- 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.
