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.

I like the content monitoring feature which I haven't seen in other WAF solutions.
They could improve by minimizing false positive results. Although this occurs less with Imperva, we would like to see some further improvements. We have been using this product for last 1 years, it's result is very impressive. But due to the excessive load on the Web site where thousands of requests‎ are generated from legitimate users, however the request in which any sequential or specialised characters are requested would be directly blocked by impreva . Currently imperva blocks the special character request generated from the user, as I conduct a test where I am parsing the encoded html values of the same special characters to the input field, imperva bypasses these encoded values for example : ' i.e. %27 or / i.e %2F, the WAF bypasses these encoded characters. I hope that this device should have a capability to detect the pattern which is associated with Xss or Xsrf, rather then by not blocking the request which contains any special characters.

Helps to handle edge cases and has purge features
I believe Windows Azure CDN can improve monitoring and measuring overall end-user performance. Providing monitoring tools or agents that can be integrated into our pages would be highly beneficial. Setting up a custom domain with Windows Azure CDN involves proving domain ownership, which can take some time. The process is relatively straightforward if your DNS or domain registrar is already integrated with Microsoft. However, the verification process may be more time-consuming if you use a different service provider.

Quotes from Members

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

Pros

"Cloudflare has many features."
"The features of Cloudflare were found to be more beneficial and led to the decision to utilize it over other options."
"Even when there is a high load on our servers, Cloudflare is able to cache the data and serve it to users, ensuring they can still access the website."
"The tool is user-friendly."
"The DDoS protection is the most valuable aspect of the solution."
"Cloudflare allows us to self-host services such as Rocket.Chat and Node-RED, in high-availability mode, thanks to round robin DNS which allows us to share one hostname between our two locations."
"New and innovative way to protect the client's data."
"The most valuable feature is the web application firewall."
"On the site security, I can see which countries have incidents, whether it was a robot attack, a real human user, or non-human user."
"They're quite easy to install and quite easy to set up. Clients really like that. Especially when you're dealing with the cloud, it's really easy."
"Provides Anti-DDoS protection, as well as other protections like SQL injection, Cross-Site Scripting, and antiscanner. These types of protection are valuable to the business due to the daily attacks on our portals, and that often cannot be seen without a tool like this."
"This product is a reliable defense from malicious attacks on a network environment."
"Its unique interface for managing security performance and ease of use are the most valuable features of this solution."
"Setup was straightforward, very simple. I only entered the domain and Incapsula returned the DNS data that I needed to change for the protection to be configured."
"Real-time monitoring is also a great tool, as you may watch several parameters in real time."
"On the real time, you can see live traffic, which is flowing into our website."
"One of the most valuable aspects is the capability to store extensive datasets and objects in the cloud, enabling their download through shared access signatures."
"I enjoy engaging in discussions with colleagues possessing unique expertise. I leverage the three platforms—Azure, Google, and AWS extensively. This allows me to offer diverse solutions to customers, commonly referred to as a multi-cloud approach."
"The fact that it just delivers what it is supposed to do is its most valuable feature...The initial setup is very straightforward."
"The geolocation feature is very important because many colleagues travel worldwide and need to access information from anywhere. The product has improved security."
"We use the product for faster content delivery with low latency."
"The most valuable feature of the solution stems from the fact that one can access Windows Azure CDN from anywhere."
"It is a stable solution."
"One of the tool's best features is its ability to handle edge cases. For instance, we encountered a situation where we needed to remove certain files from public access. The solution offered a purge feature that allowed us to remove these files. This feature ensured that the files were deleted from all edge servers. Subsequently, we were able to upload new versions of the files."
 

Cons

"There could be more courses with engineers. I like e-learning, however, having a specialist in a classroom is more comfortable for me."
"Cloudflare does not have an on-premise solution. If they had different approaches they could be better suited to accommodate more customers, such as on-premise and hybrid deployments. For example, hybrid deployments would be useful where you could move the traffic from the enterprise to the cloud."
"The solution could be more user-friendly."
"Latencies are always a problem."
"It would be good if Cloudflare could have more servers for better traffic routing or an increase in the traffic routed. This is what I'd like to improve in Cloudflare."
"The product needs to improve its automation."
"Support response time could be improved."
"The pricing could be improved."
"Some maintenance must be performed by our IT team."
"We had an issue when securing the web applications for DDoS protection."
"It would be better if we were able to manage and apply changes to multiple websites/web applications, and search WAF logs for multiple websites, via the Incapsula dashboard."
"Incapsula services also provides load balancing services for their service IP address environment. So far, with monitoring their services, the IP address was only changed once."
"We faced issues regarding compliance with client procedures. The client had strict compliance rules, and Imperva needed to be on a VM, while the client required containerization, causing a conflict. They went with Imperva for the on-premise version but shelved the cloud project due to too many blockers."
"Imperva should have more points of presence in Africa."
"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."
"Certificate management could be improved."
"Exploring shared access solutions with cloud accounts would be a beneficial choice."
"The response time of the support team must be improved."
"We have experienced issues with switch connectivity."
"I believe Windows Azure CDN can improve monitoring and measuring overall end-user performance. Providing monitoring tools or agents that can be integrated into our pages would be highly beneficial. Setting up a custom domain with Windows Azure CDN involves proving domain ownership, which can take some time. The process is relatively straightforward if your DNS or domain registrar is already integrated with Microsoft. However, the verification process may be more time-consuming if you use a different service provider."
"There were a few bugs that were very disappointing. So, that is a part of the reason why we started using Fastly."
"I aim to enhance the reporting."
"The solution’s pricing could be improved."
"They should include configuration for cache rules."
 

Pricing and Cost Advice

"The solution is expensive when compared to other products but offers unlimited bandwidth."
"The pricing for the service is reasonable, neither excessively cheap nor prohibitively expensive. It aligns well with the value of their solution."
"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 cost primarily depends on the size of the organization."
"The price of the solution is expensive."
"There are no additional costs beyond the standard licensing fees."
"In terms of licensing costs, we don't pay for licensing for Cloudflare. We only establish communication, then for peering, Cloudflare takes care of the cross-connection in different data centers."
"I give the price a five out of ten."
"Imperva charges us based on bandwidth, which is better than other vendors that charge us according to data transfer."
"It is not expensive compared to the other similar solutions in this category."
"The cost is somewhere around $10,000 a site. For every site, you pay individually. For every DNS entry, you have you pay."
"The solution's price is high for small companies."
"The cost is on par with other solutions such as Cloudflare and Akamai."
"For enterprise contracts you will be in touch with a dedicated account manager who will guide you regarding licensing."
"​Although the pricing can be a little high, it is worth the protection and security that it offers.​"
"We are satisfied with the pricing."
"The pricing is extremely high, almost 9 out of 10."
"The solution's price depends on how much traffic you have. So, it was okay for us. Payments are to be made on a monthly basis since one has to pay for what they used."
"It comes at a relatively affordable cost."
"The tool's pricing is cheap."
"The solution's price is above the medium range."
"The tool's pricing is cheap."
"I rate the price of Windows Azure CDN a six on a scale of one to ten, where one is cheap, and ten is high."
"On a scale from one to ten, where one is cheap, and ten is expensive, I rate the solution's pricing a five out of ten."
