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.

Edge caching has transformed response times and delivers faster candidate data globally
Fastly can be improved in certain areas such as VCL, which is powerful but has a steep learning curve for normal users. A more user-friendly, UI-based configuration could simplify the experience, alongside better templates for common use cases and dashboard improvements, as the current dashboard feels complex for beginners, and pricing can be hard to predict for smaller companies. I chose 8 out of 10 because it has excellent performance and low latency delivery, making it suitable for larger applications, with strong Edge Caching and instant purging capabilities. However, VCL complexity and pricing predictability, especially for smaller companies, along with a user-friendly dashboard are areas impacting my score.

Our data is cached faster and sites load faster
We use the solution for hosting static web applications. We use it to cache images or files We mostly distribute images through the CDN. Earlier, we were directly caching from the server to CDN. Since we started using the solution, there has been a significant improvement in the response time.…

Quotes from Members

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

Pros

"Using the CDN of Cloudflare improved the speed significantly, reducing the page loading times to appropriate levels."
"I have not had a DDOS attack since, or at least not become unavailable due to DDOS which means my ROI is pretty good."
"It is very clear and the information is very useful."
"This solution has improved the security of our organization."
"It is easier to configure and develop documentation to see how we have configured firewalls."
"Cloudflare has positively impacted our organization by giving us flexibility to manage the DNS part, being quite fast, and allowing us to manage everything from a single dashboard, which is quite handy."
"The initial setup is extremely easy but will require access to your Domain Name Servers."
"The overall experience with Cloudflare is positive, with a rating of eight out of ten."
"Compute@Edge features are valuable to me."
"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."
"Fastly uses configuration versioning, where you can deploy a new version in less than one minute."
"The product helps our organization to access sites located in different regions quickly."
"Rate limiting is a good feature that protects from volumetric attacks."
"Its initial setup process is straightforward."
"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."
"The most valuable feature of the solution stems from the fact that one can access Windows Azure CDN from anywhere."
"The geolocation feature is very important because many colleagues travel worldwide and need to access information from anywhere. The product has improved security."
"The most valuable feature of Windows Azure CDN is its effectiveness."
"I like that CDN offers a routing feature."
"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."
"It is a stable solution."
"The fact that it just delivers what it is supposed to do is its most valuable feature...The initial setup is very straightforward."
"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."
 

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."
"The documentation could improve for Cloudflare DNS."
"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 support needs to be accessible from more places, a wider area of coverage."
"Latencies are always a problem."
"Cloudflare could offer a better view or maybe dashboards of the main resources used in the client."
"The solution could be more user-friendly."
"I would like to not need a separate server for non-www redirection under the CNAME setup option."
"I think Fastly could improve by improving the documentation and having some code examples so that it is easier for developers, since at the beginning it becomes a bit complicated."
"What I don't like about Fastly is that they charge a heavy price."
"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."
"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."
"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."
"Another downside of Fastly is that when we wanted to migrate our API domains, it's lacking the WebSocket protocol."
"Fastly can be improved in certain areas such as VCL, which is powerful but has a steep learning curve for normal users."
"We have experienced issues with switch connectivity."
"The response time of the support team must be improved."
"They should include configuration for cache rules."
"There were a few bugs that were very disappointing. So, that is a part of the reason why we started using Fastly."
"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."
"The solution’s pricing could be improved."
"Windows Azure CDN should lower its prices."
"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."
 

Pricing and Cost Advice

"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."
"When you compare Cloudflare DNS to other solutions, such as Akamai, the price is reasonable."
"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."
"There are no additional costs beyond the standard licensing fees."
"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."
"The pricing for the service is reasonable, neither excessively cheap nor prohibitively expensive. It aligns well with the value of their solution."
"We are using the free tier of the solution."
"That is one of the great features. I was able to access the majority of the features and services for free."
"Fastly is less expensive than one of its competitors."
"The pricing has been very competitive."
"I've generally found Fastly to be very competitive in pricing, especially around Compute@Edge."
"In my opinion, Fastly is priced competitively."
"The solution is cheaper than other products in the market."
"You need to pay a premium price for the tool."
"It is an expensive solution."
"It comes at a relatively affordable cost."
"The tool's pricing is cheap."
"The pricing is extremely high, almost 9 out of 10."
"The solution's price is above the medium range."
"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."
"The tool's pricing is cheap."
"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."
