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.

For example, if a DDoS attack is happening, it automatically recognizes the attack and prevents it accordingly. Radware Kubernetes WAF provides automation that is effective in dealing with security threats.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Someone with a basic understanding of networking and security will be able to implement the firewall's basic features within 15 minutes."
"There is a huge signature repository"
"The most valuable part of the solution for us overall is exactly that it is a Software-as-a-Service product."
"Cloudflare WAF provides protection through rules and functionalities like Cloudflare's SDRAP."
"We extensively use the solution every day. The solution is very stable; we haven’t seen any glitches."
"It's pretty convenient and pretty easy to set up and run. And then kind of for static content, it also offers caching."
"Caching is the most valuable feature of Cloudflare Web Application Firewall."
"The integration of Cloudflare with Cloud Suite is its most valuable feature."
"We're able to better manage network traffic with its analysis and security tools."
"We have seen a return on investment with Imperva Application Security Platform, as we started with a few devices and gradually increased the number of on-premises devices for Imperva Application Security Platform."
"The most valuable feature of Imperva, in addition to its strong knowledge base, is its effective protection for web applications."
"The most valuable feature of Imperva DDoS is to make our website available for our customers' requests 24 hours a day."
"The compliance is the most valuable aspect."
"Imperva is a Gartner leader, so its scalability, performance, and features are excellent."
"There are many features. There is ease of deployment. You can deploy the Imperva Web Application Firewall in two to three minutes. After that, you have to set the policies. For setting policies, you have toggle buttons. You can turn something on or off."
"Imperva DDoS helps us automate production. The client had specific requirements for a cloud project in the financial sector."
"I would give Radware Kubernetes WAF a rating of 10 out of 10."
 

Cons

"The reporting could be improved if it were more granular."
"They have some limitations with third-party integrations."
"The product can improve by having more multitenancy capability, which is currently not available."
"The ModSecurity core rules need to be updated."
"I have experienced some difficulties with Cloudflare's support as a customer based in India."
"The platform's control features related to real-time authentication and response time need improvement."
"The dashboard could be more user-friendly."
"The user interface is very simple and straightforward, but users need knowledge about DNS to accomplish tasks."
"The dashboard is not accessible on occasion."
"I think that better bot protection is needed in this solution."
"The weakest point of Imperva is their first level of support, which should be improved. They should also improve the access and security logs viewing directly on the portal. I would like to see better access and security logs through the portal and not only through a SIM solution. Currently, if you want to explore your access and security logs from Imperva, you need a SIM tool or a SIM infrastructure on your side to do it. You can't do it manually or directly through the portal, which is a big problem for us. I had a call yesterday with Imperva for the roadmap, and I just told them this. They agreed that this is an improvement point from their side."
"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."
"Imperva Web Application Firewall could improve the console by making it easier to use."
"Although we're only using it for the accelerator part, the purging of files and the way this feature functions could use improvement."
"The rules surrounding the making of web applications could be improved."
"The only disadvantage of Imperva is that it is a pretty costly solution."
"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

"Cloudflare offers different types of subscriptions for businesses, enterprises, and personal users, and the pricing is negotiable."
"We pay $210 per month for CloudFlare WAF."
"The pricing model is very straightforward compared to the competition. You just pay per month for the product and usage."
"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."
"It is not too pricey."
"It starts at $20 and can easily go up to $200 monthly"
"It is expensive."
"It's an excellent product, but it can be very costly."
"There is a license or subscription renewal that our customers pay."
"Imperva’s pricing is a bit higher in the market since it offers a full-blown WAF."
"The price is high compared to other solutions like FortiWeb."
"Imperva charges us based on bandwidth, which is better than other vendors that charge us according to data transfer."
"Make sure you understand the way that Imperva charges. It's very affordable. However, I would like to see a package with the Virtual Patching included. You get to do patching separately."
"I rate the product price a four on a scale of one to ten, where one is a low price, and ten is a high price."
