Max Sessions: 3,000,000 concurrent TCP (some listings cite 1,500,000)
New Sessions/sec: 124,000 (TCP)
Interfaces: 2x shared-media WAN pairs (each RJ45 10/5/2.5/1 GE or SFP+/SFP 10GE/GE); 8x GE RJ45 internal; 1x RJ45 console; 1x USB
Form Factor: Desktop
Curation Review
✔ Pros:Strong firewall throughput of 28 Gbps for a desktop-class appliance; 25 Gbps IPsec VPN throughput; Supports 200 gateway-to-gateway and 2,500 client-to-gateway IPsec tunnels; Flexible WAN options with shared RJ45 2.5G/5G/10G and SFP+ 10G pairs; 124,000 new TCP sessions per second; Part of the FortiOS ecosystem with centralized management and Fortinet security services
✘ Cons:Threat prevention throughput (2.2 Gbps) is far below the headline firewall figure once security inspection is enabled; SSL VPN removed in FortiOS 7.2.12, 7.4.8 and 7.6.1 (7.0.x footnote applies); No PoE variant, so it cannot power PoE devices; Premium price relative to small-office alternatives, with security subscriptions needed on top of hardware; Concurrent session figure is inconsistent across sources (1.5M vs 3M)
✔ Pros:25G SFP28 and 10G SFP+ uplinks at a gateway price point; 23.5 Gbps routing throughput; 1 million concurrent sessions; 18-core ARM CPU with 16 GB RAM; hot-swappable redundant PSUs; supports 500+ UniFi devices and 5,000+ clients; manages through UniFi Network controller with a single pane of glass
✘ Cons:IPsec VPN throughput of 580 Mbps is low for a gateway at this price; IDS/IPS throughput of 12.5 Gbps halves routing performance when threat inspection is enabled; SSL/TLS inspection is limited to about 10,000 concurrent sessions; port configuration differs across listings and should be verified; frequently out of stock at major US retailers, with a $170 memory surcharge at some resellers; no built-in Wi-Fi, so it depends on separate UniFi APs and switches; reviewers cite a steeper learning curve than consumer-grade routers
