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.

Offers Application Protection Against Web Attacks

There is a need for expanded licensing terms and options. There's also a need for improved and more agile customization features. The user needs to be able to manage each policy as required; the functionality needs to empower the user. There should be a complete suite of desktop provider policies available to users. Overall, it needs to be more user-friendly.

Quotes from Members

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

Pros

"The most valuable feature of F5 Advanced WAF is its grand unity of the implementation, where you have the freedom to configure based on how it affects your use case or your organization. With the default setting of implicit deny, you can gradually start defining and deploying the tool to align with your environment, whether it is outdated, recent, or futuristic. This allows you to customize the solution to protect you from threat actors. You have the ability to define what the advanced threat act should do - whether it should alert, deny, or both - and it will deliver based on your configuration. Unlike other online solutions, F5 Advanced WAF provides flexibility to deliver to your unique environment the way you want."
