## Our take

What our shortlists say about the one we picked.

### [Fortinet Secure Networking](https://cybersectools.com/tools/fortinet-secure-networking)

Best for: Organizations consolidating NGFW, SD-WAN, and SASE under one vendor

For SMBs, Fortinet is one of the few enterprise-grade NGFW vendors that scales down to smaller environments without a completely different product line. The FortiGate appliances cover everything from small branch offices to large data centers. The managed SOC-as-a-Service option is worth considering if you don't have 24x7 coverage internally.
