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.

Helps us to monitor attacks to our sites and prevents a lot of them
Set up Wallarm as a reverse proxy. Do not replace your web server. Use Wallarm first in monitoring mode, then learn from Wallarm which type of request is false positive and which type of request is not. This process takes a couple of weeks for very highly-loaded web applications (few millions of unique visitors in one month). Then you can turn Wallarm into blocking mode and everything will be fine. Do not forget to build a monitoring system, the wave, and API for it. Before we started using Wallarm, I already knew Ivan (CEO) and Stepan (COO) from a couple of years before. Ivan had his own security company and Stepan was working on a Russian security magazine called Xakep. They told us that they wanted to create a new WAF and already had a working version of it. They asked me to test it. We did tests, and it was really good. After few month after testing, we signed an agreement. Our choice was made not because we knew these guys for a long time, but because the product was really cool and we were glad to start using it as one of the first on the market!

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."
"The product has improved our security posture by blocking bad actors."
"Cloudflare WAF provides protection through rules and functionalities like Cloudflare's SDRAP."
"Technical support has a very fast response time and they are helpful."
"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 stability of Cloudflare Web Application Firewall deserves a perfect 10 out of 10."
"The setup process is very simple for me."
"Cloudflare is cheaper compared to Azure WAF, which I have considered before."
"The tool's profiling feature maps all the web application directories and related components on the profile directory. It has improved the security of my client's website applications."
"It mitigates all of the availabilities of risks around web applications."
"Learning mode and custom policies are helpful features."
"The Web Application firewall is a valuable feature as the security features are mostly what we're interested in."
"The most valuable features of Imperva Web Application Firewall are the monitoring of databases and the dashboards are easy to understand."
"This product is a reliable defense from malicious attacks on a network environment."
"The solution is scalable."
"The most important feature I have found to be the ease in how to do the backup and restores."
"They are the only solution that fits our success criteria and business objectives: WAF must have a low (<5%) false negative rate and be ready to protect from all well-known web attacks."
"Vulnerability scanner and WAF are valuable features."
"With active threat detection, we are no longer over-swamped with tons of useless events."
"Perimeter control and active vulnerability scanner are the most valuable features."
"Helps us to monitor situation in regards to attacks to our sites and prevents a lot of them."
"The most powerful feature is the ability to first learn what type of query to make to your web application when it is attacked and what type of query creates a false positive to your app."
 

Cons

"The product can improve by having more multitenancy capability, which is currently not available."
"WAF doesn't directly affect bandwidth costs. It saves costs on protection. However, with the correct setup, it's difficult to determine if it saves costs overall due to the fixed enterprise plan fee."
"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 ModSecurity core rules need to be updated."
"Cloudflare Web Application Firewall should improve visibility for a customer."
"The reporting could be improved if it were more granular."
"Their documentation could be better. They don't have documentation that explains everything well."
"The user interface is very simple and straightforward, but users need knowledge about DNS to accomplish tasks."
"I think the pricing needs some tweaks."
"Its price could be improved. It is quite expensive. It will be good if we could export the configuration. Currently, to control the configuration, we need to go to each website, which is not very convenient."
"Some of the features should be included in the next release is a file integrating monitoring tool. This feature should be improved."
"Imperva Application Security Platform could be improved by providing a more user-friendly dashboard."
"We would like them to hire people in Sweden because it's quite hard when people are sitting in the UK or Belgium because some of the customers really want them to be local."
"The product's customization capabilities are a bit problematic, requiring support cases for backend modifications."
"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."
"We rate technical support as really bad."
"Technical support is 6 or 7 out of 10. Sometimes we have had trouble with communication and understanding."
"It needs more customization in PDF reports."
"Wallarm uses a learning mechanism to detect attacks and to avoid false positives. If Wallarm blocks some illegitimate request, then you can go to the management console and mark this request as false positive, but sometimes this does not work properly."
"The biggest problem for us was the stability and speed using the first version of Wallarm. Now, it is fine."
"There were several stability issues during the first pilot."
 

Pricing and Cost Advice

"It starts at $20 and can easily go up to $200 monthly"

"Pricing could be more competitive."
"Licensing can range from one to twenty thousand dollars annually. Additionally, some features, including software support, require an annual subscription as well."
"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."
"Imperva charges us based on bandwidth, which is better than other vendors that charge us according to data transfer."
