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.

Strong policies and bot defenses have secured critical APIs and have reduced attack noise
From my research regarding the IAM space that Imperva Application Security Platform is trying to look into, I believe they still need to do a lot of modeling and modification to make sure that also helps. There are several competitors in the IAM space, so Imperva would do well if they can do some basic modeling and modifications from my own personal research and my own experience in the IAM space. Alternatively, they could actually just focus on trying to be stronger in the web application space and the database activity monitoring space.The main reason it is not a perfect ten is regarding support. At times, having to reach the support team takes eight hours to ten hours maximum. There are times when clients could have urgent issues to attend to. The support team could do more by having a faster response rate.

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."
"It's pretty convenient and pretty easy to set up and run. And then kind of for static content, it also offers caching."
"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."
"For us, the key feature of Cloudflare is DDoS protection and IP hiding, especially since we are a crypto company."
"I'm highly satisfied. It's remarkably user-friendly, enabling me to quickly identify issues, and deploy solutions, and it offers the necessary features."
"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."
"It protects web applications efficiently."
"The most valuable part of the solution for us overall is exactly that it is a Software-as-a-Service product."
"The configurability of the tools and the ease of operation to be the most valuable feature of Imperva."
"The solution is stable."
"The availability of our sites, thanks to the load balance functionality, has improved, and it enables the site to be available all the time, despite people trying to attack it."
"Hands down, the WAF is the most valuable feature; being able to identify, block, whitelist or blacklist as needed, are all valuable."
"Imperva Application Security Platform has positively impacted my organization by providing strong protection for web applications, as many big companies in the UK use Imperva WAF as an essential protection layer, illustrating its effectiveness."
"Customer Support has been the biggest help in dire situations."
"Provides Anti-DDoS protection, as well as other protections like SQL injection, Cross-Site Scripting, and antiscanner. These types of protection are valuable to the business due to the daily attacks on our portals, and that often cannot be seen without a tool like this."
"The website itself is our first priority and we have seen improvements in that area -- it's faster."
"I would give Radware Kubernetes WAF a rating of 10 out of 10."
 

Cons

"It would be ideal if the solution offered better log integration and more integration with different platforms."
"The blocked logs are difficult to read at times."
"The learning curve was steep initially."
"Cloudflare Web Application Firewall should improve visibility for a customer."
"They have some limitations with third-party integrations."
"They have some limitations with third-party integrations."
"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."
"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 support for the on-premises version needs improvement."
"Imperva now offers add-ons to add functionality, but I would like to see these included in the product, even if it would cost more."
"We need an improvement in the support. We need a lot of turnarounds."
"We looked at CloudFlare. We tried it but it didn’t work that well."
"The reporting is missing some features, such as: only two export formats, and the time period does not include the last day, week, year."
"It would be nice to have more security control over mobile applications so I would suggest adding more mobile security features. It would also be beneficial to see improvements in regards to interface bandwidth performance, CPU time, and RAM size. Learning capability of the device is quite weak."
"Our support is currently coming from the US, and it is not very good."
"Imperva Web Application Firewall could improve the console by making it easier to use."
"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 annual licensing fee is $10,000 USD."
"It starts at $20 and can easily go up to $200 monthly"
"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."
"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."
"We pay $210 per month for CloudFlare WAF."
"It is not too pricey."
"It is not expensive compared to the other similar solutions in this category."
"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."
"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."
"There is a license or subscription renewal that our customers pay."
"Varies depending on the needs of the customer."
"Pricing could be more competitive."
"The tool's pricing is good."
"Imperva Web Application Firewall price is higher compared to other solutions. However, everything is included in the price."
