Best for: Companies wanting SD-WAN and ZTNA built into the firewall
FortiGate earns its spot by folding SD-WAN and ZTNA into the firewall, so many branches can run on one box per site. That fits mid-market and enterprise networks with lots of offices. If you already run separate SD-WAN or ZTNA products, decide first whether you want to merge them.
