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

"Does a good job preventing web application attacks."
"Cloudflare is cheaper compared to Azure WAF, which I have considered before."
"The security features are valuable. The particular feature we use is called OWASP."
"Caching is the most valuable feature of Cloudflare Web Application Firewall."
"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."
"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."
"I'm highly satisfied. It's remarkably user-friendly, enabling me to quickly identify issues, and deploy solutions, and it offers the necessary features."
"The integration of Cloudflare with Cloud Suite is its most valuable feature."
"I find the configurability of the tools and the ease of operation to be the most valuable feature of Imperva."
"Very scalable and very stable firewall for web applications, with a good interface in its cloud version. Mitigation is its most valuable feature. The technical support for this product is also good."
"There are a number of features that are valuable such as the account takeover and various antivirus features."
"Anti-DDoS protection, as well as other protections like SQL injection, Cross-Site Scripting, and antiscanner, are valuable to the business due to the daily attacks on our portals that often cannot be seen without a tool like this."
"There is no need to have an in-house WAF to manage and maintain; we are now able to bring a new website live within minutes, without false positive alerts, and it has improved user/customer experience and website performance."
"There are quite a few useful Imperva Incapsula features. For example, one of them is the reports. The graphics are very good and it's easy to configure. The whole process is very fast and reliable too. They have good tech support as well."
"The setup of Imperva DDoS was easy and we are satisfied with the pricing."
"The complete solution is valuable for everything it delivers and the protection it offers."
"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."
"Helps us to monitor situation in regards to attacks to our sites and prevents a lot of them."
"Perimeter control and active vulnerability scanner are the most valuable features."
"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."
"With active threat detection, we are no longer over-swamped with tons of useless events."
"Vulnerability scanner and WAF are valuable features."
 

Cons

"It would be ideal if the solution offered better log integration and more integration with different platforms."
"If they add logs history within the Cloudflare offering, that would be a great benefit."
"The blocked logs are difficult to read at times."
"The rate limiting functionality could be enhanced, as we find it somewhat limited."
"Cloudflare Web Application Firewall should improve visibility for a customer."
"The reporting could be more granular."
"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."
"Their documentation could be better. They don't have documentation that explains everything well."
"They once terminated a free account without warning, resulting in a few days downtime."
"There is nothing specific where the application firewall is falling short."
"The process to upgrade from one version to another can be a lot simpler than it is currently."
"If I had the opportunity to recommend an enhancement to Imperva it would be to have more POP (Point of Presence) in East and West Africa, and in Central Africa as well."
"Customer Service: Average to poor. Technical Support: Average to poor."
"It would be nice to have a mobile app as a dashboard interface instead of the web administration, but the service is really great."
"Their customer service sometimes has different responses for similar requests. We sometimes need to explain the issue many times before they understand."
"The log analytics interface within Incapsula isn't really good. For example, if you have to get all logs from there, it's a very cumbersome process."
"The biggest problem for us was the stability and speed using the first version of Wallarm. Now, it is fine."
"Technical support is 6 or 7 out of 10. Sometimes we have had trouble with communication and understanding."
"There were several stability issues during the first pilot."
"It needs more customization in PDF reports."
"The biggest problem for us was the stability and speed using the first version of Wallarm."
"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."
 

Pricing and Cost Advice

"We pay $210 per month for CloudFlare WAF."
"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."
"Cloudflare Web Application Firewall is more affordable than other solutions."
"Cloudflare offers different types of subscriptions for businesses, enterprises, and personal users, and the pricing is negotiable."
"It starts at $20 and can easily go up to $200 monthly"
"It is not too pricey."
"The solution's pricing option needs to be more transparent for enterprise clients."
"The solution is expensive."
"The tool's pricing is good."
"It is a very expensive solution. The price is very high. A lot of customers tell us that they would love to use Imperva more. I have some customers who have 50 websites, but they have only 10 websites on Imperva because of the price. They would love to have all their websites running through Imperva, but they can't. They have to choose the more critical websites to protect because the price is very high. It is a very good product, but it is too expensive. If you buy a plan for 20 megabytes and you don't consume all of your 20 megabytes, it is okay, but if you consume more, you are charged for the superior traffic."
"The cost is somewhere around $10,000 a site. For every site, you pay individually. For every DNS entry, you have you pay."
"There is a license for this solution and we purchase the license annually with no additional fees."
"Imperva Web Application Firewall is expensive."
"The price is high compared to other solutions like FortiWeb."
"The data packages are higher than our needs so we end up paying for data that we don't use."
"It is a very affordable solution."
"​Pricing must be cheaper than the competition and the licensing must be good.​"
