Fortinet FortiGate 400E (FG-400E) Next-Generation Firewall – 32 Gbps Firewall, 5 Gbps Threat Protection

Next-generation firewall and Secure SD-WAN for mid-size enterprises.

The Fortinet FortiGate 400E (FG-400E) is a 1RU rack-mount next-generation firewall that combines threat protection, Secure SD-WAN and IPsec VPN on FortiOS. With 32 Gbps firewall and 5 Gbps threat protection throughput, it suits mid-size enterprises, campus edges and regional data centers.

Why Basic Routers and Legacy Firewalls Leave Networks Exposed

Most attacks now arrive inside encrypted web traffic, cloud applications and phishing links. A basic router with port filtering cannot see any of that, and older firewalls slow to a crawl when IPS and antivirus inspection are switched on, forcing teams to choose between security and speed.

The FortiGate 400E uses Fortinet’s purpose-built security processors to inspect traffic in hardware. That is why it can sustain 7.8 Gbps of IPS and 5 Gbps of full threat protection (IPS, antivirus, application control) while still forwarding 32 Gbps of firewall traffic.

FortiOS also includes Secure SD-WAN at no extra cost: the firewall measures latency, jitter and packet loss on each internet link and routes applications like Microsoft 365 or VoIP over the best path. Branches connect back to head office with 20 Gbps of IPsec VPN throughput.

Security Fabric Integration

The FortiGate 400E is the hub of the Fortinet Security Fabric. Through FortiLink it manages FortiSwitch switches and FortiAP access points from the same FortiOS console, and it shares threat intelligence with FortiAnalyzer, FortiClient and FortiSandbox for coordinated response.

Rack-Ready Hardware for the Server Room

The FortiGate 400E is a 1RU rack-mount appliance (power: Single AC, optional second supply). Its 18 x GE RJ45 + 16 x GE SFP interfaces give room for multiple WAN links, server segments and high-availability connections.

How to Set Up the Fortinet FortiGate 400E

1. Place the appliance on a desk or mount it in a rack, connect power, and connect your internet link to a WAN port.
2. Connect a PC to an internal port, open https://192.168.1.99 (the default management address), and sign in with the default admin account to set a new password.
3. Run the setup wizard to configure WAN, LAN, DNS and firewall policies, then register the device to activate FortiGuard and FortiCare services.
4. Enable security profiles (IPS, antivirus, web filtering, application control), set up SD-WAN and VPN, and upgrade to the recommended FortiOS release.
