Curation Review
✔ Pros:Five 2.5GbE ports give multi-gig WAN and LAN connectivity; Quad-core ARM CPU and 3 GB RAM handle IDS/IPS at up to 2.3 Gbps on UniFi OS 4.1+; Supports site-to-site IPsec, WireGuard and OpenVPN; Optional NVMe storage enables UniFi NVR use; Low price compared with business-class firewalls; Compact desktop form factor with low 16.1 W power draw
✘ Cons:Ubiquiti does not publish firewall, IPsec VPN or session-capacity figures; IDS/IPS rating differs between sources (1.5 Gbps older, 2.3 Gbps newer); Third-party reviews report only about 500 to 1,000 Mbps for WireGuard, which limits VPN-heavy use; No PoE ports and no SFP+ or 10G uplink; Manages only 30+ UniFi devices, so it does not scale to large deployments; Requires UniFi OS 4.1+ for the 2.3 Gbps IDS/IPS figure
✔ Pros:Strong 39 Gbps firewall throughput for a mid-size enterprise edge device; 11 million concurrent sessions and 400,000 new TCP sessions/sec; 8x 10GE SFP+ ports for high-speed uplinks and LAN; bundled FortiGuard security services (IPS, antivirus, SD-WAN) available via licensing; reviewers describe stable performance and IPsec tunnels that are easy to build and interoperate with other vendors' devices; compact 1U form factor
✘ Cons:High hardware and licensing costs, with bundles significantly above the hardware-only price; threat prevention throughput (6 Gbps) is far below rated firewall throughput, so security-inspection-heavy deployments need careful sizing; no 25GbE ports; firmware updates have been reported to introduce bugs affecting stability; Fortinet technical support response time and quality are a frequent complaint; licensing model is seen as inflexible; port counts differ across sources, so verify against Fortinet's official datasheet
