Application security has protected critical banking services while policy learning minimizes false blocks

F5 Advanced WAF performs well overall, but I have noticed some points that could enhance the solution. Initially, policy tuning could be simpler, as while the learning engine is powerful, initial tuning still requires experienced engineers, which can be challenging for new teams due to the complexity of options and parameters. A more guided and simple tuning workflow would help reduce the learning curve. Additionally, tighter native integration with SIEM or SOAR tools would simplify correlation and investigations for security teams, although log exports are available. Overall, these are not blockers, merely enhancement opportunities, and once tuned, F5 Advanced WAF is very stable and reliable; improving usability, reporting, and onboarding would make it even more effective for larger environments.

Geo-localization and IP reputation help to keep our clients secure and more available

The area that should be improved is licensing. When using an active/passive cluster, we have to pay 70% of the master appliance and license for the passive server that does not work. Since we know that only one server works at a time, we should pay only one license for the appliances and for the support as well. In my opinion, this has to be improved. If possible, the client software should be a web application instead of downloading software for the management. This can avoid login problems when they update or patch.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"It protects and mitigates damage in the network."

"This solution inspects your traffic and based on that, automatically create distinct qualities for you, so you can add this to the policy already created. That's what I like most."

"Provides good protection from attacks."

"The bot defense capability, as well as protection from brute force attacks and OWASP Top Ten, are notable features."

"I appreciate the way F5 Advanced WAF builds policies by configuring a basic policy and queuing it in learning mode."

"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 most valuable features of F5 Advanced WAF are the overall capabilities, there is not a comparable solution on the market."

"The solution isn't too expensive. The license allows you to license what you need and leave out what you don't need."

More F5 Advanced WAF pros

"The three most valuable features that I noticed are the geo-localization of the user, the IP reputation, and the compartmental analysis."

Cons

"Most customers encounter stability issues with the product's Big-IP logs."

"I would like for there to be a cloud-based solution, this would also help to improve scalability."

"The interface is old-looking, it's not modern, which is why it's not always comfortable to use."

"We usually use a third-party tool for logging and reporting. It would be nice if we could do that right on this solution. They have one, but it's not very stable. Logging and reporting effectively would be a big enhancement."

"The administrator's user interface and some of the settings can sometimes be very complicated to understand."

"This solution can be made more user-friendly."

"One area for improvement in the product is its SSO integration, which posed challenges and required significant effort to resolve."

"Scalability could be improved."

More F5 Advanced WAF cons

"The area that should be improved is licensing."

Pricing and Cost Advice

"It's more expensive than other solutions and depending on the modules, there can be additional fees."

"As far as the pricing of F5 Advanced WAF I would rate it a four out of five depending on what features I am looking for. Imperva is more expensive."

"Pricing for this solution is higher than average."

"It is expensive. Its price should be better. Its licensing is on a yearly basis. Its licensing is also based on the model. There are no additional costs."

"The solution is very expensive so should only be used in the right environment."

"Its price is fair. We have done a couple of deals where they were able to give some kind of discount to the customers. The price was initially high for the customers, but after a couple of negotiations, it came within their budget. They were happy with that."

"There are various plans available for Fortinet FortiWeb Cloud WAF as a Service, including a trial version."

"There are different licenses available to use F5 Advanced WAF, such as BT, ASM, and LPM."
