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

"The attacker won't have details since my public IP is anonymous. It offers us good privacy."
"If someone is looking for a secure and optimized wrapper over an open website, I would suggest CloudFlare services."
"Because our website is blazing fast it improves our conversion rates."
"It is a fast and secure DNS."
"The most valuable feature of Cloudflare DNS is security."
"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."
"The overall performance of this solution is what makes it one of the best solutions on the market."
"DDoS protection is this product’s most valuable feature."
"Compute@Edge features are valuable to me."
"Fastly provides CDN, WAF, image optimization, and IP restriction."
"The product's initial setup phase 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."
"Fastly has positively impacted my organization by helping to obtain better solutions in less time and in a much more traceable way."
"Rate limiting is a good feature that protects from volumetric attacks."
"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."
"Its initial setup process is straightforward."
"We use the product for faster content delivery with low latency."
"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."
"The fact that it just delivers what it is supposed to do is its most valuable feature...The initial setup is very straightforward."
"The most valuable feature of the solution stems from the fact that one can access Windows Azure CDN from anywhere."
"I like that CDN offers a routing feature."
"The geolocation feature is very important because many colleagues travel worldwide and need to access information from anywhere. The product has improved security."
"It is a stable solution."
 

Cons

"There could be more courses with engineers. I like e-learning, however, having a specialist in a classroom is more comfortable for me."
"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."
"I think they have failed with their technical support."
"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."
"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."
"The pricing could be improved."
"Several features that I think is essential is not available in the free and business package."
"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."
"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."
"Fastly's customer service area needs improvement."
"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."
"Fastly can be improved in certain areas such as VCL, which is powerful but has a steep learning curve for normal users."
"We are not getting quick responses from Fastly technical support engineers. Sometimes they depend on their D3 developers."
"What I don't like about Fastly is that they charge a heavy price."
"Another downside of Fastly is that when we wanted to migrate our API domains, it's lacking the WebSocket protocol."
"They should include configuration for cache rules."
"The high price of Windows Azure CDN is an area of concern where improvements can be made."
"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."
"Azure is continuously improving its CDN but the documentation should be up-to-date."
"Exploring shared access solutions with cloud accounts would be a beneficial choice."
"We have experienced issues with switch connectivity."
"The solution’s pricing could be improved."
"I aim to enhance the reporting."
