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."
"Cloudflare WAF provides protection through rules and functionalities like Cloudflare's SDRAP."
"This solution does a good job of preventing web application attacks, SQL injections, and cross-site scripting attacks."
"The security features are valuable. The particular feature we use is called OWASP."
"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."
"The product has a valuable security control functionality."
"Cloudflare is cheaper compared to Azure WAF, which I have considered before."
"We like that there's load balancing, firewall capabilities, DDoS protection, et cetera, all covered by Cloudflare."
"Deployment is simple and very fast."
"The most valuable feature of Imperva DDoS is to make our website available for our customers' requests 24 hours a day."
"It is easy to manage and expand."
"Well, just by using the security rules to block all secured areas by IP minimized the chance of sensitive data leaking outside."
"The solution's most valuable aspect is that it is easy to configure."
"The setup of Imperva DDoS was easy."
"One good thing about Imperva Web Application Firewall is it can be on the cloud and also it can be on-premise."
"I would recommend this solution to others; it has been working fine for us, and it has all the features that we need."
"I would give Radware Kubernetes WAF a rating of 10 out of 10."
 

Cons

"Its stability could be better."
"They have some limitations with third-party integrations."
"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 user interface is very simple and straightforward, but users need knowledge about DNS to accomplish tasks."
"If they add logs history within the Cloudflare offering, that would be a great benefit."
"Cloudflare Web Application Firewall should include port forwarding features."
"Support can be challenging at times."
"The accuracy of the Cloudflare Web Application Firewall could be improved by reducing the number of false-negative alerts."
"It's quite expensive."
"The product's customization capabilities are a bit problematic, requiring support cases for backend modifications."
"It would be better if we were able to manage and apply changes to multiple websites/web applications, and search WAF logs for multiple websites, via the Incapsula dashboard."
"Its price could be improved. It is quite expensive."
"Everybody complains about the price of this solution."
"I don't really use it and therefore can't speak to areas of improvement."
"Imperva always needs to adjust to new versions of cyber attacks, it needs to be faster, improve the resiliency of the software of the solution."
"Incapsula services also provides load balancing services for their service IP address environment. So far, with monitoring their services, the IP address was only changed once."
"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 Web Application Firewall is more affordable than other solutions."
"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 pricing model is very straightforward compared to the competition. You just pay per month for the product and usage."
"It starts at $20 and can easily go up to $200 monthly"
"The annual licensing fee is $10,000 USD."
"Cloudflare offers different types of subscriptions for businesses, enterprises, and personal users, and the pricing is negotiable."
"The solution's pricing option needs to be more transparent for enterprise clients."
"It is expensive."
"There are some licenses that you have to buy to use some features. Its price could be better. Price is always important because, at the end of the day, customers have a budget. If you can meet the budget, you can sell, and if you don't, you cannot sell."
"I rate the product price a four on a scale of one to ten, where one is a low price, and ten is a high price."
"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."
"There are a couple of different licensing models."
"Imperva Web Application Firewall is expensive."
"It is a very affordable solution."
"Imperva charges us based on bandwidth, which is better than other vendors that charge us according to data transfer."
