Carlos Alam Hernandez Baruch - PeerSpot reviewer
Fast and secure deployments simplify operations for government and fintech clients
It is a fast and secure DNS. It is very easy to deploy, and my customers are happy with this tool. Additionally, the CDN performance in Mexico is excellent, providing fast service and tools. It offers reliability during high-traffic periods, ensuring no impact on the environment. It helps my clients avoid using on-premise boxes, simplifying operations as they only use the prices on Cloudflare.
Venkat Raju Mallipudi - PeerSpot reviewer
Acts as an additional layer of protection, provides endpoint security but not very easy to configure
It's not very easy to configure, in my view. We have to do some work behind the scenes. It's not very simple. We have to do it very carefully, and we need to monitor this enablement as well. But apart from that, I didn't see any kind of challenges. So, in my opinion, configuration is the main trouble for them. It is something that can be done to be better. Not just configuration. You need an expert who knows the ins and outs of these security solutions. In my experience, people struggle with configuration. While configuring, we get this error, we get that error, and then we try to fix those issues. I have seen those. It's not straightforward.
Yazan Omar - PeerSpot reviewer
An easy-to-use tool with great GUI
The product's initial setup phase was really easy. There is a lot of time involved in the testing phase and other processes related to the area of deployment, so it may take up to two weeks to deploy the solution. The solution is deployed on an on-premises model. One person is enough to take care of the deployment phase of the product. The person involved in the deployment phase needs to better understand topologies when dealing with Fortinet.

Quotes from Members

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

Pros

"The solution is stable, and the DNS servers are simple to use."
"The most valuable feature of Cloudflare DNS is security."
"Its ease of integration with Office 365 and the fact that it's a good product compared to what I had before"
"The most valuable feature of Cloudflare is that it has a free version. They give us the free version with the anti-DDoS features and also the load balancing solution."
"I like Cloudflare's application gateway and DDoS protection."
"DDoS attacks target unprotected machines. Cloudflare detects and stops these attacks using internal systems. It identifies incoming DDoS attacks, issuing challenges or blocking them immediately."
"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."
"From what I've seen so far, there are no negatives to report as of yet"
"Azure is easy to set up and widely used by our clients."
"The Azure DDoS Protection plan is essential for environments like ours that are highly exposed to potential attacks, especially since DDoS attacks have become common."
"Azure is easy to set up and widely used by our clients."
"Azure DDoS Protection offers superior protection against denial-of-service attacks."
"DDoS Protection is simple to deploy and integrates seamlessly with the Azure environment. Ease of deployment is a crucial feature for us."
"The most valuable feature of Azure DDoS Protection is that it performs well."
"AI capabilities are very good. I would rate them an eight out of ten."
"The integration of various tools with Azure Firewall, like DDoS Protection, Web Application Firewall, and Azure Front Door, is quite effective."
"Among its key features: Detects and mitigates DDoS attacks at L3 to L7; negligible to zero false-positives; Generates and sends reports without the need for an expensive third-party solution."
"The equipment works very well, and I have not encountered any issues with it. It is a good solution for my company."
"The product allows the users to adjust the thresholds."
"The product's initial setup phase was really easy."
"The solution is very user-friendly and very easy to use."
"This solution can protect Layer 3, Layer 4 and Layer 7 attacks of applications for us."
"The protection resources and the support are valuable features of the solution."
"It allows me to see all the traffic on my network."
 

Cons

"The tool needs to improve caching of servers. The product needs to include PFX certificate as well."
"There could be more courses with engineers. I like e-learning, however, having a specialist in a classroom is more comfortable for me."
"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."
"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."
"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."
"They lack a good way to manage DNS as a company, since everything is relegated to single account logins until you get to the higher levels. They have come out with a paid feature to remedy this, but I have not had a chance to fully review it yet to know if it fixes the access problem."
"One area of improvement is in the Access Rules. Hypothetically, if we wanted to block or challenge traffic outside of the United States, the only way to currently do that (as far as I know) is to enter every single country outside of the United States. That could be a labor intensive job. A solution could be to enable users to create a rule where traffic is only allowed within a certain country."
"DNS Management."
"The visibility could be better. We would like to have better metrics, so we could see all the information in a central place."
"I have noticed some false positives with the Web Application Firewall yet not with DDoS Protection."
"The dashboard lacks insights and user-friendliness, as most data is logged into metrics like Log Analytics workspaces."
"Azure DDoS Protection could improve on the reporting."
"The implementation of Azure DDoS Protection results in a decrease in our bandwidth capacity and should be optimized to reduce resource consumption."
"It's not very easy to configure, in my view."
"I suggest adding more services and additional services, which would be beneficial."
"Sometimes, it is hard for our staff to keep track of changes (in the GUI) between different projects, because there are constant changes. As a result, it is hard to manage, recall, and see all the features because they have been moved from one place to another."
"The primary area for improvement is the on-premises capacity limit, currently fixed at 10 GB."
"All the thresholds that need to be configured should be included in the default so that user will not forget or misconfigure."
"The challenge lies within the customer environment, particularly in Brazil, where companies have stringent security requirements for implementing solutions."
"The tool needs to focus more on the area of application traffic management, where it currently has some shortcomings."
"The web interface could be much better."
"I find that there have been issues in the past year with the solution hanging. It freezes often."
"The product’s pricing needs improvement."
"The solution can be a little more user-friendly and it can be more affordable."

"The product's pricing is cheap."
"It is an expensive solution."
