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.

Cons

"Cloudflare Web Application Firewall should improve visibility for a customer."
"We have noticed some latency when the call goes through the firewall. That could be improved."
"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 blocked logs are difficult to read at times."
"If they add logs history within the Cloudflare offering, that would be a great benefit."

"Incapsula: Allow easier scripting of firewall rules."
"Analytics in the area of risk need to be improved to supply more information to the users for creating better environments."
"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

"It is not too pricey."
"We pay $210 per month for CloudFlare WAF."
"Cloudflare Web Application Firewall is more affordable than other solutions."
"Cloudflare offers different types of subscriptions for businesses, enterprises, and personal users, and the pricing is negotiable."
"The annual licensing fee is $10,000 USD."
"The solution is expensive."
"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."
"The solution's pricing option needs to be more transparent for enterprise clients."
"There is a license or subscription renewal that our customers pay."
"It's an excellent product, but it can be very costly."
"The cost of this solution depends on the platform."
"On a scale from one to ten, where one is cheap and ten is expensive, I rate the solution's pricing a five out of ten."
"It is very costly, but the return on investment is very high. Its cost was around $70,000, and we got it back in just six months."
"The solution's pricing is an issue."
"Varies depending on the needs of the customer."
"The tool is expensive."
