Featured Reviews

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

Cyber Security Consultant at ProTechmanize

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 better visibility into user sessions compared to other solutions

Improvements are needed to address the issue of machines becoming unregistered, ensuring stability for end users. Troubleshooting with Citrix support can be challenging, so clearer diagnostics would be beneficial. As for global server load balancing, it works well on-premises, depending on user volume and service stability. Overall, it's satisfactory for us.
