Summary: Practical guidance for matching FortiGate NGFW models to security, throughput and connectivity requirements.
Selection criteria to consider
When selecting a FortiGate NGFW, evaluate:
- Security requirements
- Expected throughput and inspection needs
- Interface connectivity and port types
- Redundancy requirements (WAN, power, IPsec VPN tunnels, device)
- Ease of migration from existing systems
Throughput and inspection capacity
FortiGate models vary significantly in available throughput. This affects performance when enabling security inspection features such as SSL decryption and deep packet inspection.
Below is a snapshot of real performance values from three FortiGate models across the Branch and SMB range:
| Model | Firewall Throughput | Threat Protection Throughput | SSL Inspection Throughput |
|---|---|---|---|
| FortiGate 30G | 4 Gbps | 500 Mbps | 400 Mbps |
| FortiGate 80F | 10 Gbps | 900 Mbps | 715 Mbps |
| FortiGate 200G | 39 Gbps | 6 Gbps | 7 Gbps |
Use inspection throughput (not just raw firewall throughput) as the primary sizing metric if security services will be enabled.
Connectivity and hardware variants
FortiGate appliances differ in WAN/LAN port counts and optional hardware variants such as PoE, Wi-Fi, LTE/5G or built-in storage. Confirming connectivity needs up front prevents the need for extra switching hardware.
Licensing and high availability
For high-availability deployments, each appliance in the cluster must have its own license and support contract. Licensing only the primary device is not sufficient.
Security service bundles
Fortinet offers security bundles that combine services such as intrusion prevention, malware protection, URL/DNS filtering, application control and support. Select the bundle based on which services will be enabled.
Migration support
Fortinet offers migration services to convert existing configurations to FortiGate, which reduces manual configuration effort and error risk.
