Our primary use case is for perimeter security.
We are using the enterprise version. Cisco has many versions. Maybe we are using the old version of ASA because it needs to be the freeware. In each freeware, there are different types of things. Maybe it is the standard version because the other version cost a lot. I need to combine it with another solution like an open source standard solution of the ASA firewall from Cisco.
Firewalls are about blocking. ASA is for blocking, but it does not have the intelligence like Fortinet to detect attacks. If I could use ASA to detect attacks, maybe we could buy another service from Cisco although it's very expensive. I would choose Fortinet, but my clients like ASA support. I prefer Fortinet because Fortinet has a UTM and it's a good firewall.
In terms of what could be improved, the UTM part should be more integrated for one price, because if you buy ASA from Cisco, you need to buy another contract service from Cisco as a filter for the dictionary of attacks. In Fortinet, you buy a firewall and you have it all.
I would like to see all the features like Fortinet has. If I buy ASA, I would like to see a Fortinet-like interface.
It would be good if Cisco could improve their web interface to configure the equipment. Cisco is very reliable and very secure, but has to compete with Fortinet which is very hard.
On a scale of one to ten, I would give Cisco ASA Firewall a nine.
I have been using Cisco ASA Firewall for about 15 years.
We have maybe 100 - 200 end users using the solution.
I would give their technical support an eight out of ten because of their response time.
Let me give an example. When I have a problem, and I contact support, maybe there is a guy from India or from another country answering me. This is very slow. The people look at the ticket and increase the time for response.
The initial setup is easy. Firewalls are like programming. If you know programming, you know every language. Firewalls are the same. If you know the security and blocking the perimeter, it's the same for all the firewalls. The difference with the different firewalls are the functionalities. Learn the functionalities in every brand.
My advice to anyone considering Cisco ASA Firewall is that you need a lot of money to implement the Cisco solution. But it's a good solution. If you want to go to Cisco, you need a lot of money.
