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.

Advanced protection has optimized web and API performance while reducing infrastructure costs
From the features perspective and functionality-wise, there are areas of Radware DDoS that I would like to see improved or enhanced in the future. Version upgrades are being provided, but they should communicate with clients about these new features being available so clients can test them and deploy them on the disaster recovery system before moving to the live segment. There should be a test report that will provide confidence that the version is stable and everything will work properly. Last time we faced an issue with a version upgrade, and we faced extensive troubleshooting with littile bit more time in the troubleshooting process. It turned out to be a small issue that was resolved by the engineering team. I would like to see improved support from Radware DDoS. Sometimes in support, we have to log the call with their support partners rather than Radware. After ten years of experience, we know exactly what the issue is, and we understand that it cannot be handled by their support channel or partner level. Radware team always asks us to go through the partners, but sometimes we have found that the issue cannot be handled by the partners. After the partners fail to resolve the issue, it goes to the Radware team. At that time, one to two days of required timeline gets increased by one to two days. If Radware came into immediate action and resolved the issue rather than relying on their service partners, it would be better. After ten years, we have the knowledge of troubleshooting, and we understand that the issues we are facing with Radware can only be resolved by their team. However, due to their policy, they insist we move through the partner first, and only after the partner fails do they escalate to Radware. During that troubleshooting period of twenty-four to forty-eight hours, we remain in an unresolved state with the reported issue.

Quotes from Members

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

Pros

"Scalability is awesome, and they have grown two folds or three folds since we started using them, with no concerns even as we protect close to 60,000 hosted sites for business and e-commerce customers."
"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."
"Radware DDoS has improved operational efficiency and helped save resources by automating DDoS detection and mitigation."
"The most valuable feature is the controller that determines when and how traffic can be moved to the cloud."
"The reporting is very good and provides us with a comprehensive description of where attacks are emanating from."
"During high-volume attacks, such as those during the Christmas and New Year periods, the solution protected our network perfectly, without any disturbance to our real-time users."
"Strong DDoS mitigation, good traffic visibility, automated protection, and cloud scalability. It provides useful telemetry during active security incidents."
"Now, after installing the Radware DefensePro anti-DDoS solution, they are 99% secure."
"The best features Radware DDoS offers are behavior-based detection and protection against Layer 3 attacks and Layer 7 attacks, along with encrypted traffic protection, automated mitigation, and hybrid deployment."
"Overall, I'm happy with this solution and what it has offered so far."
 

Cons

"Genuine traffic coming in is still getting better because sometimes while we are doing DDoS mitigation, genuine traffic does get blocked."
"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."
"Better integration with the automated incident response platform, and the ecosystem in general, would be an improvement."
"In terms of the defense devices, I would like to see an improvement within the implementation and upgrade phases."
"The solution needs a bit more functionality."
"The pricing structure could be lower, as not every organization can afford the current pricing."
"So far, I haven't found anything I dislike about Radware DDoS. Overall, I am satisfied with its performance, features, and customer support."
"Sometimes there is leakage in the network. Attacks go through without getting detected."
"During our last DDoS attack in February, we were setting up the system too strict. After some time, our protection started to kill our traffic."
"The solution is a little more pricey than other options on the market."
