When choosing Fortinet FortiGate, you must know your network size and use case. Choose a FortiGate model that fits your current network and allows for future growth. For small offices and branches, you can use 40, 48, 40F, and 60F series. For medium offices, 80F and 100F are suitable. For large enterprises, you need 200F, 400F, 600F. For data centers, 1000F is recommended.
It's advisable not to buy a model that barely fits; choose one with headroom for future expansion. Always check key specs based on your needs, such as firewall throughput, threat protection throughput, VPN throughput, maximum concurrent sessions, and ports. Check if you need SFP, PoE, or 10G ports.
Consider the features you actually need, such as SD-WAN, SSL VPN, application IPS, AV scanning, Wi-Fi AP support, or central management. If you need central management, you can use FortiManager. Look for FortiOS version compatibility as the F-series offers clear advantages. Make sure your team can operate and manage it with experienced Fortinet engineers.
My review rating for Fortinet FortiGate is three out of ten.
