What do I think about the stability of the solution?
Rarely.
What do I think about the scalability of the solution?
Yes, before Clustering was introduced.
How are customer service and support?
Nine out of 10.
Which solution did I use previously and why did I switch?
Yes. We changed for no special reason, just to mix things up.
How was the initial setup?
Yes, but you need to read and understand how the device functions before deployment.
What's my experience with pricing, setup cost, and licensing?
Like with all vendors, know what options you require and request the proper license accordingly. Prices are on the same level as competitors.
Which other solutions did I evaluate?
Not really, as all firewalls do most of what enterprises look for. What matters most is the after sales support.
What other advice do I have?
Read, read, read and understand your requirements beforehand.

Gerente de Telecomunicaciones at a financial services firm with 1,001-5,000 employees
The front page of device manager is the most valuable feature. We suffered an attack and the firewall was down repeatedly.
What is most valuable?
The front page of device manager is the most valuable feature because it makes it easy to know the system status.
How has it helped my organization?
It’s hard to say because our equipment was EoS.
For how long have I used the solution?
I have used Cisco ASA for three years.
What do I think about the stability of the solution?
We suffered an attack and the firewall was down repeatedly.
What do I think about the scalability of the solution?
We have to buy more licenses to get more VPN connections.
How are customer service and technical support?
I rate support 7/10.
Which solution did I use previously and why did I switch?
We didn’t have a previous solution. I actually searched after another solution.
How was the initial setup?
Setup was complex because we had not taken a course previously.
What's my experience with pricing, setup cost, and licensing?
Sincerely, I prefer other products with no limit on licensing of VPNs, for example.
What other advice do I have?
You have to find more confidentiality, integrity and availability.

Security Engineer at a tech services company with 501-1,000 employees
FirePOWER mobile is good, but they should make the device accesible from the web.
Valuable Features
- Firewall
- VPN
- FirePOWER mobile
Room for Improvement
They should make the ASA accessible via the web instead of ASDM. Also, a big improvement is needed on the transparent mode.
Use of Solution
I've used it for over six months.
Deployment Issues
There were some issues.
Stability Issues
There have been some issues with Java.
Scalability Issues
There were some issues.
Customer Service and Technical Support
Customer Service:
8/10.
Technical Support:8/10.

Network Engineer at a university with 51-200 employees
Powerful firewall and VPN device that is highly stable with multiple contexts but has latency and NATing issues
Valuable Features:
-Powerful firewall provides multiple contexts.
-Highly stable firewall for campus traffic with no shutdown and zero maintenance compared to the Juniper SRX family which performs like a software firewall after 3 months of operation and did not allow the administrator to login.
-Easy to use both GUI and command line. Also it may be more easily used through a management application like Cisco ASDM
Room for Improvement:
-Latency and delay due to configuration and monitoring of multiple VLANS and traffic
-Increases the delay as the firewall and IPS polices increase
-We faced usually a problem with NATING
Other Advice:
Cisco delivers a powerful firewall -- it’s not just a firewall but also a modular device that can deliver IPS hosting and wireless LAN controller as well. It also provides site to site VPN and remote access VPN services.

Network Engineer at a tech services company with 201-500 employees
Easy to operate with good technical support, but needs better logging features
Pros and Cons
- "The command line is the same as it is on the Cisco iOS router."
- "The solution needs to have better logging features."
What is our primary use case?
We primarily provide implementation and maintenance services to our clients.
What is most valuable?
The software itself is very simple.
The solution is easy to operate. It's not overly complex.
The command line is the same as it is on the Cisco iOS router.
The technical support is very helpful and responsive.
What needs improvement?
The solution needs to have better logging features.
Cisco needs to migrate its ASA Firewall to a management console or to a web console.
For how long have I used the solution?
I've been working with the solution for six years at this point.
What do I think about the stability of the solution?
The solution is largely stable. Once we adopted Cisco services, we found that everything was pretty reliable. There aren't bugs or glitches. It doesn't crash or freeze. It's quite good.
What do I think about the scalability of the solution?
The scalability is a problem as the solution has a low throughput.
How are customer service and technical support?
We've been in touch with technical support and I've always found them easy to reach. They're responsive and helpful. I find their service much better than, for example, Fortinet or Palo Alto. Overall, we're satisfied with Cisco with respect to their technical support.
Which solution did I use previously and why did I switch?
We have some experience working with Palo Alto and Fortinet solutions as well.
What's my experience with pricing, setup cost, and licensing?
While I don't have the exact pricing of the solution, it's my understanding that Cisco is rather costly. It's not the cheapest option on the market. It's expensive. It's more costly, for example than Palo Alto.
What other advice do I have?
We have a gold partnership status with Cisco, however, we are also partners with companies such as Fortinet and Palo Alto.
For a next-generation firewall, I would likely recommend Palo Alto. However, if a company had the budget, I would recommend Fortinet. That said, for a VPN gateway, I would recommend Cisco ASA.
In general, I would rate Cisco's ASA Firewall at seven out of ten.

IPS features can be accessed from a separate interface
What is most valuable?
I enjoy the interface of Cisco products, especially the CLI version. I think the IPS feature in the product is best compared to products of other vendors. All the IPS features can be accessed from a separate interface, e.g., Cisco IDM.
How has it helped my organization?
We are an educational institute, and we are required to block many websites that are not suitable for students and teachers. Most of the sites, like YouTube uses an https version, thus blocking with IP address was becoming problematic. Moreover, certificate domains for Gmail and YouTube are the same. But the IPS feature in this product helps us to overcome this limitation.
What needs improvement?
Pricing of this product needs improvement.
For how long have I used the solution?
I have used this solution for two years.
What do I think about the stability of the solution?
I did not encounter any issues with stability.
What do I think about the scalability of the solution?
I did not encounter any issues with scalability.
How are customer service and technical support?
I would give technical support a rating of a nine out of 10.
Which solution did I use previously and why did I switch?
I worked with Cyberoam and Fortinet UTM at my previous job. When I joined my present company, they were already using the Cisco ASA solution. But my present company may switch to other vendors, especially Fortinet, because of the license renewal price.
How was the initial setup?
As I enjoy working on CLI, I would say that the initial setup was not complex.
What's my experience with pricing, setup cost, and licensing?
License and appliance costs are more expensive as compared to other vendors on the market.
What other advice do I have?
If your company is small or mid-range, it is better to go with other vendors, because of the pricing.

Corporate Information Security Officer
A standard rule based firewall that has solved many remote access problems.
What is most valuable?
It's a standard rule based firewall for us. The AnyConnect VPN has solved a lot of remote access problems. High availability is good. It will fall back to the other ASA without any disruptions.

It has secured our DMZ.

I would like to see the following made easier:

Sometimes we suffer from older versions, such as objects, object groups, and aliases (name).

We have been using the solution for nine years.
What do I think about the stability of the solution?
We did not encounter any stability issues.

We didn't evaluate any alternative products.
