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.

Pre Sales at a computer software company with 51-200 employees
Has provided exceptional performance for handling high web traffic
In my opinion, Windows Azure CDN is one of the best CDNs. We tried to replace it and made a business case to check other options such as Cloudflare, and we are using Cloudflare and tried Akamai, wanting to explore alternatives from OCI. One of the best features of Windows Azure CDN is that it has integrated WAF; it is not only CDN alone and it is a very smart and capable WAF. Windows Azure CDN is easily integrated with Azure services such as Azure Storage and Azure Web Apps, and sometimes we are using just Azure Front Door while the back end and database will be on OCI. The impact of Windows Azure CDN's dynamic content acceleration on our application performance is very significant. For one of our clients, we could not use anything other than Azure Front Door.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"In my opinion, CloudFlare is one of the best CDN networks I have ever used."
"The overall experience with Cloudflare is positive, with a rating of eight out of ten."
"I have used it to bring enterprise-grade features to my small business clients at low or no cost."
"Cloudflare is very straightforward."
"Smaller businesses have seen great ROI due to the low investment and strong performance."
"Cloudflare improves performance on my websites and is a great partner for cloud infrastructure for anyone who wants to use the security service and other features."
"Cloudflare makes it easier for me to handle and set up DNS for multiple users and multiple clients, and basically go in and access their account, make the changes they need, and it's a one-stop shop."
"Its most significant benefit to date is the speed with which it refreshes DNS records on the internet once you change it. If you are changing a website or registering a new record, it is very quick."
"The product's initial setup phase is straightforward."
"Fastly uses configuration versioning, where you can deploy a new version in less than one minute."
"Its initial setup process is straightforward."
"Compute@Edge features are valuable to me."
"The product helps our organization to access sites located in different regions quickly."
"Rate limiting is a good feature that protects from volumetric attacks."
"In summary, this solution is easy to manage, quick to deploy, and all of my customers are happy."
"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."
"One of the tool's best features is its ability to handle edge cases. For instance, we encountered a situation where we needed to remove certain files from public access. The solution offered a purge feature that allowed us to remove these files. This feature ensured that the files were deleted from all edge servers. Subsequently, we were able to upload new versions of the files."
"I like that CDN offers a routing feature."
"We use the product for faster content delivery with low latency."
"The most valuable feature of the solution stems from the fact that one can access Windows Azure CDN from anywhere."
"One of the best features of Windows Azure CDN is that it has integrated WAF; it is not only CDN alone and it is a very smart and capable WAF."
"The most valuable feature of Windows Azure CDN is its effectiveness."
"One of the most valuable aspects is the capability to store extensive datasets and objects in the cloud, enabling their download through shared access signatures."
"The UI is very intuitive."
 

Cons

"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."
"Latencies are always a problem."
"There might be helpful if there was some web application firewall feature."
"It should be easier to collect the logs with companies like Sumo. However, based on my discussions with the salespeople, I understand that's how they make their money. With the enterprise product, they want people doing those kinds of enterprise features to do the logging. They want them to pay a lot of money, and that's where I have an issue with them. That should be a default. You should be able to get the log no matter what. The logging should be universal."
"Latencies are always a problem."
"Cloudflare could be improved by introducing a mid-tier pricing option."
"One area of improvement is in the Access Rules. Hypothetically, if we wanted to block or challenge traffic outside of the United States, the only way to currently do that (as far as I know) is to enter every single country outside of the United States."
"DNS Management."
"The solution's pricing could be better."
"Fastly's customer service area needs improvement."
"What I don't like about Fastly is that they charge a heavy price."
"We are not getting quick responses from Fastly technical support engineers. Sometimes they depend on their D3 developers."
"The product should provide improved bot detection and management."
"Support is not that great."
"It's not easy to start with Fastly if you don't have VCL knowledge, so it appears very complex at the beginning."
"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."
"They should include configuration for cache rules."
"The response time of the support team must be improved."
"Exploring shared access solutions with cloud accounts would be a beneficial choice."
"The high price of Windows Azure CDN is an area of concern where improvements can be made."
"Azure is continuously improving its CDN but the documentation should be up-to-date."
"I aim to enhance the reporting."
"It is not a weakness of Windows Azure CDN; rather, it is the fact that it is outside Saudi Arabia, leading to some regulation issues."
"Windows Azure CDN should lower its prices."

"Cloudflare's pricing is not much higher and is good for middle-level organizations."

"The solution's price is above the medium range."

"The tool's pricing is cheap."
