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

"It is a stable solution. I rate the stability a ten out of ten...I rate the scalability a ten out of ten."
"Using the CDN of Cloudflare improved the speed significantly, reducing the page loading times to appropriate levels."
"The overall performance of this solution is what makes it one of the best solutions on the market."
"I rate its stability a ten out of ten."
"It's a reasonably priced solution that meets customers' needs and it's not too difficult to deploy."
"The most valuable feature is the web application firewall."
"We're partners with Cloudflare; this solution is the best product and it does not charge you for any kind of attack on your traffic, only for good traffic, and it can mitigate up to 30 TBPS of DDoS attacks."
"DDoS protection is this product’s most valuable feature."
"Rate limiting is a good feature that protects from volumetric attacks."
"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 has positively impacted my organization by helping to obtain better solutions in less time and in a much more traceable way."
"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."
"Initially, we faced load time issues, but after deploying Fastly and optimizing our queries, we achieved a response time cut to less than 1 millisecond from an initial 3 to 4 seconds."
"The product helps our organization to access sites located in different regions quickly."
"Its initial setup process is straightforward."
"It is a stable solution."
"The UI is very intuitive."
"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."
"I enjoy engaging in discussions with colleagues possessing unique expertise. I leverage the three platforms—Azure, Google, and AWS extensively. This allows me to offer diverse solutions to customers, commonly referred to as a multi-cloud approach."
"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 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."
 

Cons

"Integration involving API with other products could be more user-friendly."
"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."
"I would like Cloudflare to offer a dedicated account manager for large enterprise clients like us."
"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."
"The reporting can definitely be improved to offer a lot more explanation on something that may have happened or has actually happened."
"DNS Management."
"For the services I am using, it is a bit expensive."
"We are a product integrator and reseller, and we would like to have a better partner relationship, similar to a channel sales relationship. Sometimes we are on our own or get diverted by Cloudflare because they have direct sales, which competes with us and makes it difficult to build a relationship with this company since we want to be an MSP or a managed service provider for the solution."
"What I don't like about Fastly is that they charge a heavy price."
"Support is not that great."
"Fastly can be improved in certain areas such as VCL, which is powerful but has a steep learning curve for normal users."
"It's not easy to start with Fastly if you don't have VCL knowledge, so it appears very complex at the beginning."
"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."
"The solution's pricing could be better."
"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."
"We are not getting quick responses from Fastly technical support engineers. Sometimes they depend on their D3 developers."
"I aim to enhance the reporting."
"Exploring shared access solutions with cloud accounts would be a beneficial choice."
"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."
"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."
"Azure is continuously improving its CDN but the documentation should be up-to-date."
"They should include configuration for cache rules."
"The response time of the support team must be improved."
