Who it is for
Large office or enterprise edge
Multi-gigabit inspection with 10G SFP+ ports and hot-swappable power supplies, in 1U.
SD-WAN and VPN included
SD-WAN and site-to-site and remote-access IPsec VPN are part of FortiOS, so branches can link to head office without another product.
One place to run the network
Manages up to 72 FortiSwitches and 512 FortiAPs through FortiLink, so switching and Wi-Fi are set up from the firewall.
What is included
- FortiGate 400F appliance: 16 x GE RJ45, 8 x GE SFP, 8 x 10GE SFP+ (4 ultra-low latency), 2 x GE RJ45 MGMT/HA.
- Power: Dual hot-swappable AC power supplies (1+1).
- No FortiCare or FortiGuard term. Support, firmware updates and security services such as IPS, antivirus and web filtering need a FortiCare and FortiGuard subscription, sold separately.
Appliance only means no security updates. Without a FortiGuard subscription the FortiGate still routes and filters by policy, but IPS, antivirus and web filtering do not get updates. Most buyers choose the UTP or Enterprise Protection bundle below.
