Notes

All performance figures are stated by Fortinet as maximums and vary with system configuration. Throughput, sessions and VPN figures are identical across the 50G and 51G series - the SSD and the interfaces are what differ.

IPS, application control, NGFW and threat protection figures are measured with logging enabled. NGFW is firewall, IPS and application control; threat protection adds malware protection.

IPsec VPN performance is tested with AES256-SHA256. SSL inspection figures are an average across HTTPS cipher suites.

Part numbers are Fortinet catalogue SKUs listed for reference. Availability, term and lead time are confirmed at quote.

Wireless appliances ship under a region code - the part numbers above are the Region A variant sold in Canada. Fortinet lists codes A, B, D, E, F, I, J, N, P, S, V and Y.

The datasheet lists maximum current, power consumption and heat dissipation for the FortiWiFi 50G and 51G as TBA. We confirm them on request.

Overview

FortiWiFi 51G

Wi-Fi 6 and a 64 GB SSD on the 50G chassis - the fullest configuration of the copper series.

What the 51G Adds

The 51G is the 50G with a 64 GB SSD fitted. That storage is what lets the appliance keep logs locally rather than shipping every event off-box - useful when the WAN is the thing you are troubleshooting, when a retention requirement has to be met on site, or when FortiAnalyzer is not part of the deployment. Throughput, session capacity, VPN figures and the port layout are identical to the equivalent 50G.

Converged Next-Generation Firewall and SD-WAN

The FortiGate 50G series integrates firewalling, SD-WAN, network controller and security in one appliance, built for small environments that still need enterprise-grade inspection. It runs on FortiOS, the converged networking and security operating system, so one platform covers both sides of the deployment and integrates with the rest of the Fortinet Security Fabric.

Hardware Built to Be Trusted

Every 50G carries a Trusted Platform Module that generates, stores and authenticates cryptographic keys, and a signed firmware hardware switch - a physical switch, set by default to the highest security level, which ensures only validated FortiOS firmware can be loaded. FortiLink lets a FortiSwitch be managed as a logical extension of the firewall, and the FortiLink port can be reconfigured as a regular port when it is not needed.
