Featured Reviews

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.
Nadeem Syed - PeerSpot reviewer
A comprehensive and advanced product that prevents DDoS attacks
Kaspersky DDoS Protection offers three layers of support. The first layer of support is from the reseller, the second from the distributor, and the third from Kaspersky itself. Kaspersky has two support options. If one of my clients to whom I have sold Kaspersky licenses is facing an issue, they have to register themselves and wait in queue for support. It can take around 24-72 hours. A client can buy support from Kaspersky directly for a whole year. This type of support is quick and good since they respond within an hour.
Tanuj-Garg - PeerSpot reviewer
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

"From what I've seen so far, there are no negatives to report as of yet"
"I rate its stability a ten out of ten."
"The solution offers the flexibility to control configuration rules."
"It is easier to configure and develop documentation to see how we have configured firewalls."
"The technical support is good."
"It's a great product because it's scalable, has great coverage, and is mature with good defenses against DDoS attacks."
"The solution is stable, and the DNS servers are simple to use."
"I get a lot of value from Cloudflare's API because it enables you to build a separate environment inside the solution. You can create a domain for performing test requests before you move to the production environment and connect various domains."
"It is a mature product and we have not faced any DDoS attack. The tool is a comprehensive and advanced product. The solution is compatible with third-party products."
"Provides good monitoring and has a user-friendly dashboard."
"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."
"A valuable feature is the speed of signature updates."
"Its functionality is very good."
"The most valuable feature is the ability to create signatures on-demand."
"It's very good at protecting users from DDoS attacks. It's the leader in this domain."
"A flexible affordable solution for defense against DDos attacks."
"This solution is extremely scalable and has the highest level throughput (100G) which complies with Telco deployment."
 

Cons

"Cloudflare does not have an on-premise solution. If they had different approaches they could be better suited to accommodate more customers, such as on-premise and hybrid deployments. For example, hybrid deployments would be useful where you could move the traffic from the enterprise to the cloud."
"One area of improvement is in the Access Rules. Hypothetically, if we wanted to block or challenge traffic outside of the United States, the only way to currently do that (as far as I know) is to enter every single country outside of the United States. That could be a labor intensive job. A solution could be to enable users to create a rule where traffic is only allowed within a certain country."
"We have noticed multiple instances where Cloudflare falsely indicates that our servers are down, even when there is no actual load on them. This makes it challenging for us to identify the exact issue."
"It would be helpful if the solution could continue evolving to compete with the other solutions on the market."
"An integrated SSO feature would be useful for Cloudflare DNS."
"It would be good if Cloudflare could have more servers for better traffic routing or an increase in the traffic routed. This is what I'd like to improve in Cloudflare."
"We are a product integrator and reseller, and we would like to have a better partner relationship, similar to a channel sales relationship. Sometimes we are on our own or get diverted by Cloudflare because they have direct sales, which competes with us and makes it difficult to build a relationship with this company since we want to be an MSP or a managed service provider for the solution."
"There could be more courses with engineers. I like e-learning, however, having a specialist in a classroom is more comfortable for me."
"Kaspersky DDoS Protection's cloud version does not support all the features of its on-prem version. The solution needs to improve its support since clients can face issues that hurt their network. They would need an immediate response."
"I had some trouble in the registration account prior to deployment, but it was fixed. They were not very fast or responsive, however. It took about one week to resolve the issue."
"Radware's management is very proactive, but Radware's lower-level staff is not proactive. You need to do a lot of follow-ups."
"Radware DefenseFlow should add new features and algorithms to make it efficient."
"We heavily relied on Radware's technical team to ensure the proper setup and configuration of VPN tunnels for cloud mitigation."
"I want to improve the blocking time; it should be within 10 seconds because 18 seconds allows multiple transactions in the financial industry."
"This solution may not cover all of the requirements in situations for which I am unfamiliar, and there is always room for improvement."
"Its documentation is not 100% clear, making it the weakest aspect of Radware. We have encountered some difficulties in understanding how to configure it correctly."
"I would like to see more focus on layer seven protection."
 

Pricing and Cost Advice

"A free version of the solution is available."
"So far I use free tier and happy with it. You can subscribe to business package if needed."
"We are using the free version."
"When you compare Cloudflare DNS to other solutions, such as Akamai, the price is reasonable."
"The tool is a premium product, so it is very expensive."
"It's a premium model. You can start at zero and work your way up to the enterprise model, which has a very high pricing level."
"There are no additional costs beyond the standard licensing fees."
"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."
"Kaspersky DDoS Protection's prices are average. Compared to other brands, prices are competitive. When you purchase many licenses, you get a heavy discount. However, the prices are not affordable."
"The product's pricing is a good value."
"The licensing cost is about $50,000."
"The pricing is okay, and I do not have any concerns about the price."
"It is not expensive. It is medium range. The pricing is good, as we recently renewed our licenses from Radware."
"I didn't check pricing of other providers in depth but verified with two, and found Radware to be significantly cheaper compared to F5."
"Radware DefensePro is expensive when considering the issue we have and its limitations."
"It is sort of middle-of-the-road for this type of solution."
"The pricing is based on the amount of network traffic and the number of packets being inspected."
