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.

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…

Multi-layered defense ensures robust protection and optimized resources
Radware DDoS Protection Service is valued for its multi-layered defense protection, always-on and on-demand service, zero-day protection with adaptive behavioral-based mitigation, DNS and infrastructure protection, and SSL attack mitigation. The solution's multi-layer protection covers volumetric, protocol-based, and application layer attacks. They offer a very effective response against DNS attacks. Regarding behavior-based detection technology, in terms of real-time detection, it has been able to reduce false positives. We have pretty good experience with them. The geolocation is pretty good for an organization such as ours. We can block anything from certain regions, like North Korea or China, etc, cetera. It works alongside machine learning. They can update policies globally in less than ten seconds, which really helps with false positives. During a DDoS attack, it ensures legitimate users are not affected. We're working on a hybrid solution, so we have Defence Pro devices on our side and unlimited mitigation capabilities on the cloud.

Quotes from Members

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

Pros

"The most valuable feature of Cloudflare is the GUI. You are able to control the solution very well through the interface. There is a lot of functionality that is embedded in the service."
"I like Cloudflare's application gateway and DDoS protection."
"The attacker won't have details since my public IP is anonymous. It offers us good privacy."
"I get a lot of value from Cloudflare's API because it enables you to build a separate environment inside the solution. You can create a domain for performing test requests before you move to the production environment and connect various domains."
"We're using dynamic components to build flexible pages to create and manage Git merge requests for code and reviews."
"Cloudflare makes it easier for me to handle and set up DNS for multiple users and multiple clients, and basically go in and access their account, make the changes they need, and it's a one-stop shop."
"The overall experience with Cloudflare is positive, with a rating of eight out of ten."
"The most valuable feature of Cloudflare DNS is security."
"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 DDoS protection features are valuable."
"The most important aspect, in general, is that the price is suitable for most clients."
"It is a good solution. Its vendor support is the most valuable. It is simple and works well if you have Juniper MX routers."
"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 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 dashboard is the best part, and there is also the ease of operations."
"The best feature is the auto mitigation of the DefensePro solution created by Radware."
"I am happy to see that we have not had any DDoS attacks. This solution has successfully protected us from attacks, and no one has been able to attack our network."
"A valuable feature is the speed of signature updates."
"All of our traffic has to pass through the appliance, so we can very quickly mitigate the attack. This is a very valuable feature. On top of that, it's not only volumetric attack protection that the solution offers, but also layer 7 attack protection as well."
"Radware DDoS Protection Service is valued for its multi-layered defense protection, always-on and on-demand service, zero-day protection with adaptive behavioral-based mitigation, DNS and infrastructure protection, and SSL attack mitigation."
"Recently, our company has been facing difficulties due to attacks originating from the Russian Federation. DefenseFlow has proven to be a highly effective solution in protecting our customers."
"This solution is extremely scalable and has the highest level throughput (100G) which complies with Telco deployment."
 

Cons

"Areas like how assessment, discovery, and payload are dealt with and how it all comes into your organization can be considered when trying to make suggestions to Cloudflare for improvements."
"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."
"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."
"Technical support is not well developed. While there are good engineers, Cloudflare does not offer hands-on technical support to fix customer problems but rather a self-service model."
"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."
"Eventually, things go sideways and require fixes when it would have been easier to prevent the issue initially."
"I would like Cloudflare to offer a dedicated account manager for large enterprise clients like us."
"The product support needs to be accessible from more places, a wider area of coverage."
"Lacks international presence."
"Corero needs to improve its application DDoS prevention capabilities and user behavior detection features."
"The product must provide more Layer 7 capabilities."
"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."
"It could use support in Spanish."
"This solution may not cover all of the requirements in situations for which I am unfamiliar, and there is always room for improvement."
"They need to increase the limit of devices that we can manage."
"There's room for improvement in the clarity of the feedback provided by the command service in the CLI."
"The product is good, but the company could improve its services by appointing customer success managers. This would ensure better interaction with customers and help resolve issues on both customer and supplier ends."
"I suggest improvements to the user interface to make it easier to use and to find the necessary data for analysis."
"The dashboard could be updated."
"The rise of generative AI and machine learning in cyberattacks demands more advanced defense strategies."
"Their Cyber Security Controller portal, including its GUI and dashboard, could be more intuitive so CXOs can easily understand them."
