I find the integration with Cisco products in Cisco Secure Firewall most valuable because the majority of the features are equivalent to other OEMs, and the ecosystem integration with Cisco is what I prefer.

The visibility and control capabilities of Cisco Secure Firewall benefit our company by making it easier for us to parse through traffic that is denied or allowed through, and that helps us with troubleshooting, so it does help cut down on troubleshooting.

The central management feature makes it easier to configure once, push out, and replace firewalls when they go bad. It's nice to have one pane of view, one pane of glass.

The feature of Cisco Secure Firewall that I appreciate the most is its ability to be used via the cloud, so we don't have to deploy service engineers on-site at any time.

Regarding stability and reliability, I have experienced false negative alerts with the CS models, which indicate that my switch has gone down when in reality, it has not. That is a fix that is needed.

We tried to look into Z3 models before, but our cybersecurity team found some issues where it was lacking. They found some bugs or loopholes, so we wanted Cisco to address these before we fully roll out the solution. We're trying again, and hopefully, with Cisco's updates, it will be acceptable to us in the near future.

The upgrading process of Cisco Secure Firewall is a long process on a per-firewall basis, and it would be nice if that could be improved. One firewall can take two to two and a half hours to upgrade, so we end up having to watch it.
