For me, the primary use case is to secure web applications from external threats, including cross-site scripting, SQL injection attacks, file inclusion vulnerabilities, and many more. The tool has simplified protection against web applications and recent threats that might be visible. If your applications are vulnerable, it gets protected by F5.

iRules has the ability to prevent the end-user and infrastructure from external threats
Pros and Cons
- "iRules are quite appealing when it comes to F5."
What is our primary use case?
What is most valuable?
It is a very flexible solution. iRules is quite appealing when it comes to F5, and they apply it throughout their solution. BIG-IP is a known platform, and it is a part of F5 now. Application delivery or web application firewalls, F5 understands these terms and then suggests better data policies. But you have to do the work on your application's performance first. You have to look in the logs and understand the total attack you should prevent when we put it in the circuit protection mode, which works perfectly well.
iRules truly excites me because it has the ability to prevent the end-user and infrastructure from external threats.
Even if the F5’s default signatures and the default behavior are unable to help you, you can customize iRules to reach the objectives.
What needs improvement?
I don't like the management control of F5.
Moreover, if you are not an expert, it would be really difficult to set it up.
For how long have I used the solution?
I have been using the product for fifteen years or more.

We are distributors in Vietnam. We consult for our customers and I am a Product Manager. We use F5 Advanced WAF as a firewall for our website applications and the websites of our customers.
What is most valuable?
The most valuable features of F5 Advanced WAF are the security features and the protection.
In the future, I would like to see F5 include AI in the hardware of F5 Advanced WAF.
What needs improvement?
F5 Advanced needs to improve its bot protection. The solution needs to have machine learning to learn the behavior of the customer to recognize the human versus the bot. This is a difficult feature to explain to our customers. I would like documentation about the bot feature to make it easier for the customer to understand.

Expandable with helpful support and great threat intelligence functionality
Pros and Cons
- "The solution is stable."
- "The deployment side is quite complex."
What is our primary use case?
It's considered one of the modules for the LTM box. It's all modules for the LTM box.
It is actually to protect the customer web application which is published on the internet. It's actually to protect that, and nowadays, we also have this threat intelligence. You will link to the F5 centra, the depository of the threat intelligence database. We always have the latest update on the common threat that is happening currently. You will notify the customer if there's an issue.
What is most valuable?
The threat intelligence function is great. Nowadays, there is more awareness on the security side. They'd have a real-time update from F5. It provides peace of mind on the security side for the customer.
It is an add-on module to protect the web application.
The solution can scale with planning.
The solution is stable.
Support is helpful.
What needs improvement?
The deployment side is quite complex. We'd like them to simplify the implementation process. I'm not sure whether they can do that, however, they have to be very detailed on configurations, and sharing of the policy. Anybody that configures this box, the WAF, they have to have knowledge of the application and some of the security portions there as well.
For how long have I used the solution?
We've had the solution since last year. We have deployed it to a customer.
What do I think about the stability of the solution?
It is stable. Actually, it evolved from ASM, what they call the Application Security Manager, and now they name it Advanced WAF. It's been around for a while. There are no bugs or glitches. It doesn't crash or freeze.
What do I think about the scalability of the solution?
We'll size up based on the customer requirement with some buffer, maybe 20% to 30% for the future extension. There is also some consideration on the capacity planning and the size of the box. You can scale. You just need to plan ahead.
In terms of users, with Advanced WAF, normally their role is more related to the security side.
We just implemented the solution recently and we'll have to wait another three or four years before we change or upgrade the solution.
How are customer service and support?
I've dealt with technical support. We're quite satisfied with them. They're good.
How would you rate customer service and support?
Positive
Which solution did I use previously and why did I switch?
F5 WAF is a web application, in the firewall domain, they have been in the market for a very long time. They know the requirements and the market trends very well. This is the reason why we normally chose F5.
How was the initial setup?
The solution is pretty difficult to set up. You really have to have a grasp o the product to configure it correctly.
The setup takes approximately two months. It's quite a long time. If the application is not ready, then the dependency will be on the application side. Therefore, the cycle is quite long. It depends on the application readiness.
We just need one to two people to handle deployment and maintenance.
What's my experience with pricing, setup cost, and licensing?
The licensing is charged yearly. It's considered expensive, however, there are more expensive WAFs on the market - like Imperva. F5 is second after Imperva in terms of cost. L1 to L3 support is included in the cost.
I'd rate the price of the solution at a four out of five in terms of how expensive it is.
Which other solutions did I evaluate?
We tend to stay with F5, however, we will look at pricing and try to negotiate based on that. We'd like to get a discount and look at the market to see the costs.
What other advice do I have?
I'd advise that new users need to know the requirement expectations, and then the criticality of the application that they're going to let the user use. Sometimes the application is public to the internet for a public user to log into and query the database. In that case, we're exposed to all kinds of external parties. So if you put something that is cheap in place, something that is not able to do the protection properly, then it will be a very big risk to the company.
I'd rate the solution ten out of ten. Our clients have been very happy with it.
Which deployment model are you using for this solution?

Gives the ability to play around with the ciphers and has a immediate display of the support IDs when a real blockage occurs
Pros and Cons
- "My favorite feature of F5 is the ability to play around with the ciphers. I also like the ability to have an immediate display of the support IDs when a real blockage occurs. The protection offered is great."
- "The reporting portion of F5 Advance WAF is not great. They need to work out something better, as it is very basic. You only see the top IPs, I think there is more they can offer."
What is our primary use case?
We host public-facing web applications or APIs. There are web applications that are owned by the company that is exposed to the outside. The internal infrastructure is within the premise. We use F5 to protect them. It's an HA model, and we have two sites.
How has it helped my organization?
We need to have an extra layer of protection. We were previously exposed to the public API. The deployment and the rate of deploying web-based applications had increased. After we introduced the web application firewall, it increased our ability to expose more of the services to the public.
What is most valuable?
My favorite feature of F5 is the ability to play around with the ciphers. I also like the ability to have an immediate display of the support IDs when a real blockage occurs. The protection offered is great.
