It's easy to set up because you point the DNS to it, and it's working in under 15 minutes
Cloudflare is highly scalable. Cloudflare is a system with a web portal that the end users like me see. It's a console where we can adjust the DNS, caching, and security features all in that console. Cloudflare owns thousands of servers across the world that cache the data. It's a powerful solution. When clients sign up for Cloudflare, they're getting this monster content delivery network, security, and a web application firewall in one. It's all rolled into one, and it's massive. Unless you have your website hosted on a massive hosting provider, there's no way that you can deliver the amount of data that Cloudflare can provide to the end users. If you have static content, there's no way that you can ever match what Cloudflare can do. Obviously, there are competitors to Cloudflare that do the same, but I'm saying other types of solutions. Let's say you go with F5. Great, that's on-prem. That's in your colo. You can't deliver as much data to the internet as you can with a CDN. You don't have to spend $20,000 on a net scaler, F5, or whatever Cisco's selling now. You don't have to buy that. You pay them $50 a month or $150 a month. It's totally worth it because even in five years, you'll never get the performance value, not just the actual ROI. You have to consider how much throughput you can get with Cloudflare.

Offers bot protection and DDoS Protection and protects public-facing portals
Support is one thing I wish Imperva could improve. They follow the phone model and keep rotating you from one customer service person to another. The layer one support isn't very clear about the workings of the product. My feedback is primarily about Imperva Cloud, not on-premise. On-premise is a whole new story. Support is the issue for Imperva Cloud. It's also a bit pricey. It's a premium service and very expensive. The licensing model is not very straightforward. Every feature is priced separately, and to enjoy maximum protection, you'll have to spend a lot of money. The licensing model is a bit complex, and each feature is very pricey. For example, API security and web application protection are two separate license packages.

Allowed us to replace our reverse proxy, load-balancing, and WAF products with one platform
Perhaps the automatic reporting could be better. I would like to have seen more automated reports. Maybe it has been improved in the last year and I'm just not aware of it. But from a managerial point of view, you want a summary report, a weekly report: How many attacks were blocked? How much bandwidth was saved due to the caching mechanism? What were the top-ten attacks that were tested on the network, etc? I could most likely have found all that data if I logged in to the system and ran different reports. It would be very helpful to get a management report on a weekly basis.

Quotes from Members

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

Pros

"The most valuable feature is its usability."
"The attacker won't have details since my public IP is anonymous. It offers us good privacy."
"Centralized, full-featured DNS."
"The UI is good."
"There are key things that are used for our enterprise customers, such as Lambda and DNS."
"The solution automatically detects and responds to certain types of traffic based on geolocation."
"Its ease of integration with Office 365 and the fact that it's a good product compared to what I had before"
"I rate its stability a ten out of ten."
"Imperva monitors all traffic, even customer access, to the web application. Then, Imperva uses features like signatures to identify attacks like cross-site scripting or SQL injection."
"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."
"The most valuable features of the Imperva Web Application Firewall are DDoS, malware, and the other malicious threat prevention it provides. Additionally, third-party integration is available. You can forward the log for further analysis."
"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."
"The solution is scalable."
"One good thing about Imperva Web Application Firewall is it can be on the cloud and also it can be on-premise."
"The valuable features of Imperva WAF include its effective security breach prevention through automatically updating rules."
"The solution integrates seamlessly with other tools and has a good alert mechanism."
"I very much like the elastic search and reports, allowing us to have a 360-degree view of the customer's activities and enabling us to track down any suspicious bots."
"Reblaze knows how to manage security. For me as, someone who knows little about security, it's good that I have a firm that optimizes everything according to their standards. It's their responsibility and they are fully hands-on."
"Provides mobile app security."
"The most valuable features were the real-time monitoring and the management. With this kind of product, you need a very good management system to allow you to see false positives in real-time; to see what's happening in real-time... The clarity stood out. It was very visible and very easy to navigate; very easy to find the data we were looking for."
"The feature I find most valuable is the user-friendly dashboard. It is easy to understand how everything works and it allows you to make decisions quickly and efficiently."
"The main feature is using the rules and being able to see the traffic. It helps us find malicious traffic."
"The best thing about Reblaze, for us, is that it has been a game changer because previously, we were using Google's Web Application Firewall, but it wasn't up to the mark."
"It is a highly resilient product that can handle significantly larger workloads and high volumes of traffic with ease."
 

Cons

"The analytics, basically the dashboard, doesn't have much to it."
"The integration of LLMs on the dashboard is something that is needed in the tool."
"The reporting can definitely be improved to offer a lot more explanation on something that may have happened or has actually happened."
"It should have easier documentation for the configuration. It's very technical and people who aren't technical should also be able to do the configuration."
"Technical support is lacking."
"For large enterprises, the pricing is okay. However, the enterprise price for small projects is a bit high. A mid-tier pricing option would be beneficial."
"For the free and Pro plans, Cloudflare could use a simple bot to provide information to users. This would improve support, especially for less advanced users who utilize the free components."
"Sometimes their more advanced caching tools can cause higher first-byte times and problems with JavaScript."
"Sometimes our web application firewall will slow down."
"Imperva Web Application Firewall can improve by adding more features to the dashboard. increasing the visibility of the real-time events, besides configuring the administration itself."
"It would be helpful to have a "recommended deployment", or even a list of basic features that should either be used or turned on by default."
"There's always room for improvement. Occasionally, there might be false-positive alerts."
"Imperva Web Application Firewall could improve the console by making it easier to use."
"I would like the solution to improve its support response time."
"The UI interface needs improvement."
"I think that better bot protection is needed in this solution."
"The WAF features are not as granular as we would expect from a WAF system. There should be more granularity and in-depth rules, out-of-the-box."
"They have an interface that you have to adjust to. That is a bit of a downfall because I expect an interface to be very intuitive for someone who knows little about security. But if you know about security, the interface is wonderful."
"I would like to have seen more automated reports. Maybe it has been improved in the last year and I'm just not aware of it. But from a managerial point of view, you want a summary report, a weekly report: How many attacks were blocked? How much bandwidth was saved due to the caching mechanism? What were the top-ten attacks that were tested on the network, etc? I could most likely have found all that data if I logged in to the system and ran different reports. It would be very helpful to get a management report on a weekly basis."
"Up to now the only cons I could find is sometimes getting change management back on track, because it's a company that evolves, and sometimes I don't have the same needs that they have. But besides that, up until now, I am really pleased with their service and I've also recommended them to some of my clients."
"The next release should have next-generation automation."
"There is room for improvement in helping us understanding session management... We want Reblaze to catch and identify everything. We want to see the various devices doing one activity and to see, in a timeline, what's happened. We would like to see a more human-readable display to understand what's happening in the web app."
"Some of the settings on the dashboard are confusing."
"It would be beneficial if it had a workflow or a feature that could fine-tune settings based on high-level requirements."
 

Pricing and Cost Advice

"There are no additional costs beyond the standard licensing fees."
"That is one of the great features. I was able to access the majority of the features and services for free."
"We are using the free tier of the solution."
"The solution has many features but there are ones that you need to pay for. Sometimes you have to find out which is available for free and which you have to pay for."
"The price is reasonable."
"The tool is a premium product, so it is very expensive."
"I believe their performance has improved, but I'd like to refrain from discussing the pricing aspect related to the cloud. The pricing, in my opinion, could be simplified, and I think they should consider reevaluating the pricing for support, as it can be quite high. At times, this cost can make it challenging to choose CARFAGuard or opt for the support."
"The product's pricing is cheap."
"Imperva’s pricing is a bit higher in the market since it offers a full-blown WAF."
"There are a couple of different licensing models."
"Licensing can range from one to twenty thousand dollars annually. Additionally, some features, including software support, require an annual subscription as well."
"The tool is expensive."
"Imperva Web Application Firewall is expensive."
"The solution's pricing is an issue."
"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."
"It is a very affordable solution."
"We found the cost to be a bit on the higher side, starting at approximately three to four thousand dollars for a small configuration."
"On a monthly basis we pay $750."
"I believe that for the six instances we have right now, it's costing us $16,000 per month."
"There is still some room for improvement when it comes to bot management from Reblaze because they are relatively new compared to other vendors in the town."
