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.

The product is highly stable and has valuable features, but it must provide more Layer 7 capabilities

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 most valuable feature of Cloudflare DNS is security."
"The solution is very good at mitigating threats."
"New and innovative way to protect the client's data."
"Its ease of integration with Office 365 and the fact that it's a good product compared to what I had before"
"The most valuable features of the solution are performance and security."
"It is a stable solution. I rate the stability a ten out of ten...I rate the scalability a ten out of ten."
"I like Cloudflare's application gateway and DDoS protection."
"There are key things that are used for our enterprise customers, such as Lambda and DNS."
"The most valuable feature of Corero is its ability to handle smaller attacks in terms of the amount of volume and time. You can handle almost 100 perfect of the attacks locally."
"It is a good solution. Its vendor support is the most valuable. It is simple and works well if you have Juniper MX routers."
"This is a hybrid solution."
"The most important aspect, in general, is that the price is suitable for most clients."
"SmartWall devices occupy only one-fourth of the width of a rack unit, making them very easy to install."
"The DDoS protection features are valuable."
"It is an agnostic and transparent inline platform, which means that the maximum visibility of the symmetric and asymmetric traffic is available, even allowing bidirectional detection of the attack."
"The most valuable feature is the ability to create signatures on-demand."
"The most important part is that Radware DDoS integrates seamlessly and provides anomaly identification, real-time notifications, and security against DDoS attacks. It also helps us with multi-layer volumetric attacks. It shields us from global botnet threats."
"The key strength of Radware's Cloud DDoS Protection Service is its behavior engine, which uses anomaly detection to identify and stop DDoS attacks."
"Radware's support is first class."
"The DDoS protection that the solution provides is its most valuable feature."
"It offers valuable insights into ongoing and past attacks, aiding in post-incident analysis and continuous improvement of our cybersecurity strategy."
"They have a hybrid model approach if a client wants to go that way."
"Radware DDoS Protection Service has positively impacted my organization because we are more protected against attacks from the internet."
 

Cons

"The integration of LLMs on the dashboard is something that is needed in the tool."
"There could be more courses with engineers. I like e-learning, however, having a specialist in a classroom is more comfortable for me."
"There are some issues with the CDN services."
"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 timing aspect can lead to it being considered overpriced. This is a particular concern we have with Cloudflare, as they may struggle with accurately detecting the client."
"The solution could be more user-friendly."
"DNS Management."
"Technical support is not well developed. While there are good engineers, Cloudflare does not offer hands-on technical support to fix customer problems but rather a self-service model."
"The product must provide more Layer 7 capabilities."
"Juniper is known in our country, but it is not very popular. There is also not enough information about Corero. Our enterprise and financial sectors don't know about this solution. They need to provide more information and do more marketing for this solution in our country."
"Corero needs to improve its application DDoS prevention capabilities and user behavior detection features."
"It could use support in Spanish."
"Lacks international presence."
"The approach taken by Corero is to partner with other organizations in order to address volumetric attacks that cannot be handled by the hardware installed in the infrastructure. Corero does not have a solution for these attacks, so they are looking for partners to help them manage them. This approach is supplemented by local hardware, but the main focus is on the partnerships. It would be beneficial to have a more complete solution."
"We heavily relied on Radware's technical team to ensure the proper setup and configuration of VPN tunnels for cloud mitigation."
"Radware should focus on customization and integration, allowing routers and firewalls from other parties to integrate with the DDoS solution, enhancing security."
"Their Cyber Security Controller portal, including its GUI and dashboard, could be more intuitive so CXOs can easily understand them."
"It currently takes about 15 to 20 minutes for the process to complete, which should be minimized."
"The inability to access local technical support during our business hours poses a significant inconvenience."
"They need to increase the limit of devices that we can manage."
"There is room for improvement in the pricing; the product could be more affordable."
"I want to improve the blocking time; it should be within 10 seconds because 18 seconds allows multiple transactions in the financial industry."
 

Pricing and Cost Advice

"So far I use free tier and happy with it. You can subscribe to business package if needed."
"A free version of the solution is available."
"When you compare Cloudflare DNS to other solutions, such as Akamai, the price is reasonable."
"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."
"For Cloudflare, I recommend it heavily for small businesses with revenue under a couple of million dollars. Onboarding is easy, and they even have a free plan. This makes it simple for businesses in the $100,000-$500,000 range to try it out and see its value, allowing them to scale up their infrastructure as needed."
"Cloudflare's pricing is not much higher and is good for middle-level organizations."

"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."
"Radware's Cloud DDoS Protection Service stands out for its competitive pricing, making it a strong contender in our decision."
