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.

"It is a SaaS solution unlike much of the competition."

More Cloudflare Web Application Firewall pros

"The technical support is excellent."

"Initially, there were over 1,500 vulnerabilities, but we managed to fix almost all of them within three months, leaving only two low severity issues outstanding."

"This product is a reliable defense from malicious attacks on a network environment."

"Imperva makes it easier for us to put everything in code; we use Terraform to deploy our infrastructure."

"The most valuable aspect of it is that it blocks all types of attacks."

"The stability of the product is good since I haven't had any problems with the solution."

"The Imperva Web Application Firewall feature I have found the most valuable is the ease of deployment."

"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."

More Imperva Application Security Platform pros

"I would give Radware Kubernetes WAF a rating of 10 out of 10."

Cons

"The user interface is very simple and straightforward, but users need knowledge about DNS to accomplish tasks."

"They need to improve their support because getting a response for basic requests took around 48 hours, which is too long."

"The notification part could be improved. It's very much connected to Web Application Firewall, rate-limiting, and DDoS protection."

"The learning curve was steep initially."

"They have some limitations with third-party integrations."

"The blocked logs are difficult to read at times."

"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."

More Cloudflare Web Application Firewall cons

"The interface seems a bit outdated and simplistic."

"There's always room for improvement. Occasionally, there might be false-positive alerts."

"The support for the on-premises version needs improvement."

"I would say that technical support is average."

"It needs to be improved every time there are new attacks."

"The API is lackluster but especially for customers."

"The cost could be lower; our end clients need to have a high budget to purchase this solution."

"Users would benefit from better documentation. There is official documentation, but sometimes we need more detail. We have some use cases that are not so run of the mill. It would be great if there was a knowledge base that we could go to for more answers."

More Imperva Application Security Platform cons

"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."

"The solution's pricing option needs to be more transparent for enterprise clients."

"Cloudflare Web Application Firewall is more affordable than other solutions."

"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."

"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."

More Cloudflare Web Application Firewall pricing and cost advice

"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."

"For enterprise contracts you will be in touch with a dedicated account manager who will guide you regarding licensing."

"There is a license for this solution and we purchase the license annually with no additional fees."

"Although the pricing can be a little high, it is worth the protection and security that it offers."

"The data packages are higher than our needs so we end up paying for data that we don't use."

"The cost is on par with other solutions such as Cloudflare and Akamai."

"It's an excellent product, but it can be very costly."

"We have an issue with Imperva Incapsula in the Iraqi market because of the high price."
