Has helped manage client domains with streamlined access control and threat visibility

I don't know what areas could be improved with Cloudflare WAF; Cloudflare is constantly improving and adding features to their feature set. They're doing a good job, and as far as DNS and support for any domains that I create or my clients create, it's mandatory for me to make sure that they have Cloudflare as their DNS provider. The Cloudflare load balancing capability hasn't really helped in enhancing my website's uptime and resiliency because we don't really get that much traffic; it's mostly remote users, and web hosting is done by a web hosting service. It doesn't pay to try to host your own website.

Identifies a request that comes up multiple times, block holds that particular IP, and lets the genuine traffic pass through

Genuine traffic coming in is still getting better. While I understand that it's some sort of algorithm that is written in this scale, that algorithm can be a little bit better because sometimes while we are doing DDoS mitigation, genuine traffic does get blocked. While it is one of the greatest features it can still be improved. I would like to see a dashboard that shows you the data that is transferred from which end. It's where people start looking at abuse management. People keep questioning when the mitigation is on what service it is and how many GBs are passing through. An end user dashboard that will help you identify all of these questions and that can be visible in your entire organization is something that would make sense.

Quotes from Members

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

Pros

"When using services like Heroku, Cloudflare is very useful for CNAME flattening. I also use it for their end-to-end SSL with TLS authentication on nginx for securing servers."

"The most valuable features of the solution are performance and security."

"Cloudflare has many features."

"Smaller businesses have seen great ROI due to the low investment and strong performance."

"The technical support is good."

"What I like best about Cloudflare is that my company can use it to trace and manage applications and monitor traffic. The solution tells you if there's a spike in traffic. Cloudflare also sends you a link to check your equipment and deployment and track it through peering, so it's a valuable tool."

"The solution is stable, and the DNS servers are simple to use."

"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."

More Cloudflare pros

"In the DDoS it's difficult to validate what is a genuine request from an end user. We've started being able to do that with the logistics that they have set up. With the protection that they have provided, they are able to identify what is valid and what is not valid. We see that a person who is getting DDoS Neustar service is able to block that particular user. However, while they are doing that it doesn't affect other customers on the server."

Cons

"The solution could be more user-friendly."

"If they improve on the placement of their data centers, it would be better. I'm living in a remote area. I would like to connect to them without any kind of lag."

"We're facing challenges due to an upgrade in the machine learning model. The problem arises from some users abusing the APIs, resulting in an influx of suspicious traffic. Cloudflare's learning model mistakenly identifies this traffic as human. Consequently, it assigns it a higher trust score, akin to legitimate human traffic, causing complications in our architecture. Previously, such traffic would have been categorized as suspicious, enabling us to apply appropriate blocking rules. However, we encounter difficulties distinguishing between genuine and suspicious traffic with the new categorization. Despite these challenges, overall, Cloudflare remains the preferred solution compared to Azure, AWS CloudFront, and Google Cloud Armor."

"Cloudflare should add more documentation and pricing to the cloud version."

"There are some issues with the CDN services."

"The documentation could improve for Cloudflare DNS."

"Cloudflare could offer a better view or maybe dashboards of the main resources used in the client."

"Even if I wanted to, I wouldn't be able to buy Cloudflare in my country."

More Cloudflare cons

"I would like to see a dashboard that shows you the data that is transferred from which end. It's where people start looking at abuse management. People keep questioning when the mitigation is on what service it is and how many GBs are passing through. An end user dashboard that will help you identify all of these questions and that can be visible in your entire organization is something that would make sense."

Pricing and Cost Advice

"The price of the solution is expensive."

"We are using the free tier of the solution."

"I think the pricing is competitive. I think as far as licensing is concerned it's pretty straightforward because it's based on domain. It's just that sometimes domains could be tricky with some customers."

"There are no additional costs beyond the standard licensing fees."

"The pricing for the service is reasonable, neither excessively cheap nor prohibitively expensive. It aligns well with the value of their solution."

"So far I use free tier and happy with it. You can subscribe to business package if needed."

"When you compare Cloudflare DNS to other solutions, such as Akamai, the price is reasonable."

"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."

Of course, we would enjoy providing information to inquiring parties. The question I have is that you asked about DDoS protection, but the request is about DNS Services. If you can clarify, that would help me with a proper response.
