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.

Optimized ecommerce performance and improved access control through image handling and IP filtering
I believe that Fastly should provide guidelines for their WAF blocking rules. It should be public what the rules are that are blocking their contents. I believe Fastly should provide regional IP addresses instead of POP IPs. Fastly should provide features similar to Cloudflare regarding a block list. Additionally, a POP address should be there with a wide range of IP addresses provided, public static IP addresses, so customers can integrate egress IPs. Fastly should provide WebP image processing on the backend instead of on the fly. It would be a very useful feature to avoid unnecessary time for browser to browser and local cookies. I believe that Fastly service has a few gaps. We are not getting quick responses from Fastly technical support engineers. Sometimes they depend on their D3 developers. There should be transparency.

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

"We're using dynamic components to build flexible pages to create and manage Git merge requests for code and reviews."
"The solution offers the flexibility to control configuration rules."
"The technical support is good."
"The most valuable feature of Cloudflare DNS is security."
"The aggressive caching and DDOS mitigation are the most valuable features offered by Cloudflare."
"The solution is very good at mitigating threats."
"DDoS attacks target unprotected machines. Cloudflare detects and stops these attacks using internal systems. It identifies incoming DDoS attacks, issuing challenges or blocking them immediately."
"CloudFlare has positively improved my site's speed, performance and security."
"Support is good; the product works as advertised. We have a Slack connection with them. So we can basically ask for help, live, engage, and ring when they respond. Very quickly."
"Compute@Edge features are valuable to me."
"Fastly uses configuration versioning, where you can deploy a new version in less than one minute."
"Fastly provides CDN, WAF, image optimization, and IP restriction."
"Its initial setup process is straightforward."
"The product helps our organization to access sites located in different regions quickly."
"The product's initial setup phase is straightforward."
"Fastly combines both the CDN side and the Signal Sciences next-generation WAF, which is closely integrated with the CDN, allowing us to use both products seamlessly."
"It ensures both security and performance. It achieves this by learning behavior patterns and providing protection without blocking normal traffic."
"Radware DefensePro is one of the best solutions for on-premise protection."
"SSL-based mitigation from DDoS attacks is good from their side. They are capable of preventing SSL-based attacks with certifications and everything loaded onto them."
"The dashboard is the best part, and there is also the ease of operations."
"This solution is extremely scalable and has the highest level throughput (100G) which complies with Telco deployment."
"A valuable feature is the speed of signature updates."
"The DDoS protection that the solution provides is its most valuable feature."
"Radware DDoS is the best tool, as it protects our applications just as we intended it to."
 

Cons

"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."
"The product needs to improve its automation."
"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."
"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."
"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."
"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."
"Sometimes their more advanced caching tools can cause higher first-byte times and problems with JavaScript."
"The reporting can definitely be improved to offer a lot more explanation on something that may have happened or has actually happened."
"It is missing a "staging" platform to deploy a test configuration with all of the real settings, which would allow us to properly test before putting it into production."
"The product should provide improved bot detection and management."
"Fastly's customer service area needs improvement."
"We are not getting quick responses from Fastly technical support engineers. Sometimes they depend on their D3 developers."
"Support is not that great."
"Stronger analytics would be helpful, like showing configurations that haven't served a certain amount of traffic in a while. With many properties, things can get lost track of - duplicates or unused configurations not properly decommissioned."
"The solution's pricing could be better."
"What I don't like about Fastly is that they charge a heavy price."
"I would like to see better implementation of a zero-day attack implementation strategy with self-mitigation."
"Its documentation is not 100% clear, making it the weakest aspect of Radware. We have encountered some difficulties in understanding how to configure it correctly."
"I would like to see more graphics within the dashboard. Right now, you are required to buy tools in order to have graphical representation for your monitoring."
"There is room for improvement in the pricing; the product could be more affordable."
"We would like to have seven-layer functionality."
"They need to increase the limit of devices that we can manage."
"I think Radware DDoS Protection Service could be improved by enhancing the network analytics features."
"The solution is a little more pricey than other options on the market."
 

Pricing and Cost Advice

"The pricing depends on the usage, but the cheapest would be around 5,000 USD a month."
"The product's pricing is minimal compared to other products."
"I give the price a five out of ten."
"That is one of the great features. I was able to access the majority of the features and services for free."
"The pricing for the service is reasonable, neither excessively cheap nor prohibitively expensive. It aligns well with the value of their solution."
"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."
"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."
"We don't have any issues with the price."
"I've generally found Fastly to be very competitive in pricing, especially around Compute@Edge."
"Fastly is less expensive than one of its competitors."
"You need to pay a premium price for the tool."
"In my opinion, Fastly is priced competitively."
"The pricing has been very competitive."
"The solution is cheaper than other products in the market."
"It is an expensive solution."
"Licensing of Radware is quite simple and straightforward, while Arbor DDos is a bit complicated."
"The pricing is okay, and I do not have any concerns about the price."
"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."
"The initial cost is over $100,000 for one appliance."
"Radware's switch to a pay-as-you-go model last year provides great flexibility."
"It is sort of middle-of-the-road for this type of solution."
"It is not expensive. It is medium range. The pricing is good, as we recently renewed our licenses from Radware."
"Radware's Cloud DDoS Protection Service stands out for its competitive pricing, making it a strong contender in our decision."
