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.

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

"I rate its stability a ten out of ten."
"The DDoS protection is the most valuable aspect of the solution."
"The most valuable feature of Cloudflare DNS is security."
"The solution automatically detects and responds to certain types of traffic based on geolocation."
"I like Cloudflare's application gateway and DDoS protection."
"The simplicity of the overall dashboard makes it a great product for a user like me who has less understanding of the internet than a developer or other more technical people. It gives me peace of mind. I also love the easy customization of the Page Rules."
"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."
"Centralized, full-featured DNS."
"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."
"Rate limiting is a good feature that protects from volumetric attacks."
"The product helps our organization to access sites located in different regions quickly."
"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."
"Its initial setup process is straightforward."
"Compute@Edge features are valuable to me."
"Fastly uses configuration versioning, where you can deploy a new version in less than one minute."
"It is a stable solution."
"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."
"The fact that it just delivers what it is supposed to do is its most valuable feature...The initial setup is very straightforward."
"The UI is very intuitive."
"We use the product for faster content delivery with low latency."
"The most valuable feature of Windows Azure CDN is its effectiveness."
"The most valuable feature of the solution stems from the fact that one can access Windows Azure CDN from anywhere."
"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."
 

Cons

"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."
"Cloudflare could offer a better view or maybe dashboards of the main resources used in the client."
"The pricing could be improved."
"DNS Management."
"It would be good if Cloudflare could have more servers for better traffic routing or an increase in the traffic routed. This is what I'd like to improve in Cloudflare."
"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."
"Cloudflare could be improved by introducing a mid-tier pricing option."
"The documentation could improve for Cloudflare DNS."
"The solution's pricing could be better."
"The product should provide improved bot detection and management."
"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."
"Fastly's customer service area needs improvement."
"Support is not that great."
"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."
"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."
"Windows Azure CDN should lower its prices."
"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."
"Exploring shared access solutions with cloud accounts would be a beneficial choice."
"The response time of the support team must be improved."
"Azure is continuously improving its CDN but the documentation should be up-to-date."
"They should include configuration for cache rules."
"I believe Windows Azure CDN can improve monitoring and measuring overall end-user performance. Providing monitoring tools or agents that can be integrated into our pages would be highly beneficial. Setting up a custom domain with Windows Azure CDN involves proving domain ownership, which can take some time. The process is relatively straightforward if your DNS or domain registrar is already integrated with Microsoft. However, the verification process may be more time-consuming if you use a different service provider."
"I aim to enhance the reporting."
 

Pricing and Cost Advice

"We are using the free tier of the solution."
"Cloudflare's pricing is not much higher and is good for middle-level organizations."
"The price of the solution is expensive."
"The product's pricing is minimal compared to other products."
"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 cost primarily depends on the size of the organization."
"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."
"When you compare Cloudflare DNS to other solutions, such as Akamai, the price is reasonable."
"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 solution is cheaper than other products in the market."
"I've generally found Fastly to be very competitive in pricing, especially around Compute@Edge."
"It is an expensive solution."
"The pricing has been very competitive."
"The tool's pricing is cheap."
"It comes at a relatively affordable cost."
"The tool's pricing is cheap."
"The solution's price is above the medium range."
"The pricing is extremely high, almost 9 out of 10."
"The solution's price depends on how much traffic you have. So, it was okay for us. Payments are to be made on a monthly basis since one has to pay for what they used."
"On a scale from one to ten, where one is cheap, and ten is expensive, I rate the solution's pricing a five out of ten."
"I rate the price of Windows Azure CDN a six on a scale of one to ten, where one is cheap, and ten is high."
