Cisco ASA Firewall Review

The various NGFW and NGIPS features are valuable, but the option to use ASA to decrypt SSL would be an improvement.

What is most valuable?

NGFW: VPN (IPSec, SSL), NAT (provides great flexibility)

NGIPS: Application visibility, file policies (store files), network discovery, correlation features

What needs improvement?

SSL decryption for modules. Although I think it is better to separate SSL decryption as a service from the software module since it requires additional hardware, but I think it would be great if there is an option to use the ASA (not the software module) to decrypt the SSL.

Ex: Add a license to decrypt SSL traffic on the ASA itself. The ASA already supports SSL VPN. So if SSL decryption can be integrated that would be nice.

For how long have I used the solution?

5 years+

What was my experience with deployment of the solution?

Basic setup is easy, but if you need to do some advanced stuff, it can be intuitive, but some things require some kind of tutorial to understand how it can be done. Good thing is that this device is becoming popular and there are many 3rd party free tutorials and guides that can help.

What do I think about the stability of the solution?

I heard about defect that were encountered by my colleagues, but not something that cannot be fixed using an upgrade.

What do I think about the scalability of the solution?

Clustering is available for ASA with firepower services.

Also for firepower appliances, there is stacking available for some models.

How are customer service and technical support?

Customer Service:

Great support. The engineers know what they are doing.

Technical Support:


Which solution did I use previously and why did I switch?


How was the initial setup?

Well, it is straight forward as long as you understand the components available.

ASA can be configured using the CLI or ASDM.

For the Firepower you will need to use a FireSIGHT as a management solution.

Since you will be using two GUIs, I wouldn't call it straight forward.

Which version of this solution are you currently using?
