Good throughput, with one-of-a-kind support, that is scalable
Pros and Cons
- "The most valuable features of this solution are the integrations and IPS throughput."
- "The price and SD-WAN capabilities are the areas that need improvement."
What is our primary use case?
I am a pre-sales engineer, and I do comparisons based on my customer's requests.
What is most valuable?
The most valuable features of this solution are the integrations and IPS throughput.
What needs improvement?
The price and SD-WAN capabilities are the areas that need improvement.
In the next release, I would like to see more of the FortiGate features added. FortiGate is compatible with Cisco ACI, but I can't see Firepower with Security Fabric. For example, if I had Fortinet activated, could I integrate with it?
For how long have I used the solution?
I have familiar with the Next Generation firewalls for two years, and six years with firewalls in general.
What do I think about the stability of the solution?
It's a stable product.
What do I think about the scalability of the solution?
It's scalable indeed.
Our clients are SMB Enterprise.
How are customer service and technical support?
It's just a fact, nothing is better than Cisco technical support.
Which solution did I use previously and why did I switch?
Previously, I was working with Fortinet. I would most likely recommend Fortinet, because of the price and the security fabric integration with other products. It's scalable as well, and all of the FortiGate features are useful.
It's very easy to implement and it's very easy to administrate.
How was the initial setup?
The initial setup was straightforward. With other vendors, it is easier, but it was straightforward.
What's my experience with pricing, setup cost, and licensing?
This product is expensive.
What other advice do I have?
I would rate this solution an eight out of ten.
