FAQ

FortiGate 3800G - frequently asked questions

The FortiGate 3800G is a current-generation, top-of-line G-series model, fully supported with active FortiGuard and FortiCare subscriptions available for 1, 3, and 5-year terms.

The 3800G is the top G-series tier: 795 Gbps firewall and 250 Gbps IPS with 4x 400GE QSFP-DD ports in a 3RU chassis, versus the 3500G’s 595 Gbps firewall, 125 Gbps IPS and 2x 400GE ports in 2RU. Choose the 3800G for the highest G-series throughput and port density.

Both offer 400GE QSFP-DD connectivity. The 3800G is the newer G-series (NP7 + CP10) with much higher inspection performance (250 Gbps IPS and 200 Gbps threat protection vs 86 Gbps and 75 Gbps). Choose the 3800G for the latest CP10 engine and maximum inspection throughput.

The optional Hyperscale Firewall license unlocks additional NP7 acceleration, raising concurrent sessions from 200 million to 450 million and new sessions/second from 1.11 million to 7 million. It is a perpetual license for carrier and hyperscale deployments.

The FortiGate 3800G uses Fortinet’s NP7 network processor for firewall and VPN acceleration, and the tenth-generation CP10 content processor for IPS, SSL inspection, and application control. Both ASICs are custom silicon designed by Fortinet.
