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 hardware has reached end of life and is no longer sold. These FortiGuard and FortiCare renewals keep an installed unit licensed and supported. Licensing is delivered electronically worldwide.

The FortiWiFi 51E is an end-of-life compact desktop next-generation firewall from Fortinet's 50E series, built for small offices and branches that need enterprise-grade protection, integrated Wi-Fi and a 32 GB onboard SSD for local logging in a fanless chassis. It delivers 2.5 Gbps firewall throughput, 220 Mbps NGFW, 160 Mbps of threat protection and 1,800,000 concurrent sessions across seven GE RJ45 ports, with a built-in dual-band 802.11 a/b/g/n access point, SD-WAN and FortiGuard security in FortiOS.
The 51E reached end of life, so the hardware is no longer sold; you can still renew its FortiGuard security services and FortiCare support to keep an installed unit protected, using the renewal options below. When you are ready to replace it, the currently-shipping FortiWiFi 50G is the direct successor — Wi-Fi 6 and roughly 2x the firewall throughput with far higher NGFW and threat protection — and the FortiWiFi 70G steps up further for growing sites. See the upgrade path below.

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.
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.

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.
