What do I think about the stability of the solution?
Cisco Hybrid Mesh Firewall is mostly stable, although there have been times where we have had issues that we have worked on.
Regarding the downtime experienced, one of the main issues is with the complexity of my environment. With different types of traffic coming in, we have noticed issues with streaming-related traffic where some traffic gets pinned onto certain CPU cores.
How are customer service and support?
I have worked with Cisco's customer support for the firewalls, and they are quite great.
My experience with Cisco's customer support is positive. As and when we need support, we receive it, and I have not had any challenges with the TAC or the support. It is good.
What other advice do I have?
At the moment, I do not use Cisco AI Defense, but I may consider it later.
I am here to evaluate the potential addition of Cisco AI Defense, although it is somewhat outside my scope. I am primarily here to understand where Cisco is headed in the AI edge, while my higher-ups are here to evaluate.
On a scale of one to ten, with one being worst and ten being best, I would rate Cisco Hybrid Mesh Firewall/Firepower an eight.
I rate it an eight because the product itself is great, but there are some limitations to it, and some features could probably be inherited into the firewalls. My recommendation to others reading reviews on PeerSpot is to understand that while the core product is excellent, you should evaluate whether the current feature set and performance characteristics align with your specific traffic patterns and infrastructure complexity.
Disclosure: My company does not have a business relationship with this vendor other than being a customer.
