Description
Fortinet FortiGate 400F Series (FG-400F / FG-401F / -DC)
High-performance 1RU NGFW + Secure SD-WAN + ZTNA + segmentation, designed for larger branches / campus edge / data-centre edge where you want serious inspection throughput plus a lot of 10G.
At-a-glance performance (Enterprise Traffic Mix)
-
IPS: 12 Gbps
-
NGFW: 10 Gbps
-
Threat Protection: 9 Gbps
-
SSL Inspection (IPS avg HTTPS): 8 Gbps
-
IPsec VPN (512B): 55 Gbps
-
SSL-VPN: 3.6 Gbps
-
Recommended concurrent SSL-VPN users: 5,000
Plain English: this is a big jump up from 200F/100F when customers say we need deep inspection on 10G links without the firewall becoming the bottleneck.

-
16 x GE RJ45 (hardware accelerated)
-
2 x GE RJ45 MGMT/HA ports (plus console/USB)
