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 protection has improved and reporting and dashboards still need refinement
I believe Imperva Application Security Platform should have a more interactive wizard. While the dashboard is good, it could be more eye-catching. Based on my perspective, I recommend modifying the dashboards, especially the main dashboard where I can see the traffic hit count, alerts, and other latest information. In terms of reporting, I find it challenging to create reports; in my earlier days, it was difficult. Over time, I have learned how to create reports, but it should be easier to do so. I have used other tools such as firewalls or SolarWinds, where creating a report is straightforward and does not take much time, unlike in Imperva, where I have to add many elements. Modifications in the integration aspects would also be beneficial.

Quotes from Members

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

Pros

"It's pretty convenient and pretty easy to set up and run. And then kind of for static content, it also offers caching."
"The impact of Cloudflare Web Application Firewall's integration with existing web technologies on our site's performance and security measures is quite great, actually."
"The stability of Cloudflare Web Application Firewall deserves a perfect 10 out of 10."
"The security features are valuable. The particular feature we use is called OWASP."
"Technical support has a very fast response time and they are helpful."
"It is configurable via API."
"The integration of Cloudflare with Cloud Suite is its most valuable feature."
"The rate limiting features and customizations in terms of URL match and applying policies are valuable to me."
"Great product, it will not let you down!"
"On the real time, you can see live traffic, which is flowing into our website."
"The solution is very good at intercepting traffic before it gets to our data centers."
"Bad-IP blocking and signature-based blocking for web application security."
"I am impressed with the product's scalability, availability, easy management, and security. We were able to integrate the product with Azure and Sentinel."
"One good thing about Imperva Web Application Firewall is it can be on the cloud and also it can be on-premise."

"I like the user-friendly interface."
"The product’s most valuable is WAF. The authentication feature helps us protect WordPress sites."
 

Cons

"The notification part could be improved. It's very much connected to Web Application Firewall, rate-limiting, and DDoS protection."
"Its stability could be better."
"We don't even use Cloudflare Bot Management because it's too expensive; you need to pay per request, and it's much cheaper to get one or two additional machines."
"Cloudflare Web Application Firewall should include port forwarding features."
"Cloudflare should update the version of the ModSecurity core rule set that they run on."
"They have some limitations with third-party integrations."
"The dashboard could be more user-friendly."
"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."
"They can provide an option to create a report, automatically import the entire report, and create rules again."
"We rate technical support as really bad."
"Users would benefit from better documentation. There is official documentation, but sometimes we need more detail."
"The API is lackluster but especially for customers."
"Communication declined a bit as they got bigger – 7/10."
"The Imperva Web Application Firewall automations are good, but there is still room for improvement with them."
"The rules surrounding the making of web applications could be improved."
"Certificate management could be improved."
"The product’s performance for caching feature needs improvement."
