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.
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.

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

"It is a fast and secure DNS."
"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."
"It's a great product because it's scalable, has great coverage, and is mature with good defenses against DDoS attacks."
"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."
"Cloudflare is a security SaaS provider that provides security and protects us from any application layer attack."
"The most valuable feature is its usability."
"The most valuable features of the solution are performance and security."
"It is a fast and secure DNS."
"It allows me to see all the traffic on my network."
"The solution is very user-friendly and very easy to use."
"The product allows the users to adjust the thresholds."
"We have researched them all, and it's a good solution all around."
"This solution can protect Layer 3, Layer 4 and Layer 7 attacks of applications for us."
"It is a user-friendly product in terms of monitoring and updating policies."
"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."
"The pricing is reasonable. It's not overly expensive."
"The best feature is the auto mitigation of the DefensePro solution created by Radware."
"It's very good at protecting users from DDoS attacks. It's the leader in this domain."
"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."
"The most important part is that Radware DDoS integrates seamlessly and provides anomaly identification, real-time notifications, and security against DDoS attacks. It also helps us with multi-layer volumetric attacks. It shields us from global botnet threats."
"Its functionality is very good."
"The best feature of Radware DDoS Protection Service is the automation. Previously, manual intervention was necessary, and for incoming attacks, we had to inform the respective security and operations teams, whereas now, it is an automated process that blocks attacks based on policies by default."
"They have a hybrid model approach if a client wants to go that way."
 

Cons

"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 helpful if the solution could continue evolving to compete with the other solutions on the market."
"There are some issues with the CDN services."
"There could be more courses with engineers. I like e-learning, however, having a specialist in a classroom is more comfortable for me."
"The product support needs to be accessible from more places, a wider area of coverage."
"There might be helpful if there was some web application firewall feature."
"The product needs to improve its automation."
"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."
"The solution can be a little more user-friendly and it can be more affordable."
"The challenge lies within the customer environment, particularly in Brazil, where companies have stringent security requirements for implementing solutions."
"The only thing they need to do is to automate it. Today, you must create tools that do not require the use of an expert or anyone with special skills."
"There aren't really any aspects of the solution we are unhappy with. It's been a positive experience overall."
"The web interface could be much better."
"The primary area for improvement is the on-premises capacity limit, currently fixed at 10 GB."
"The product’s pricing needs improvement."
"Alerts and reporting features must be improved."
"Radware's management is very proactive, but Radware's lower-level staff is not proactive. You need to do a lot of follow-ups."
"The inability to access local technical support during our business hours poses a significant inconvenience."
"The dashboard could be updated."
"As a service provider, we are expecting the multi-tenancy feature on the dashboard and reporting side. It will help share reports with customers in real-time. They can directly see them online. We are working with their team on API integration with our portal. We will be able to achieve that, but it will take some time."
"Radware DefensePro requires a continuous learning process. Using this technology, we can improve our network. Based on the different attack mechanisms, we use Radware DefensePro to provide security for our clients' networks very effectively."
"We would like to have seven-layer functionality."
"I think Radware DDoS Protection Service could be improved by enhancing the network analytics features."
"This product would be improved if ongoing live monitoring with dashboards were added."
 

Pricing and Cost Advice

"A free version of the solution is available."
"The solution has many features but there are ones that you need to pay for. Sometimes you have to find out which is available for free and which you have to pay for."
"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."
"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."
"So far I use free tier and happy with it. You can subscribe to business package if needed."
"I give the price a five out of ten."
"Cloudflare's pricing is not much higher and is good for middle-level organizations."
"The product’s pricing needs improvement."
