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 initial setup process is simple."
"The product has a valuable security control functionality."
"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."
"It is configurable via API."
"The product has improved our security posture by blocking bad actors."
"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 stability of Cloudflare Web Application Firewall deserves a perfect 10 out of 10."
"For us, the key feature of Cloudflare is DDoS protection and IP hiding, especially since we are a crypto company."
"There is a quick switch between any of the the nodes if something goes wrong, where there's a there's an attack against a specific area. The security setup is reasonably easy. It's not a problem to do setups and rules and integrations. And, yeah, just the the back end team is also very willing to insist if there's questions that that we cannot answer or with these questions that we do have"
"On the site security, I can see which countries have incidents, whether it was a robot attack, a real human user, or non-human user."
"Basic setup is simple but, as with any caching/WAF setup, there are tricks you need to learn, but it works really nice out of the box!"
"My advice to anyone considering Imperva Web Application Firewall is that they can safely go to this environment without having a second thought."
"The solution is stable."
"Learning mode and custom policies are helpful features."
"It is a stable solution."
"The solution can be configured in just a couple of minutes, ensures 99.7% availability for my applications, provides an additional layer of security for web and mobile applications, protects my environment, and helps maintain my reputation in the market."
"I would give Radware Kubernetes WAF a rating of 10 out of 10."
 

Cons

"Support can be challenging at times."
"Their documentation could be better. They don't have documentation that explains everything well."
"I have experienced some difficulties with Cloudflare's support as a customer based in India."
"The user interface is very simple and straightforward, but users need knowledge about DNS to accomplish tasks."
"The notification part could be improved. It's very much connected to Web Application Firewall, rate-limiting, and DDoS protection."
"We have noticed some latency when the call goes through the firewall. That could be improved."
"The solution's learning curve can still be further reduced"
"Cloudflare should update the version of the ModSecurity core rule set that they run on."
"We faced challenges with high costs, as the customer perceived pricing for gateways to be excessive, but we handled multiple billing instances with sophisticated setups."
"The reporting is missing some features, such as: only two export formats, and the time period does not include the last day, week, year."
"The tool needs to include artificial intelligence and machine learning. It also needs to improve profiling."
"Learning capability of the device is quite weak."
"Customer Service: Average to poor. Technical Support: Average to poor."
"They guarantee to fix your problem within 15 minutes, but they don’t always keep their word."
"They can provide an option to create a report, automatically import the entire report, and create rules again."
"It would be nice to have a mobile app as a dashboard interface instead of the web administration, but the service is really great."
"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

"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."
"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."
"It starts at $20 and can easily go up to $200 monthly"
"Cloudflare Web Application Firewall is more affordable than other solutions."
"The annual licensing fee is $10,000 USD."
"We pay $210 per month for CloudFlare WAF."
"Imperva Web Application Firewall is expensive."
"There is a license or subscription renewal that our customers pay."
"The price of this solution is a little bit high compared to competitors."
"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."
"The data packages are higher than our needs so we end up paying for data that we don't use."
"Pricing could be more competitive."
"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."
"For enterprise contracts you will be in touch with a dedicated account manager who will guide you regarding licensing."
