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

"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."
"Using the CDN of Cloudflare improved the speed significantly, reducing the page loading times to appropriate levels."
"The UI is good."
"The most valuable feature of Cloudflare DNS is its global reach and it is always evolving."
"From what I've seen so far, there are no negatives to report as of yet"
"The solution is stable, and the DNS servers are simple to use."
"Centralized, full-featured DNS."
"The most valuable feature of Cloudflare DNS is security."
"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."
"The product helps our organization to access sites located in different regions quickly."
"Compute@Edge features are valuable to me."
"Rate limiting is a good feature that protects from volumetric attacks."
"Its initial setup process is straightforward."
"Fastly uses configuration versioning, where you can deploy a new version in less than one minute."
"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."
"Fastly provides CDN, WAF, image optimization, and IP restriction."
"Radware DDoS is very effective in mitigating distributed denial-of-service attacks, the solution is very mature, and since Radware DDoS can detect attacks within 18 seconds, it really helps the organization against those types of attacks."
"Radware DDoS is very useful for us in protecting from many attacks, particularly flood attacks and SYN flood attacks, which we deal with in the banking environment."
"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 product integrates well with Cisco."
"The most valuable feature is the controller that determines when and how traffic can be moved to the cloud."
"Radware DDoS Protection Service has positively impacted my organization because we are more protected against attacks from the internet."
"Radware DefensePro's most valuable feature lies in its ability to mitigate non-traffic attacks."
"It ensures both security and performance. It achieves this by learning behavior patterns and providing protection without blocking normal traffic."
 

Cons

"The Cloudflare load balancing capability hasn't really helped in enhancing my website's uptime and resiliency because we don't really get that much traffic; it's mostly remote users, and web hosting is done by a web hosting service."
"We experienced some downtime in the fall of 2013, causing us to switch to Incapsula."
"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."
"Cloudflare doesn't have a reverse lookup. We can only do a DNS lookup to get the IP address from the hostname. It doesn't work if you want to look up the hostname from an IPA address."
"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."
"Cloudflare should add more documentation and pricing to the cloud version."
"I have found CloudFlare's support to be unresponsive at times, and not very helpful with providing technical details for issues that we have reported over the years."
"There should be a specific price list for enterprise-level customers."
"We are not getting quick responses from Fastly technical support engineers. Sometimes they depend on their D3 developers."
"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."
"What I don't like about Fastly is that they charge a heavy price."
"Fastly's customer service area needs improvement."
"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 solution's pricing could be better."
"The product should provide improved bot detection and management."
"Support is not that great."
"They should add artificial intelligence to the platform. It is currently missing the machine learning piece."
"We would like to have seven-layer functionality."
"The solution is a little more pricey than other options on the market."
"There's room for improvement in the clarity of the feedback provided by the command service in the CLI."
"I had some trouble in the registration account prior to deployment, but it was fixed. They were not very fast or responsive, however. It took about one week to resolve the issue."
"This solution may not cover all of the requirements in situations for which I am unfamiliar, and there is always room for improvement."
"It could incorporate more intelligence for reacting with web site visitors."
"I would like to see more focus on layer seven protection."
 

Pricing and Cost Advice

"There are no additional costs beyond the standard licensing fees."
"The product's pricing is cheap."
"When you compare Cloudflare DNS to other solutions, such as Akamai, the price is reasonable."
"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."
"The price is reasonable."
"The cost primarily depends on the size of the organization."
"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."
"It is an expensive solution."
"The solution is cheaper than other products in the market."
"You need to pay a premium price for the tool."
"I've generally found Fastly to be very competitive in pricing, especially around Compute@Edge."
"The pricing has been very competitive."
"In my opinion, Fastly is priced competitively."
"Fastly is less expensive than one of its competitors."
"Radware DefensePro is expensive when considering the issue we have and its limitations."
"The initial cost is over $100,000 for one appliance."
"The Radware DefensePro was bundled together with our security platform."
"Radware's Cloud DDoS Protection Service stands out for its competitive pricing, making it a strong contender in our decision."
"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."
"The licensing cost is about $50,000."
"The product's pricing is a good value."
"I didn't check pricing of other providers in depth but verified with two, and found Radware to be significantly cheaper compared to F5."
