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.

Quotes from Members

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

Pros

"The simplicity of the overall dashboard makes it a great product for a user like me who has less understanding of the internet than a developer or other more technical people. It gives me peace of mind. I also love the easy customization of the Page Rules."
"Its ease of integration with Office 365 and the fact that it's a good product compared to what I had before"
"Many websites require an SSL certificate because they sell stuff and want SSL. Cloudflare comes with an SSL certificate built in. It's automatic. You sign yourself up for Cloudflare, and an SSL certificate automatically protects your website. You don't necessarily need a certificate if you have a connection between your website and your host, the server, Cloudflare, and the host."
"The solution offers the flexibility to control configuration rules."
"We're using dynamic components to build flexible pages to create and manage Git merge requests for code and reviews."
"Generally, I am satisfied with this product."
"The most valuable feature is the web application firewall."
"The most valuable feature of Cloudflare DNS is its global reach and it is always evolving."
"The solution is scalable."
"Imperva Web Application Firewall is stable."
"The most valuable features of Imperva Web Application Firewall are the monitoring of databases and the dashboards are easy to understand."
"Learning mode and custom policies are helpful features."
"Imperva has a complete picture of how the applications are utilizing it. It is handy. DDoS is good. It has an internally managed database. It is very easy to integrate. We have integrated it with SIEM services."
"It has fewer false positives"
"It works right out of the box once you integrate the application."
"The solution can scale."
"The most valuable feature of Microsoft Azure Application Gateway is its ease of use."
"The solution has built-in rules that reduce alerts and are easy to configure."
"The solution integrates different applications and APIs securely, enhancing overall security and network optimization."
"We find it valuable because it is compatible with our existing Azure solution."
"The solution provides great automation and it is easy to upgrade service."
"This is a SaaS product, so it is always up to date."
"It does an excellent job of load balancing."
"Microsoft has a vast variety of tools, and it blends very well."
 

Cons

"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."
"The product needs to improve its automation."
"An integrated SSO feature would be useful for Cloudflare DNS."
"Support response time could be improved."
"Integration involving API with other products could be more user-friendly."
"Cloudflare should add more documentation and pricing to the cloud version."
"There are some issues with the CDN services."
"I believe they currently have this feature, but there will most likely be integration with APIs so we can control some features through API."
"I loved the approach of the cloud. The cloud has a lot of new features, like advanced web protection and DDoS protection. If those could also be on-boarded onto the on-prem versions, that would be ideal. They need to pay attention to both deployment options and not just favor one."
"Some of the features should be included in the next release is a file integrating monitoring tool. This feature should be improved."
"The initial setup could be simplified. Every time you have to install the solution you have to get in touch with support or somebody that can to do that for you."
"In the past, I have bugs on the WAF. I've contacted Imperva about them. Future releases should be less buggy."
"The tool needs to improve CPU and storage memory."
"One potential improvement for Imperva is enhancing its alert system."
"I don't really use it and therefore can't speak to areas of improvement."
"Their portal is very limited and needs improvement."
"The pricing of the solution is a bit high. The solution should offer different pricing systems."
"Application Gateway’s limitation is that the private and the public endpoint cannot use the same port."
"In the next release, the solution could improve the integration with Service Mesh and other Azure Security Services."
"The working speed of the solution needs improvement."
"The product's performance should be better."
"The solution needs improvements in integrating different services and creating a better application balance."
"The monitoring on the solution could be better."
"One of the challenges we faced was the solution does not support any other PCP protocols apart from HTTP and HTTPS."
 

Pricing and Cost Advice

"So far I use free tier and happy with it. You can subscribe to business package if needed."
"I give the price a five out of ten."

"The price is reasonable."
"Cloudflare's pricing is not much higher and is good for middle-level organizations."

"We don't have any issues with the price."
