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

"There is a huge signature repository"
"This is a good product; it's reliable and scales well."
"The product has a valuable security control functionality."
"The solution protects our application, which runs on the HTTP protocol, from DDoS attacks."
"The most valuable part of the solution for us overall is exactly that it is a Software-as-a-Service product."
"I'm highly satisfied. It's remarkably user-friendly, enabling me to quickly identify issues, and deploy solutions, and it offers the necessary features."
"The security features are valuable. The particular feature we use is called OWASP."
"The stability of Cloudflare Web Application Firewall deserves a perfect 10 out of 10."
"After moving to Imperva Application Security Platform, these attacks have been prevented significantly, and the attacks on the initial level have been considerably reduced."
"If you are using the appliance as opposed to the virtual deployment, it can stand as the network layer-two and provide real transparency."
"The Imperva Web Application Firewall feature I have found the most valuable is the ease of deployment."
"Based on my experience, and what I know this product can do, I would never recommend another solution."
"Data masking is the most valuable feature of this solution."
"In my opinion, Imperva Incapsula is not expensive compared to the other similar solutions in this category."
"Scalability is pretty easy on the base platform. You just add another, and you're ready to go."
"Final words : I was pretty much convinced by the Incapsula CDN, Overall it worked well without any glitches or breaking down the theme or stylesheet of my blog."
"I would give Radware Kubernetes WAF a rating of 10 out of 10."
 

Cons

"The accuracy of the Cloudflare Web Application Firewall could be improved by reducing the number of false-negative alerts."
"The dashboard could be more user-friendly."
"The reporting could be improved if it were more granular."
"They have some limitations with third-party integrations."
"The user interface is very simple and straightforward, but users need knowledge about DNS to accomplish tasks."
"The product can improve by having more multitenancy capability, which is currently not available."
"It would be ideal if the solution offered better log integration and more integration with different platforms."
"The rate limiting functionality could be enhanced, as we find it somewhat limited."
"Improve reporting interface and filtering."
"There are times that we experienced downtime or crashes with Imperva Application Security Platform; there were times that it crashed, it did not load, and we had to wait until it was fine."
"Incapsula: Allow easier scripting of firewall rules."
"Some of the features should be included in the next release is a file integrating monitoring tool. This feature should be improved."
"I would suggest that Imperva Application Security Platform should include new features combined with AI."
"I loved the approach of the cloud. The cloud has a lot of new features, like advanced web protection and DDoS protection. If those could also be on-boarded onto the on-prem versions, that would be ideal. They need to pay attention to both deployment options and not just favor one."
"Some maintenance must be performed by our IT team."
"As such, I have not seen a return on investment."
"If Radware provides a separate web service like those offered by vendors such as F5 and Imperva, that would be better."
 

Pricing and Cost Advice

"Cloudflare offers different types of subscriptions for businesses, enterprises, and personal users, and the pricing is negotiable."
"It starts at $20 and can easily go up to $200 monthly"
"What's my experience with pricing, setup cost, and licensing? I believe the pricing is not the best, but it's reasonable and acceptable. We also use the McAfee system in parallel. In terms of pricing, its okay - not great, but not bad either. It falls in the middle, which is acceptable. In terms of support licensing, last time, we were searching for a solution, and we considered products from resellers rather than directly from the cloud provider. However, the pricing we encountered was exceptionally high. As a result, we are inclined to select support from the reseller."
"Cloudflare Web Application Firewall is more affordable than other solutions."
"The solution is expensive."
"The solution's pricing option needs to be more transparent for enterprise clients."
"It is not too pricey."
"The annual licensing fee is $10,000 USD."
"There is a license or subscription renewal that our customers pay."
"Imperva Web Application Firewall's pricing is expensive."
"​Although the pricing can be a little high, it is worth the protection and security that it offers.​"
"Make sure you understand the way that Imperva charges. It's very affordable. However, I would like to see a package with the Virtual Patching included. You get to do patching separately."
"The cost is somewhere around $10,000 a site. For every site, you pay individually. For every DNS entry, you have you pay."
"The price of this solution is a little bit high compared to competitors."
"The tool's pricing is good."
"It's an excellent product, but it can be very costly."
