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

"The Cloudflare Web Application Firewall's most valuable feature is its ease of configuration."
"Caching is the most valuable feature of Cloudflare Web Application Firewall."
"Very glad the WAF rulesets works out of box, and requires very little tuning or maintenance."
"There is a huge signature repository"
"The stability of Cloudflare Web Application Firewall deserves a perfect 10 out of 10."
"It's pretty convenient and pretty easy to set up and run. And then kind of for static content, it also offers caching."
"We extensively use the solution every day. The solution is very stable; we haven’t seen any glitches."
"It is a SaaS solution unlike much of the competition."
"DDoS protection and WAF are the most valuable features. It is easy to deploy a service. It is easy and quick to deploy to a new website."
"On the real time, you can see live traffic, which is flowing into our website."
"Since implementing Imperva Application Security Platform WAF, as mentioned earlier, only legitimate traffic reaches the server and the router to request what they need, and of course, the response is given."
"Imperva WAF's strongest features are the detection of web application threats and vulnerabilities in the source code."
"The solution is very good at intercepting traffic before it gets to our data centers."
"The dashboard is good and user-friendly."
"I would say compare it to other solutions in the marketplace feature by feature and see how Incapsula reporting and analytics dashboards compare and bot control compares – their solution for bot control is pretty good – and check those features with other enterprise level solutions, you get a lot for your money."
"The features that are most valuable are the protection against denial-of-service attacks and all kinds of other internet attacks."
"I would give Radware Kubernetes WAF a rating of 10 out of 10."
 

Cons

"We have noticed some latency when the call goes through the firewall. That could be improved."
"The accuracy of the Cloudflare Web Application Firewall could be improved by reducing the number of false-negative alerts."
"A key challenge arises when dealing with numerous integrations with HVAC systems. Depending on the specifics, there might be some configuration mismatches, which necessitate specific support."
"Support can be challenging at times."
"The rate limiting functionality could be enhanced, as we find it somewhat limited."
"Its stability could be better."
"The dashboard could be more user-friendly."
"The solution's learning curve can still be further reduced"
"Their portal is very limited and needs improvement."
"It needs to be improved every time there are new attacks."
"Delivery services and information security."
"I am looking for more data enrichment. We should have the ability to add our own custom data to the system, to the live traffic."
"I would like the solution to improve its support response time."
"Sometimes, support tickets don't get addressed quickly."
"I am not sure if this application has a policy where you can create your custom policy and run it as our firewall. We should have some ability to also create some custom policy, then run it as a firewall."
"It's a complicated tool to keep."
"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

"The solution's pricing option needs to be more transparent for enterprise clients."
"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 annual licensing fee is $10,000 USD."
"The pricing model is very straightforward compared to the competition. You just pay per month for the product and usage."
"It is not too pricey."
"We pay $210 per month for CloudFlare WAF."
"It starts at $20 and can easily go up to $200 monthly"
"Cloudflare offers different types of subscriptions for businesses, enterprises, and personal users, and the pricing is negotiable."
"The price of this solution is a little bit high compared to competitors."
"It is not expensive compared to the other similar solutions in this category."
"The tool 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."
"The cost is on par with other solutions such as Cloudflare and Akamai."
"Pricing could be more competitive."
"The price is high compared to other solutions like FortiWeb."
"There is a license for this solution and we purchase the license annually with no additional fees."
