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

"The initial setup is simple, the deployment should take no more than one or two days, and the support from Radware is very helpful."
"With Radware, there's a lot more granular control of what DDoS you're looking at in terms of DDoS visibility and protection."
"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."
"Radware DDoS has positively impacted our organization by ensuring we have no longer had service disruptions due to attacks of that kind, even though there have been frequent ones over time."
"Radware DDoS has positively impacted my organization by improving our security."
"It's very good at protecting users from DDoS attacks. It's the leader in this domain."
"The best thing about Radware DDoS for me is that the solution is very accurate, the information and the different types of graphics and data are very important, and it is easy to operate and to understand the solution in my case."
"I would recommend Radware DDoS to other users because in security, there are many layers of protection, and this is one of the most exposed regarding the internet."
"It seems to provide a bit of useful information on website health."
"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."
 

Cons

"There needs to be more reporting."
"They didn't listen to what we were asking for and what we needed."
"The speed and quality of Radware DDoS's support should be improved."
"Multiple times errors and issues show that legitimate traffic can be dropped, as the system is not understanding the particular customer's ports."
"I want to improve the blocking time; it should be within 10 seconds because 18 seconds allows multiple transactions in the financial industry."
"The rise of generative AI and machine learning in cyberattacks demands more advanced defense strategies."
"Last time we faced an issue with a version upgrade, and we faced extensive troubleshooting with one to two months wasted in the troubleshooting process."
"I suggest improvements to the user interface to make it easier to use and to find the necessary data for analysis."
"Sitelock may perform a useful service, but be wary of giving them your credit card information."
 

Pricing and Cost Advice

"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."
"Licensing of Radware is quite simple and straightforward, while Arbor DDos is a bit complicated."
"The initial cost is over $100,000 for one appliance."
"Radware DefensePro is expensive when considering the issue we have and its limitations."
"I didn't check pricing of other providers in depth but verified with two, and found Radware to be significantly cheaper compared to F5."
"The product's pricing is a good value."
"The pricing is okay, and I do not have any concerns about the price."
"The cost for maintenance is cheaper because the majority of the deployments using the solution are in areas where cost of maintenance is also lower."
"You can't just stop auto-renew from your billing panel, the way you can with reputable businesses."
