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.

Quotes from Members

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

Pros

"Cloudflare is cheaper compared to Azure WAF, which I have considered before."

"The integration of Cloudflare with Cloud Suite is its most valuable feature."

"Cloudflare has positively impacted my organization by making it easier for me to handle and set up DNS for multiple clients; I can easily go in and access their accounts, make changes they need, and it's a one-stop shop."

"Cloudflare WAF provides protection through rules and functionalities like Cloudflare's SDRAP."

"The setup process is very simple for me."

"It's pretty convenient and pretty easy to set up and run. And then kind of for static content, it also offers caching."

"Someone with a basic understanding of networking and security will be able to implement the firewall's basic features within 15 minutes."

"The initial setup process is simple."

More Cloudflare Web Application Firewall pros

"It's a fairly easy-to-use and user-friendly tool. My administrators and team also like its ability to customize the rules per the requirements."

"It also has antivirus and DDoS mitigation capabilities. We have enabled these features."

"The most valuable features of the F5 Advanced WAF are the enhanced ASM and the performance. Additionally, the usability and effectiveness are very good."

"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."

"The product is used to secure web applications and has the ability to use API templates and bot protection features, such as blocking requests or presenting CAPTCHA pages to end users."

"F5 Advanced WAF secures our connectivity and combines both the main functions of WAF (balancing and web application security)."

"The most valuable features of F5 Advanced WAF are the easy identification of events and customization. We can pinpoint our settings."

"It ensures compliance with security standards by providing features like PCI DSS checks."

More F5 Advanced WAF pros

"Since we are using this tool for protection purposes we really appreciate the hybrid security abilities; the main idea here is that we powerful protection our application needs."

Cons

"Cloudflare Web Application Firewall should include port forwarding features."

"The reporting could be more granular."

"It would be ideal if the solution offered better log integration and more integration with different platforms."

"There could be an option to duplicate the cluster to maintain the consistency of rules."

"Their documentation could be better. They don't have documentation that explains everything well. They have documentation for everything you're looking for, but they lack a single piece of documentation to tie everything together. As a new user or beginner, it took us a little bit of time to figure out how to put all these things in place."

"The platform's control features related to real-time authentication and response time need improvement."

"They need to improve their support because getting a response for basic requests took around 48 hours, which is too long."

"Support can be challenging at times."

More Cloudflare Web Application Firewall cons

"It's a powerful tool yet can be complex for new users."

"Compatibility with multiple cloud environments needs improvement. Both stability and scalability need to be improved."

"F5 Advanced WAF could improve resource usage, it is CPU intensive. Additionally, adding automated remediation would be a benefit. For example, an easy button alerts us of the events that are occurring, and what we want to do at the time. An automated approach where somebody could be alerted very quickly. Instead of going and reconfiguring everything, an automated approach is what I'm looking at."

"The deployment side is quite complex."

"There is a learning curve that extends the time of implementation."

"The delay times on firmware patches and software updates could be better and improved."

"The BIG-IQ is supposed to centralize the management for all of the boxes but it's not very effective."

"F5 Advanced WAF could improve on its funding for WAF features. There is a need to be more advanced WAF features."

More F5 Advanced WAF cons

"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."

Pricing and Cost Advice

"The solution's pricing option needs to be more transparent for enterprise clients."

"We pay $210 per month for CloudFlare WAF."

"It is not too pricey."

"It starts at $20 and can easily go up to $200 monthly"
