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

"I didn’t have to pay anything for better website security and reduced server load."
"The solution offers the flexibility to control configuration rules."
"It's a great product because it's scalable, has great coverage, and is mature with good defenses against DDoS attacks."
"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 solution automatically detects and responds to certain types of traffic based on geolocation."
"Cloudflare is very straightforward."
"It is easier to configure and develop documentation to see how we have configured firewalls."
"It is very clear and the information is very useful."
"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."
"I like the fact that the product provides a hybrid solution."
"It is a very efficient and robust appliance."
"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."
"This is a hybrid solution."
"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."
"The most important aspect, in general, is that the price is suitable for most clients."
"The DDoS protection that the solution provides is its most valuable feature."
"Radware DDoS has positively impacted my organization by sorting unwanted traffic, specifically malicious traffic targeting the applications, and it has taken the burden off the perimeter firewall during incidents."
"The initial setup is easy."
"Data scrubbing and unmatched DDoS protection are valuable features."
"The most important thing for me right now in the Radware portfolio, is that Radware went to the cloud and has a flexible model based on virtual machines that can be delivered in our data center model, which could be delivered via the public cloud."
"A flexible affordable solution for defense against DDos attacks."
"The intuitive user interface makes the entire process seamless and efficient."
"The most valuable feature is the controller that determines when and how traffic can be moved to the cloud."
 

Cons

"We have noticed multiple instances where Cloudflare falsely indicates that our servers are down, even when there is no actual load on them. This makes it challenging for us to identify the exact issue."
"Integration involving API with other products could be more user-friendly."
"The tool needs to improve caching of servers. The product needs to include PFX certificate as well."
"However, what I still fail to understand is that why aren't they offering domains themselves."
"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."
"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."
"For the services I am using, it is a bit expensive."
"Access to the solution's dashboards is not intended for a service company. You are practically blind, and to validate a problem, you must view the customer's screen."
"It could use support in Spanish."
"Juniper is known in our country, but it is not very popular."
"Lacks international presence."
"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."
"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."
"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."
"To improve my ability to monitor security events, I would like Radware to strengthen its integration with SIEM for better logging capabilities."
"Radware DefenseFlow should add new features and algorithms to make it efficient."
"In terms of specific features missing in Radware DDoS, I would appreciate seeing an API Protector or similar capabilities that Akamai has."
"They should add artificial intelligence to the platform. It is currently missing the machine learning piece."
"I think Radware DDoS Protection Service could be improved by enhancing the network analytics features."
"They need to increase the limit of devices that we can manage (currently it is 100). I manage a huge network and I am forced to use two and this is very uncomfortable."
"Customization could be improved."
"The dashboard could be updated."
 

Pricing and Cost Advice

"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."
"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."
"The product's pricing is minimal compared to other products."
"The price is reasonable."
"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."
"It's a premium model. You can start at zero and work your way up to the enterprise model, which has a very high pricing level."
"A free version of the solution is available."
"Its price is normal."
"The price of Corero is affordable."
"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."
"Its pricing is competitive. The licensing model is also very competitive. It is customizable, so there is no issue at all. They have given us whatever we have asked in terms of the pricing model and SLA."
"It is sort of middle-of-the-road for this type of solution."
"The Radware DefensePro was bundled together with our security platform."
"It is not expensive. It is medium range. The pricing is good, as we recently renewed our licenses from Radware."
"Radware's switch to a pay-as-you-go model last year provides great flexibility."
"The price was well over six figures."
"Radware's Cloud DDoS Protection Service stands out for its competitive pricing, making it a strong contender in our decision."
