Network Engineer at a computer software company with 11-50 employees
Reliable with good WAF and APM modules
Pros and Cons
- "It can scale."
- "The BNS module needs improvement."
What is our primary use case?
Most of the time, we use it as a load balancer. It's for the client’s applications. They then apply WAF policies, of course, if the customer wants, and also an APM solution, like VPN access or Web Box, like a web and reverse protocol. Customers vary in terms of what they want.
What is most valuable?
The WAF and APM are very useful. I like the modules.
The solution has been mostly stable and reliable.
It can scale.
What needs improvement?
The BNS module needs improvement.
For how long have I used the solution?
I’ve been using the solution for the last four and a half or five years. It’s been a while.
What do I think about the stability of the solution?
Most of the time, the stability is okay. For the most part, we don’t have issues with bugs or the solution crashing. It’s fine.
What do I think about the scalability of the solution?
The solution can scale as necessary.
We have a lot of telecom and banking clients that use the solution. I’m not sure how much in total each client has in terms of users. Whoever would be using it would be more on the technical side.
We do plan to increase usage and to continue to offer this to our clients.
How are customer service and support?
We help with the support as well as implementation. If a client runs into issues, they can always talk to us.
I’ve contacted the technical support of F5. However, I haven’t used them that much. They have always been okay. I’ve never had issues with them.
How was the initial setup?
Sometimes the setup is straightforward. Other times it’s more complicated. It depends on the client and the project. How long the deployment takes depends on what they want.
You only need one person to handle deployment and maintenance tasks.
What about the implementation team?
We are an integrator and can help customers set up the solution.
What was our ROI?
While there may be a potential for ROI, I don’t track it.
What's my experience with pricing, setup cost, and licensing?
I’m not sure about the licensing. I don’t handle this aspect of the product.

Information Security Coordinator at a non-tech company with 5,001-10,000 employees
Enables us to monitor IP locations
Pros and Cons
- "We can monitor IP locations, but we have constraints from each country. It has a replication feature. Licenses can be shared, taking turns with each license."
- "The reporting could be clearer and embedded to include our movement data."
What is our primary use case?
We have many types of service, provided by the company.
What is most valuable?
We can monitor IP locations, but we have constraints from each country. It has a replication feature. Licenses can be shared, taking turns with each license.
What needs improvement?
The reporting could be clearer and embedded to include our movement data. The product could improve the interface by reducing the bookmarking more frequently and some other features. Ideally, it could do with a brand new interface. There is sometimes information overload in the logs. It is sometimes difficult to detect attacks on the firewall because it is hidden amongst many other data. The logs are not always helpful in this regard. I was disappointed in the reporting.
For how long have I used the solution?
We have been using F5 Advanced Web Application Firewall for about one year and the same for Fortinet FortiWeb.
What do I think about the scalability of the solution?
Scalability is fine, and we don't have any complaints so far. It's flexible once you want to expand it, but that includes the license upgrade for additional features.
How are customer service and technical support?
We use a reseller for technical support. Technical support is very good.
Which solution did I use previously and why did I switch?
We have looked at other options, but they have different solutions to the F5 Advanced Web Application Firewall.
How was the initial setup?
Setup and installation are easy.
What about the implementation team?
We use the reseller to implement it from scratch until it is fully deployed. Implementation does not take long.
What's my experience with pricing, setup cost, and licensing?
There are various plans available for Fortinet FortiWeb Cloud WAF as a Service, including a trial version. You are only charged by the total data transferred, and there are hourly charges for the protected web application.
Which other solutions did I evaluate?
We are constantly looking out for features which are not available in the current product. We have set alerts to flag when these features become available.
What other advice do I have?
I would rate this solution as 9 out of 10. They can combine firewall software with other software solutions with this product. It has a good community to see what other ideas for the product are out there.
Which deployment model are you using for this solution?

If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?

What is most valuable?
It is easy to use, and it's also easy to configure.
The most valuable feature is that it is secure.

We usually ask for their support and they provide it to us.
Which solution did I use previously and why did I switch?
Previously, we used BIG-IP and we used Web Application Firewall.
How was the initial setup?
I was not involved in the installation.
What other advice do I have?
I am currently working on a B2C channel, which is more for retail companies.
