Advanced protection has secured critical web workloads and provides clear traffic visibility

From a security perspective, there remains a security loophole, as some browsers in the market can bypass the Turnstile solution, which requires approximately 40 seconds to do so. From a performance perspective, this is acceptable. We also tried Google reCAPTCHA, and that can also be bypassed. From a security perspective, I would say neither solution is completely secured. Regarding uptime, we have faced a couple of incidents due to Cloudflare in recent years, so I cannot say we receive 100% uptime for our region. We sometimes face challenges, including downtime and other issues. As a result, we are not receiving 100% uptime from Cloudflare's solution. Since most of our customers are in this region, we need alternatives. We need something more competitive than Cloudflare. Unfortunately, in Bangladesh, Cloudflare has three points of presence already, and we cannot find any other solution provider in Bangladesh as an alternative, which presents another challenge. Competitor solutions have more attack signatures, which ensure better security compared to Cloudflare's predefined configurations. Customers do not have options to modify any configuration parameters in Cloudflare, whereas other competitor solutions, such as F5 Distributed Cloud, allow customers to tune configurations according to their requirements. Cloudflare could improve in this area. Additionally, regarding visibility, Cloudflare has static visibility, but they could adopt dynamic graph features for their customers.

Effective network and DDoS protection with suitable pricing

I use Corero for network DDoS protection projects. It is particularly effective in providing protection against network DDoS attacks I find Corero to be good, especially in a wide area. It does not have application filtering or application DDoS prevention, but for network DDoS projects, it is…

Advanced protection has optimized web and API performance while reducing infrastructure costs

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.

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 the solution is external DNS. It is also very secure. They have their own main server and once you configure it, the product takes care of everything. There are no issues in resolving IPs and low latency is also present."

"The most valuable feature is the web application firewall."

"Cloudflare is a security SaaS provider that provides security and protects us from any application layer attack."

"The most valuable feature of Cloudflare is the GUI. You are able to control the solution very well through the interface. There is a lot of functionality that is embedded in the service."

"I like Cloudflare's application gateway and DDoS protection."

"Cloudflare has many features."

"The most valuable feature of Cloudflare is that it has a free version. They give us the free version with the anti-DDoS features and also the load balancing solution."

"We're using dynamic components to build flexible pages to create and manage Git merge requests for code and reviews."

More Cloudflare pros

"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 important aspect, in general, is that the price is suitable for most clients."

"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 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."

"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 has kept us up and operational on a day-to-day basis, without being interrupted by an attack from outside sources."

"All of our traffic has to pass through the appliance, so we can very quickly mitigate the attack. This is a very valuable feature. On top of that, it's not only volumetric attack protection that the solution offers, but also layer 7 attack protection as well."

"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."

"They have a hybrid model approach if a client wants to go that way."

"Radware Cloud DDoS Protection Service goes beyond the essential Layer Three and Layer Four protection, which are practically mandatory these days."

"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 reporting is very good and provides us with a comprehensive description of where attacks are emanating from."

"The initial setup is easy."

More Radware DDoS pros

Cons

"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."

"There could be more courses with engineers. I like e-learning, however, having a specialist in a classroom is more comfortable for me."

"It should have easier documentation for the configuration. It's very technical and people who aren't technical should also be able to do the configuration."

"Support response time could be improved."

"It would be beneficial for us if Cloudflare could offer a scrubbing solution. This would involve taking a snapshot of my website and keeping it live during a DDoS attack, ensuring uninterrupted service for our users. DDoS attacks are typically short in duration, and having Cloudflare maintain the site's availability from its secure network would enhance the overall user experience. I would appreciate it if Cloudflare could consider implementing this feature. Many organizations already utilize similar capabilities in their CDN platforms, where a static snapshot of the web page is displayed during DDoS attacks. In terms of features, Cloudflare needs to enhance its resilience and stay more focused on adopting new technologies. For instance, solutions like F5 XC Box, Access Solution, and Distributed Cloud Solution have impressive features, and Cloudflare should strive to match and exceed those capabilities. There's a need for improvement in areas like AI-based DDoS attacks and Layer 7 WAF features. Cloudflare should prioritize enhancements in areas such as behavioral DDoS and protection against SQL injection attacks, considering the prevalent trend of public exposure to the internet for business reasons. Overall, Cloudflare needs to invest more in advancing its feature set."

"The product needs to improve its automation."

"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."

"There should be a specific price list for enterprise-level customers."

More Cloudflare cons

"It could use support in Spanish."

"Corero needs to improve its application DDoS prevention capabilities and user behavior detection features."

"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."

"Lacks international presence."

"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."

"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."

"They need to increase the limit of devices that we can manage."

"I believe Radware DDoS could be improved for cloud deployments with more granular controls that could provide valuable gains for the company, especially by verifying whether the client is genuine or not with additional metrics."

"The speed and quality of Radware DDoS's support should be improved."

"The APSolute Vision feature needs improvement."

"Right now, we have DefensePro 6. The only complaint I have is that SSL inspection, when activated, consumes a lot of resources on the machine. We are currently reviewing a possible change to DefensePro X, the new version, which has a separate module with its processors."

"We would like to have seven-layer functionality."

"I suggest improvements to the user interface to make it easier to use and to find the necessary data for analysis."

More Radware DDoS cons

Pricing and Cost Advice

"The product's pricing is cheap."

"A free version of the solution is available."

"The product's pricing is minimal compared to other products."

"Cloudflare's pricing is not much higher and is good for middle-level organizations."

"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."

"When you compare Cloudflare DNS to other solutions, such as Akamai, the price is reasonable."

"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."

More Cloudflare pricing and cost advice

"Its price is normal."

"The price of Corero is affordable."

"Licensing of Radware is quite simple and straightforward, while Arbor DDos is a bit complicated."

"The NetFlow security could be improved too."

"The licensing cost is about $50,000."

"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 Cloud DDoS is very expensive."

"It is expensive. I would rate it a seven out of ten for pricing."

"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."
