Sourcefires' visibility and control have been a great addition to the product
Pros and Cons
- "Sourcefire has been a great addition. The visibility and control have been nice."
- "Sourcefire has been a great addition, and the visibility and control have been nice."
- "If Cisco could stop rebranding, combine all the CLIs/GUIs, and give a consistent experience, this would be great."
- "If Cisco could stop rebranding, combine all the CLIs/GUIs, and give a consistent experience, this would be great."
What is our primary use case?
The primary use case is for edge firewall at multiple locations and remote access VPN. We use these for security and have them integrated with Splunk/QRadar.
How has it helped my organization?
Edge security and Sourcefire have been nice. Sourcefire was a major improvement over the legacy IDS that it previously had.
What is most valuable?
Sourcefire has been a great addition. The visibility and control have been nice.
I also like the active/standby HA.
What needs improvement?
The solution has two separate GUIs and at least three different CLIs (ASA CLI, Sourcefire CLI, and Firepower Management Center CLI). In addition, ASDM plus Firepower Management Center GUIs. If Cisco could stop rebranding, combine all the CLIs/GUIs, and give a consistent experience, this would be great.
Also, AnyConnect is very difficult to manage and use.
For how long have I used the solution?
More than five years.

Pre-sales engineer with 51-200 employees
Provides visibility as well as management and administration capabilities
Pros and Cons
- "I think Cisco has all the solutions: switching, routing, security, they have wireless; you can cover all the devices with Cisco and they have all the network and engineered tools to help resolve the issues that we have."
- "I think Cisco has all the solutions: switching, routing, security, they have wireless; you can cover all the devices with Cisco and they have all the network and engineered tools to help resolve the issues that we have."
- "It needs better documentation for when we present solutions to non-technical people."
- "It needs better documentation for when we present solutions to non-technical people."
What is our primary use case?
We use it as a perimiter firewall and do VPNs and filtering.
How has it helped my organization?
As a reseller, because Cisco includes different companies like Sourcefire, Meraki, and Talos, I think Cisco has a good portfolio for the security business, with their own devices too. For example, we have our firewall, we have a Web security appliance, things like OpenDNS with Umbrella. I think Cisco can cover with all the platforms.
What is most valuable?
All the visibility the device gives us as well as management and administration facilities.
What needs improvement?
It needs better documentation for when we present solutions to non-technical people. They need to bring together all the information, across the various firewalls, so that we can more clearly explain them.
Also, pricing could be better.
What do I think about the stability of the solution?
It's very stable.
What do I think about the scalability of the solution?
When we implement a firewall we need to be aware of whether it is growing over a short time period or a long time period. I think the scalability, from our implementation, is good because you can use the same configuration for another platform. If you implement on a small platform, it It is easy to implement the same configuration to another, bigger device.
How are customer service and technical support?
I think tech support is a large part of Cisco. It's good, it provides support around the clock, answers problems. I would rate it nine out of 10.
Which solution did I use previously and why did I switch?
SonicWall.
How was the initial setup?
For some things it is very easy, but configuring other things is a little complex. It depends on the use case.
What's my experience with pricing, setup cost, and licensing?
Cisco may be a little expensive but it has everything, and they support very well.
Which other solutions did I evaluate?
Juniper, Fortinet.
What other advice do I have?
I think Cisco has all the solutions: switching, routing, security, they have wireless. You can cover all the devices with Cisco. They have all the network and engineered tools to help resolve the issues that we have. They are really very good devices.
In terms of advice, I would say Cisco is the best company. They're very stable, there aren't too many issues. And when there is an issue they have many engineers who can solve the problem.

Filtering is the best feature
Pros and Cons

- "Filtering is the best feature, as I have gotten used to using it."
- "The IPS and GUI are outdated."
- "It is slowly not supported and other vendors are a few years ahead of Cisco in development."

How has it helped my organization?
It works like a firewall for security reasons.

What needs improvement?
The IPS and GUI are outdated. It is finally getting IPS inside, which will be a big improvement. The GUI is outdated, and they are slowly improving it. We will see if they go in the correct direction. Unfortunately, they usually just follow other vendors.
It is slowly not supported and other vendors are a few years ahead of Cisco in development.
For how long have I used the solution?

What other advice do I have?
Configuration on Firepower is currently madness as you have to redeploy it again with all its configurations if you use it as a module.
