What is most valuable?
It was a valuable firewall some years ago but then Palo Alto created the next generation firewall and Cisco needed too much time to create ASA CX. At the moment it has, basically, the same features. In my opinion the most valuable features now are the layer seven capabilities and the new FirePOWER.
For how long have I used the solution?
I've used the devices for over 10 years.
What was my experience with deployment of the solution?
I have never had an issue with my deployments.
What do I think about the stability of the solution?
One of the best things about ASA's is that they are very stable.
What do I think about the scalability of the solution?
With ASA, you can scale to the largest deplyments. As an example, I have installed an ASA in an environment with 80.000 users.
How are customer service and technical support?
Cisco Support is very good, you don't have problems using it. Technical Support
Which solution did I use previously and why did I switch?
I have migrated customers from Cisco's competitors to ASA's.
How was the initial setup?
Once you have the knowledge it is not complex to install an ASA, but it does depend on the network of the customer.
Which other solutions did I evaluate?
Our customers also evaluate PaloAlto.
