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.

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 Cloud DDoS Protection Service stands out with its real-time threat detection, automated DDoS mitigation, and ability to maintain business application availability while allowing legitimate traffic."
"It ensures both security and performance. It achieves this by learning behavior patterns and providing protection without blocking normal traffic."
"The initial setup is easy."
"Radware DDoS has positively impacted my organization by sorting unwanted traffic, specifically malicious traffic targeting the applications, and it has taken the burden off the perimeter firewall during incidents."
"The important features include automated protection and defense against many attacks, it's important that our networks are protected in the Radware cloud."
"The pricing is reasonable. It's not overly expensive."
"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."
"Knowing that suspicious traffic is identified and blocked automatically gives our team more time to focus on strategic tasks rather than reacting to incidents while ensuring our application remains available to users."
 

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."
"The rise of generative AI and machine learning in cyberattacks demands more advanced defense strategies."
"There should be some extra layer of security and a method of advanced rate limiting. We can limit the number of IPs or URLs per session and per country. There should be improved bot management integration that mitigates bot-based DDoS attacks completely."
"I want to improve the blocking time; it should be within 10 seconds because 18 seconds allows multiple transactions in the financial industry."
"I am satisfied with the solution, but improvements in reporting, customization, and dashboard flexibility would add more value."
"Pricing has room for improvement. It is somewhat inconvenient for us because the new features that are introduced are pricey and are just add-ons to the original or baseline license."
"It currently takes about 15 to 20 minutes for the process to complete, which should be minimized."
"When the core services and the ERP are exposed to the internet, Radware DDoS has not managed to mitigate any specific attack with major impact that I can recall."
"As price increases based on the volume of net traffic, it can get expensive."
 

Pricing and Cost Advice

Information not available
"The pricing is based on the amount of network traffic and the number of packets being inspected."
"Radware's Cloud DDoS Protection Service stands out for its competitive pricing, making it a strong contender in our decision."
"I rate Radware DefenseFlow's pricing an eight out of ten."
"The product's pricing is a good value."
"Its pricing is competitive. The licensing model is also very competitive. It is customizable, so there is no issue at all. They have given us whatever we have asked in terms of the pricing model and SLA."
"Radware DefensePro is expensive when considering the issue we have and its limitations."
"The price varies by use case and there are monthly and annual licensing options. If you deploy on-premise, there is an annual license with the amount dependent on the throughput you need and which features you will be using - i.e. IPS, behavioral, etc."
"It is expensive. I would rate it a seven out of ten for pricing."
