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 stability of Cloudflare Web Application Firewall deserves a perfect 10 out of 10."
"The security features are valuable. The particular feature we use is called OWASP."
"In general, it's a very good product: the solution is very stable, the performance is great, the product offers very good scalability, the pricing is very reasonable, the installation is very straightforward and quite simple, and technical support has a very fast response time and is helpful."
"The most valuable part of the solution for us overall is exactly that it is a Software-as-a-Service product."
"The setup process is very simple for me."
"For us, the key feature of Cloudflare is DDoS protection and IP hiding, especially since we are a crypto company."
"The product has improved our security posture by blocking bad actors."
"The solution protects our application, which runs on the HTTP protocol, from DDoS attacks."
"IncapRules is one of the most valuable features, as you can create your own security and access control rules on top of your security policy. Using IncapRules we were able to easily block Layer 7 DDoS attacks several times."
"The solution has a very good interface."
"The solution is scalable."
"I find the configurability of the tools and the ease of operation to be the most valuable feature of Imperva."
"The features that are most valuable are the protection against denial-of-service attacks and all kinds of other internet attacks."
"The website itself is our first priority and we have seen improvements in that area -- it's faster."
"Imperva is one of the best, if not the best, and almost every feature in Imperva Application Security Platform works really fine and addresses what enterprises are battling, shaping the security culture of the digital world."
"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."
"I would give Radware Kubernetes WAF a rating of 10 out of 10."
 

Cons

"I have experienced some difficulties with Cloudflare's support as a customer based in India."
"The rate limiting functionality could be enhanced, as we find it somewhat limited."
"We don't even use Cloudflare Bot Management because it's too expensive; you need to pay per request, and it's much cheaper to get one or two additional machines."
"They have some limitations with third-party integrations."
"Their documentation could be better. They don't have documentation that explains everything well."
"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."
"They need to improve their support because getting a response for basic requests took around 48 hours, which is too long."
"We have noticed some latency when the call goes through the firewall. That could be improved."
"Imperva Web Application Firewall can improve by providing better features, such as improved prevention of zero-day attacks. Additionally, it should include a VR meta-analysis."
"Learning capability of the device is quite weak."
"We faced issues regarding compliance with client procedures. The client had strict compliance rules, and Imperva needed to be on a VM, while the client required containerization, causing a conflict. They went with Imperva for the on-premise version but shelved the cloud project due to too many blockers."
"It would be useful if the solution used more intelligence in attack protection."
"Their customer service sometimes has different responses for similar requests. We sometimes need to explain the issue many times before they understand."
"Incapsula: Allow easier scripting of firewall rules."
"I would say that technical support is average."
"One improvement I would like to see in Imperva Application Security Platform is the ability to fail over to different sites for my same application."
"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."
"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 solution is expensive."
"It starts at $20 and can easily go up to $200 monthly"
"The annual licensing fee is $10,000 USD."
"The tool's pricing is good."
"Imperva Web Application Firewall is expensive."
"Everybody complains about the price of this solution."
"The cost is on par with other solutions such as Cloudflare and Akamai."
"Varies depending on the needs of the customer."
"Licensing can range from one to twenty thousand dollars annually. Additionally, some features, including software support, require an annual subscription as well."
"It's an excellent product, but it can be very costly."
"Pricing could be more competitive."
