wi-Fi 6, the currently-shipping FortiWiFi 50G is the replacement.
The FortiWiFi 51E delivers 2.5 Gbps firewall throughput, 350 Mbps IPS, 220 Mbps NGFW, 160 Mbps threat protection and 90 Mbps IPsec VPN, with 1,800,000 concurrent sessions and 21,000 new sessions per second, across seven GE RJ45 ports plus an integrated dual-band 802.11 a/b/g/n access point and a 32 GB onboard SSD, in a fanless desktop chassis.
