FG-120G AI-Powered Next-Generation Firewall 39 Gbps with 4x 10GE SFP+ Enterprise NGFW Appliance

The FG-120G is an AI-powered Next-Generation Firewall engineered for mid-size enterprises, campus branches and colocation edges that require 39 Gbps firewall throughput without sacrificing inspection depth. Built on Fortinet SP5 security processors and FortiOS, this 1RU appliance converges routing, switching, secure SD-WAN, universal ZTNA and AI-driven threat prevention into one platform, so a single Next-Generation Firewall policy set protects every segment of a hybrid network.

Security inspection runs at wire speed. The FG-120G sustains 5.3 Gbps IPS, 3.1 Gbps NGFW and 2.8 Gbps threat protection, with 3 Gbps SSL inspection so encrypted traffic is decrypted, inspected and re-encrypted in real time. Four 10GE SFP+ FortiLink slots carry uplinks to the core or to FortiSwitch stacks, while 16 hardware-accelerated GE RJ45 switch ports and 8 GE SFP slots connect access devices, servers and WAN links directly. Dual built-in AC power supplies provide 1+1 redundancy for branch sites where a failed PSU must never become an outage.

• Campus and branch edge: the Next-Generation Firewall consolidates firewall, IPS, application control and web filtering, replacing four separate boxes at each site.
• Secure SD-WAN: application-aware steering across MPLS, broadband and 5G links, with 35 Gbps IPsec throughput and 2000 gateway-to-gateway tunnels.
• Data center and colocation segmentation: 4x 10GE SFP+ FortiLink slots and 10 virtual domains isolate tenants, production and management traffic.
• Universal ZTNA and remote access: 500 concurrent SSL-VPN users and 16000 client tunnels with per-application verification.
• OT and IoT protection: device visibility and policy enforcement for segmented industrial and building networks.

• AI-powered threat protection from FortiGuard Labs blocks zero-day, ransomware and AI-generated attacks inline.
• 39 Gbps firewall throughput and 42 Mpps forwarding keep east-west and north-south traffic moving.
• Dual PSU redundancy, 49 dBA acoustics and 40 W maximum draw suit wiring closets without dedicated cooling.
• 4x 10GE SFP+ FortiLink slots cut uplink cost by removing an external aggregation switch.
• One FortiOS fabric for on-premises, cloud and container estates reduces tool sprawl and operating expense.
