- Cisco Secure Firewall
Best for: Cisco networks wanting a firewall that fits in
It is on the list because it slots into Cisco networks and sends its data to Splunk, so your network and security teams keep one vendor and one log pipeline. That suits mid-market and enterprise shops with a lot of Cisco already in place. Its published detail is thin, so ask Cisco for detail on threat prevention, cloud firewalls and the management console before you compare it with the rest of the list.

- Fortinet FortiGate Next-Generation Firewall
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.
