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

"Cloudflare has made management of my website much easier by combining various functions in one platform without compromising quality."
"Cloudflare's DNS services deliver the best performance in terms of speed and reliability."
"Cloudflare offers CDN and DDoS protection. We have the front end, API, and database in how you structure applications."
"CloudFlare's caching brings the load speed down from 4.32 seconds to 2.45 seconds."
"Cloudflare is a security SaaS provider that provides security and protects us from any application layer attack."
"The solution is stable, and the DNS servers are simple to use."
"The initial setup is extremely easy but will require access to your Domain Name Servers."
"The solution is a great fit for customers who want unlimited bandwidth."
"This is a hybrid solution."
"I like the fact that the product provides a hybrid solution."
"The DDoS protection features are valuable."
"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 most important aspect, in general, is that the price is suitable for most clients."
"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."
"It is a very efficient and robust appliance."
"It has not gone down for a quite long time. It's working fine."
"It has kept us up and operational on a day-to-day basis, without being interrupted by an attack from outside sources."
"This solution is extremely scalable and has the highest level throughput (100G) which complies with Telco deployment."
"We have been able to integrate the solution into our network without it affecting the network overall."
"It offers valuable insights into ongoing and past attacks, aiding in post-incident analysis and continuous improvement of our cybersecurity strategy."
"In terms of the environment that I work in, the SSL, DNS, and HTTP are all valuable features."
"Radware Cloud DDoS Protection Service goes beyond the essential Layer Three and Layer Four protection, which are practically mandatory these days."
"It is very easy to deploy and I did it myself."
 

Cons

"I would like to not need a separate server for non-www redirection under the CNAME setup option."
"At the end, it is worth than giving your house keys to the NSA."
"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."
"Perhaps I would ask that they improve the Free plan and allow us to use it with any TLD (certain ones are not allowed)."
"Yes, there were a few times when some of their CDN nodes would fail, creating serious speed issues with the site without any warning or notification from their side."
"The installation was complex until I learned what I had to learn."
"We're facing challenges due to an upgrade in the machine learning model. The problem arises from some users abusing the APIs, resulting in an influx of suspicious traffic. Cloudflare's learning model mistakenly identifies this traffic as human. Consequently, it assigns it a higher trust score, akin to legitimate human traffic, causing complications in our architecture. Previously, such traffic would have been categorized as suspicious, enabling us to apply appropriate blocking rules. However, we encounter difficulties distinguishing between genuine and suspicious traffic with the new categorization. Despite these challenges, overall, Cloudflare remains the preferred solution compared to Azure, AWS CloudFront, and Google Cloud Armor."
"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."
"Lacks international presence."
"Corero needs to improve its application DDoS prevention capabilities and user behavior detection features."
"Juniper is known in our country, but it is not very popular."
"It could use support in Spanish."
"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."
"I'd like to see an increase in Corero's international team. Our clients are generally companies with an international presence and Corero is not represented in all the countries where our clients have 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."
"The quality of first-level support might not be so high at times, especially if it is a technical team that is working or managing the DDoS environment as a client."
"They didn't listen to what we were asking for and what we needed."
"The inability to access local technical support during our business hours poses a significant inconvenience."
"Radware's management is very proactive, but Radware's lower-level staff is not proactive. You need to do a lot of follow-ups."
"During our last DDoS attack in February, we were setting up the system too strict. After some time, our protection started to kill our traffic."
"I would like to see more graphics within the dashboard. Right now, you are required to buy tools in order to have a graphical representation for your monitoring."
"The speed and quality of Radware DDoS's support should be improved."
"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."

"The solution is expensive when compared to other products but offers unlimited bandwidth."
"The price of the solution is expensive."
"There are no additional costs beyond the standard licensing fees."
"The product's pricing is cheap."
"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."
