Advanced security reporting has protected high-traffic betting platforms from constant attacks
I don't see room for improvement to Cloudflare Web Application Firewall. One thing I don't know much about because we have a dedicated IT team for that, and I'm not involved with Cloudflare much anymore. But if I were to compare them to F5, I would like to see more features that F5 offers. F5 has an option to bring the whole infrastructure, the whole WAF and all their packages, Bot Management, and everything else on your infrastructure. You need to install certain services from their side, and then you can choose if you would like requests to hit your servers immediately or if requests need to be proxied through F5 backbone. That would be a nice addition because we have 90% of the traffic as legit traffic coming from whitelisted servers. If it comes from whitelisted servers, I don't need to go every request through the backbone; I could easily just IP whitelist everything. Then I could maybe have Bot Management on my infrastructure that drastically reduces the price of Cloudflare. I would like to see Push CDN more improved in the next release of Cloudflare Web Application Firewall. And maybe something similar to Pushpin that Fastly has, which is an option where you can push messages that then can be scaled globally over the network. From our perspective, if we have a listener that listens for stock updates, I would just need to have one processor that pushes those updates to the Cloudflare API, and then Cloudflare would broadcast that message to all listeners. Cloudflare will check the order of the message, and if you, as a customer, are not connected or have some kind of network issue, when you reconnect, you will receive the latest state and missing updates.

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.
