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 fast and secure DNS."
"This solution has improved the security of our organization."
"When using services like Heroku, Cloudflare is very useful for CNAME flattening. I also use it for their end-to-end SSL with TLS authentication on nginx for securing servers."
"Cloudflare is very straightforward."
"It is very clear and the information is very useful."
"Cloudflare offers CDN and DDoS protection. We have the front end, API, and database in how you structure applications."
"It is a stable solution. I rate the stability a ten out of ten...I rate the scalability a ten out of ten."
"The solution automatically detects and responds to certain types of traffic based on geolocation."
"Compute@Edge features are valuable to me."
"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 uses configuration versioning, where you can deploy a new version in less than one minute."
"In summary, this solution is easy to manage, quick to deploy, and all of my customers are happy."
"Fastly has positively impacted my organization by helping to obtain better solutions in less time and in a much more traceable way."
"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 provides CDN, WAF, image optimization, and IP restriction."
"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."
"The UI is very intuitive."
"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."
"We use the product for faster content delivery with low latency."
"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."
"It is a stable solution."
"I like that CDN offers a routing feature."
 

Cons

"Several features that I think is essential is not available in the free and business package."
"Technical support is lacking."
"DNS Management."
"Sometimes their more advanced caching tools can cause higher first-byte times and problems with JavaScript."
"There should at least be a read-only view of the data so that resellers can properly support the clients."
"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."
"The solution could use more analytics on the backend to give us more insights into everything. More reports would be helpful."
"There should be a specific price list for enterprise-level customers."
"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."
"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 can be improved in certain areas such as VCL, which is powerful but has a steep learning curve for normal users."
"Support is not that great."
"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."
"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."
"It's not easy to start with Fastly if you don't have VCL knowledge, so it appears very complex at the beginning."
"The response time of the support team must be improved."
"The solution’s pricing could be improved."
"The high price of Windows Azure CDN is an area of concern where improvements can be made."
"Windows Azure CDN should lower its prices."
"I aim to enhance the reporting."
"They should include configuration for cache rules."
"Azure is continuously improving its CDN but the documentation should be up-to-date."
"There were a few bugs that were very disappointing. So, that is a part of the reason why we started using Fastly."
 

Pricing and Cost Advice

"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."
"We are using the free tier of the solution."
"The price of the solution is expensive."
"That is one of the great features. I was able to access the majority of the features and services for free."
"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."
"A free version of the solution is available."
"The price is reasonable."
"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 solution is cheaper than other products in the market."
"The pricing has been very competitive."

"It is an expensive solution."
"In my opinion, Fastly is priced competitively."
"I've generally found Fastly to be very competitive in pricing, especially around Compute@Edge."
"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."
"The pricing is extremely high, almost 9 out of 10."
"It comes at a relatively affordable cost."
"The pricing of the solution depends on usage and varies based on the company's needs. If you want additional features like advanced logging, it will be pricier. However, it could be cheaper if you don't need those features. It all depends on the resources and requirements."
"The solution's price is above the medium range."
"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."
