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 is very straightforward."
"The most valuable feature is the web application firewall."
"When using services like Heroku, Cloudflare is very useful for CNAME flattening. I also use it for their end-to-end SSL with TLS authentication on nginx for securing servers."
"Because our website is blazing fast it improves our conversion rates."
"The initial setup is extremely easy but will require access to your Domain Name Servers."
"From what I've seen so far, there are no negatives to report as of yet"
"Cloudflare DNS is widely used, and it's good for websites. If we use Cloudflare DNS and update one record, it updates in their office instantly."
"The most valuable feature is its usability."
"It is a good solution, its vendor support is the most valuable, and it is simple and works well if you have Juniper MX routers."
"The DDoS protection features are valuable."
"I like the fact that the product provides a hybrid solution."
"It is a good solution. Its vendor support is the most valuable. It is simple and works well if you have Juniper MX routers."
"SmartWall devices occupy only one-fourth of the width of a rack unit, making them very easy to install."
"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."
"This is a hybrid solution."
"It is a very efficient and robust appliance."
"They have a hybrid model approach if a client wants to go that way."
"The initial setup is simple, the deployment should take no more than one or two days, and the support from Radware is very helpful."
"The intuitive user interface makes the entire process seamless and efficient."
"The solution offers a keen, tight service; it's very good at protecting us from DDoS attacks, very good at cleaning our pipeline when support routes traffic through, the product has been stable, the performance is pretty good, and the pricing is reasonable."
"It's very good at protecting users from DDoS attacks. It's the leader in this domain."
"Overall, I'm happy with this solution and what it has offered so far."
"The initial setup is easy."
"The product integrates well with Cisco."
 

Cons

"We had to do a lot of digging and back-and-forth with technical support for specific use cases, and it might be helpful to have more screencasts or screenshots for common situations."
"There might be helpful if there was some web application firewall feature."
"Latencies are always a problem."
"Although I think it's quite good, it doesn't provide me with all the features I would expect to have if I were using Imperva."
"For the free and Pro plans, Cloudflare could use a simple bot to provide information to users. This would improve support, especially for less advanced users who utilize the free components."
"The solution could use more analytics on the backend to give us more insights into everything. More reports would be helpful."
"Sometimes their more advanced caching tools can cause higher first-byte times and problems with JavaScript."
"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."
"It could use support in Spanish."
"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. 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 product must provide more Layer 7 capabilities."
"Lacks international presence."
"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 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."
"Juniper is known in our country, but it is not very popular."
"This product would be improved if ongoing live monitoring with dashboards were added."
"They should add artificial intelligence to the platform. It is currently missing the machine learning piece."
"Radware's management is very proactive, but Radware's lower-level staff is not proactive. You need to do a lot of follow-ups."
"I suggest improvements to the user interface to make it easier to use and to find the necessary data for analysis."
"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."
"This solution may not cover all of the requirements in situations for which I am unfamiliar, and there is always room for improvement."
"We would like to have seven-layer functionality."
"I would like to have more granular steps according to protected bandwidth, so the granularity should be better."
 

Pricing and Cost Advice

"The pricing depends on the usage, but the cheapest would be around 5,000 USD a month."
"That is one of the great features. I was able to access the majority of the features and services for free."
"The tool is a premium product, so it is very expensive."
"We are using the free tier of the solution."
"I give the price a five out of ten."
"A free version of the solution is available."
"There are no additional costs beyond the standard licensing fees."
"The cost primarily depends on the size of the organization."
"Its price is normal."
"The price of Corero is affordable."
"It is expensive. I would rate it a seven out of ten for pricing."
"The initial cost is over $100,000 for one appliance."
"The price varies by use case and there are monthly and annual licensing options. If you deploy on-premise, there is an annual license with the amount dependent on the throughput you need and which features you will be using - i.e. IPS, behavioral, etc."
"Radware DefensePro is a bit on the expensive side."
"The product's pricing is a good value."
"It is sort of middle-of-the-road for this type of solution."
"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."
