After implementing F5 Advanced WAF, nearly 99.9% of requests are legitimate due to the granularity and response verification by attack patterns and request blocking.

Overall, F5 Advanced WAF is a strong, dependable enterprise solution that works best when seen as a long-term security platform rather than a quick add-on; once properly designed, sized, and tuned, it runs quietly in the background and effectively does its job without constant attention.

The level of configurability that I get with F5 Advanced WAF solution is immense, and I have to be a bit aware of how it works and all of its features, but at the end of the day, it is all about the administration expertise that I will require to have and use it to my liking based on the kind of services that I have onboarded on my solution itself.

Improvements could be made regarding the log information from the backend CLI; if a request gets blocked on the TCP layer, there should be traces or data to verify which source generated these requests, including the source and port information for initiation.

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.

On the features I wish existed, Big-IP Advanced WAF is primarily an on-premises solution and in that solution, there are not enough features that need to be there to protect API-based applications.
