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.
Björn Lindman - PeerSpot reviewer
The product is highly stable and has valuable features, but it must provide more Layer 7 capabilities
We use the solution for DDoS protection in the routers The DDoS protection features are valuable. The product must provide more Layer 7 capabilities. It must provide deep inspection features. I have been using the solution for ten years. The tool has high stability. I rate the stability a nine…

Quotes from Members

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

Pros

"The solution automatically detects and responds to certain types of traffic based on geolocation."
"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."
"The UI is good."
"We're using dynamic components to build flexible pages to create and manage Git merge requests for code and reviews."
"Its most significant benefit to date is the speed with which it refreshes DNS records on the internet once you change it. If you are changing a website or registering a new record, it is very quick."
"Cloudflare has many features."
"Easier http to https redirect using page rules"
"The solution is stable, and the DNS servers are simple to use."
"This solution is the best option for us because we use a lot of Microsoft products. So, it is easy for us to deploy or integrate any features or products."
"Azure is easy to set up and widely used by our clients."
"The most valuable feature of Azure DDoS Protection is that it performs well."
"Azure is easy to set up and widely used by our clients."
"The integration of various tools with Azure Firewall, like DDoS Protection, Web Application Firewall, and Azure Front Door, is quite effective."
"AI capabilities are very good. I would rate them an eight out of ten."
"Azure DDoS Protection offers superior protection against denial-of-service attacks."
"The integration of various tools with Azure Firewall, like DDoS Protection, Web Application Firewall, and Azure Front Door, is quite effective."
"The most valuable feature of Corero is its ability to handle smaller attacks in terms of the amount of volume and time. You can handle almost 100 perfect of the attacks locally."
"It is a good solution. Its vendor support is the most valuable. It is simple and works well if you have Juniper MX routers."
"It is an agnostic and transparent inline platform, which means that the maximum visibility of the symmetric and asymmetric traffic is available, even allowing bidirectional detection of the attack."
"The DDoS protection features are valuable."
"SmartWall devices occupy only one-fourth of the width of a rack unit, making them very easy to install."
"This is a hybrid solution."
"The most important aspect, in general, is that the price is suitable for most clients."
 

Cons

"Eventually, things go sideways and require fixes when it would have been easier to prevent the issue initially."
"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."
"There should be a specific price list for enterprise-level customers."
"The solution could be more user-friendly."
"It would be helpful if the solution could continue evolving to compete with the other solutions on the market."
"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."
"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."
"There could be more courses with engineers. I like e-learning, however, having a specialist in a classroom is more comfortable for me."
"The dashboard lacks insights and user-friendliness, as most data is logged into metrics like Log Analytics workspaces."
"I suggest adding more services and additional services, which would be beneficial."
"I have noticed some false positives with the Web Application Firewall yet not with DDoS Protection."
"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."
"It's not very easy to configure, in my view."
"The visibility could be better. We would like to have better metrics, so we could see all the information in a central place."
"The implementation of Azure DDoS Protection results in a decrease in our bandwidth capacity and should be optimized to reduce resource consumption."
"Azure DDoS Protection could improve on the reporting."
"The approach taken by Corero is to partner with other organizations in order to address volumetric attacks that cannot be handled by the hardware installed in the infrastructure. Corero does not have a solution for these attacks, so they are looking for partners to help them manage them. This approach is supplemented by local hardware, but the main focus is on the partnerships. It would be beneficial to have a more complete solution."
"Juniper is known in our country, but it is not very popular. There is also not enough information about Corero. Our enterprise and financial sectors don't know about this solution. They need to provide more information and do more marketing for this solution in our country."
"Corero needs to improve its application DDoS prevention capabilities and user behavior detection features."
"It could use support in Spanish."
"Lacks international presence."
"The product must provide more Layer 7 capabilities."
 

Pricing and Cost Advice

"The tool is a premium product, so it is very expensive."
"We don't have any issues with the price."
"For Cloudflare, I recommend it heavily for small businesses with revenue under a couple of million dollars. Onboarding is easy, and they even have a free plan. This makes it simple for businesses in the $100,000-$500,000 range to try it out and see its value, allowing them to scale up their infrastructure as needed."
"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."
"When you compare Cloudflare DNS to other solutions, such as Akamai, the price is reasonable."
"It's a premium model. You can start at zero and work your way up to the enterprise model, which has a very high pricing level."
"The price of the solution is expensive."
"I give the price a five out of ten."
"You can test it for a certain period of time free of charge. You can have a free account. You can test it to compare its pros and cons with other products that you are testing."
"It is an expensive solution."
"The price of Corero is affordable."
"Its price is normal."
