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.

It's not easy to get out once you're in
Sitelock may perform a useful service, but be wary of giving them your credit card information. When you sign on for the paid service, Sitelock: * Hides (makes it difficult to find) that they default the auto-renew (you can't sign up without agreeing to have them automatically bill your credit card every year). * Hides (makes it difficult to find) how to stop auto-renew: * You can't just stop auto-renew from your billing panel, the way you can with reputable businesses. * You have to hunt their website for a link (in extremely small font) to the page which contains instructions for cancelling. * When you get to that page, turns out it's the 5000+ word "Terms of Service" document, which you have to scour to find a phone number. Then, you have to call and get put on hold (or if you like, they will call you back three days later). Once you finally get through, you have to jump through a lot of security hoops. All of the above, just to cancel the service. Their product may or may not be OK, but be forewarned that with Sitelock, it's not easy to get out once you're in.

Quotes from Members

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

Pros

"Radware DDoS Protection Service is valued for its multi-layered defense protection."
"Their tech support is fantastic."
"The initial setup is simple, the deployment should take no more than one or two days, and the support from Radware is very helpful."
"I've been using this solution for the past two and a half years at my company, and I’m pleased to share that we’ve successfully achieved all of our use cases with their services."
"The most valuable feature is the ability to create signatures on-demand."
"The clean traffic is actually the favorite feature that we have, and that is one of the reasons why we went with Radware instead of other solutions."
"This solution is extremely scalable and has the highest level throughput (100G) which complies with Telco deployment."
"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."
"Not only did SiteLock's website scanner find the issue with my website, but with SiteLock I was able to implement a security system to prevent future breaches."
"It seems to provide a bit of useful information on website health."
 

Cons

"They didn't listen to what we were asking for and what we needed."
"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 needs to improve its communication with users."
"Multiple times errors and issues show that legitimate traffic can be dropped, as the system is not understanding the particular customer's ports."
"Better integration with the automated incident response platform, and the ecosystem in general, would be an improvement."
"There is room for improvement in the pricing; the product could be more affordable."
"I think the ease of use of the Radware DDoS interface requires a bit more advanced knowledge, and there are applications that are much more intuitive."
"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."
"Sitelock may perform a useful service, but be wary of giving them your credit card information."
 

Pricing and Cost Advice

"The price was well over six figures."
"Radware DefensePro is a bit on the expensive side."
"The Radware DefensePro was bundled together with our security platform."
"It is sort of middle-of-the-road for this type of solution."
"The licensing cost is about $50,000."
"Radware DefensePro is expensive when considering the issue we have and its limitations."
"It is expensive. I would rate it a seven out of ten for pricing."
"I didn't check pricing of other providers in depth but verified with two, and found Radware to be significantly cheaper compared to F5."
"You can't just stop auto-renew from your billing panel, the way you can with reputable businesses."
