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.
Nick Wilsdon - PeerSpot reviewer
An easily scalable and stable product that provides exceptional support
The product should provide improved bot detection and management. The product should also provide support for code management. Everybody working in CDN is currently looking for ways to better manage code deployment with various authorization levels and synchronization with our lower environments. Matching up what's happening in CDN with what's happening on the origin regarding testing would always be useful.
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

"The overall experience with Cloudflare is positive, with a rating of eight out of ten."
"It is easier to configure and develop documentation to see how we have configured firewalls."
"The technical support is good."
"Cloudflare is a security SaaS provider that provides security and protects us from any application layer attack."
"Smaller businesses have seen great ROI due to the low investment and strong performance."
"Its most significant benefit to date is the speed with which it refreshes DNS records on the internet once you change it. If you are changing a website or registering a new record, it is very quick."
"DDoS attacks target unprotected machines. Cloudflare detects and stops these attacks using internal systems. It identifies incoming DDoS attacks, issuing challenges or blocking them immediately."
"Cloudflare allows us to self-host services such as Rocket.Chat and Node-RED, in high-availability mode, thanks to round robin DNS which allows us to share one hostname between our two locations."
"Compute@Edge features are valuable to me."
"Support is good; the product works as advertised. We have a Slack connection with them. So we can basically ask for help, live, engage, and ring when they respond. Very quickly."
"The product's initial setup phase is straightforward."
"Fastly uses configuration versioning, where you can deploy a new version in less than one minute."
"Rate limiting is a good feature that protects from volumetric attacks."
"The product helps our organization to access sites located in different regions quickly."
"Its initial setup process is straightforward."
"Radware Cloud DDoS Protection Service goes beyond the essential Layer Three and Layer Four protection, which are practically mandatory these days."
"The DDoS protection that the solution provides is its most valuable feature."
"DDoS Protection Service provides excellent defense in the cloud, and the implementation and migration are very straightforward."
"A flexible affordable solution for defense against DDos attacks."
"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."
"Radware's support is first class."
"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."
"The initial setup is easy."
 

Cons

"Support response time could be improved."
"There could be more courses with engineers. I like e-learning, however, having a specialist in a classroom is more comfortable for me."
"Cloudflare's free plan is limited to 5,000 records for their free plan. They should increase that. For example, if I create a domain called abc.com and a subdomain called a.abc.com, my record count will be two. I can make a maximum of 5,000 subdomains. However, if we use our own DNS hosted on another provider, there is no limit. Their free plan also lacks name server customization."
"The documentation could improve for Cloudflare DNS."
"It should confirm audit findings of the assigned area with auditees to ensure that the audit conclusions are based on an accurate understanding of the issues."
"I would like Cloudflare to offer a dedicated account manager for large enterprise clients like us."
"The product needs to improve its automation."
"For large enterprises, the pricing is okay. However, the enterprise price for small projects is a bit high. A mid-tier pricing option would be beneficial."
"Fastly's customer service area needs improvement."
"The product should provide improved bot detection and management."
"Stronger analytics would be helpful, like showing configurations that haven't served a certain amount of traffic in a while. With many properties, things can get lost track of - duplicates or unused configurations not properly decommissioned."
"It is missing a "staging" platform to deploy a test configuration with all of the real settings, which would allow us to properly test before putting it into production."
"The solution's pricing could be better."
"Support is not that great."
"What I don't like about Fastly is that they charge a heavy price."
"Radware DefenseFlow should add new features and algorithms to make it efficient."
"Radware's management is very proactive, but Radware's lower-level staff is not proactive. You need to do a lot of follow-ups."
"They need to increase the limit of devices that we can manage."
"It would be ideal if they could expand protocol support to cover emerging communication standards and ensure comprehensive protection against diverse attack vectors."
"The APSolute Vision feature needs improvement."
"Customization could be improved."
"The inability to access local technical support during our business hours poses a significant inconvenience."
"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."
 

Pricing and Cost Advice

"We are using the free tier of the solution."
"The pricing depends on the usage, but the cheapest would be around 5,000 USD a month."
"I give the price a five out of ten."
"The price of the solution is expensive."
"I think the pricing is competitive. I think as far as licensing is concerned it's pretty straightforward because it's based on domain. It's just that sometimes domains could be tricky with some customers."
"I believe their performance has improved, but I'd like to refrain from discussing the pricing aspect related to the cloud. The pricing, in my opinion, could be simplified, and I think they should consider reevaluating the pricing for support, as it can be quite high. At times, this cost can make it challenging to choose CARFAGuard or opt for the support."
"The solution has many features but there are ones that you need to pay for. Sometimes you have to find out which is available for free and which you have to pay for."
"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."
"The pricing has been very competitive."
"It is an expensive solution."
"Fastly is less expensive than one of its competitors."
"The solution is cheaper than other products in the market."
"In my opinion, Fastly is priced competitively."
"I've generally found Fastly to be very competitive in pricing, especially around Compute@Edge."
"You need to pay a premium price for the tool."
"It is not expensive. It is medium range. The pricing is good, as we recently renewed our licenses from Radware."
"Licensing of Radware is quite simple and straightforward, while Arbor DDos is a bit complicated."
"It is sort of middle-of-the-road for this type of solution."
"The price was well over six figures."
"Radware DefensePro is expensive when considering the issue we have and its limitations."
"When compared with other solutions, my end user is satisfied with the costs and believes that Radware Cloud DDoS Protection Service is worth the price paid."
"The licensing cost is about $50,000."
"I didn't check pricing of other providers in depth but verified with two, and found Radware to be significantly cheaper compared to F5."
