- 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 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.
