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."
"The most valuable feature of the solution is external DNS. It is also very secure. They have their own main server and once you configure it, the product takes care of everything. There are no issues in resolving IPs and low latency is also present."
"There is no service as mature as Cloudflare that is also as easy to use, reliable, and hosted from excellent infrastructure."
"From a technical point of view, Cloudflare is the best CDN."
"There are key things that are used for our enterprise customers, such as Lambda and DNS."
"The most valuable feature is its usability."
"The solution is very good at mitigating threats."
"Easier http to https redirect using page rules"
"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."
"Its initial setup process is straightforward."
"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."
"The product's initial setup phase is straightforward."
"Compute@Edge features are valuable to me."
"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."
"In summary, this solution is easy to manage, quick to deploy, and all of my customers are happy."
"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."
"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."
"The most valuable feature of the solution stems from the fact that one can access Windows Azure CDN from anywhere."
"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 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."
"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."
 

Cons

"The integration of LLMs on the dashboard is something that is needed in the tool."
"We experienced some downtime in the fall of 2013, causing us to switch to Incapsula."
"Areas like how assessment, discovery, and payload are dealt with and how it all comes into your organization can be considered when trying to make suggestions to Cloudflare for improvements."
"Technical support is not well developed. While there are good engineers, Cloudflare does not offer hands-on technical support to fix customer problems but rather a self-service model."
"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."
"Technical support is lacking."
"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."
"Integration involving API with other products could be more user-friendly."
"Another downside of Fastly is that when we wanted to migrate our API domains, it's lacking the WebSocket protocol."
"The product should provide improved bot detection and management."
"Support is not that great."
"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."
"Fastly can be improved in certain areas such as VCL, which is powerful but has a steep learning curve for normal users."
"What I don't like about Fastly is that they charge a heavy price."
"It's not easy to start with Fastly if you don't have VCL knowledge, so it appears very complex at the beginning."
"Azure is continuously improving its CDN but the documentation should be up-to-date."
"Windows Azure CDN should lower its prices."
"Exploring shared access solutions with cloud accounts would be a beneficial choice."
"They should include configuration for cache rules."
"The solution’s pricing could be improved."
"There were a few bugs that were very disappointing. So, that is a part of the reason why we started using Fastly."
"The high price of Windows Azure CDN is an area of concern where improvements can be made."
"We have experienced issues with switch connectivity."
 

Pricing and Cost Advice

"We don't have any issues with the price."
"The cost primarily depends on the size of the organization."
"I give the price a five out of ten."
"When you compare Cloudflare DNS to other solutions, such as Akamai, the price is reasonable."
"The solution is expensive when compared to other products but offers unlimited bandwidth."
"That is one of the great features. I was able to access the majority of the features and services for free."
"We are using the free version."
"I believe their performance has improved, but I'd like to refrain from discussing the pricing aspect related to the cloud. The pricing, in my opinion, could be simplified, and I think they should consider reevaluating the pricing for support, as it can be quite high. At times, this cost can make it challenging to choose CARFAGuard or opt for the support."
"The pricing has been very competitive."
"It is an expensive solution."
"The solution is cheaper than other products in the market."
"In my opinion, Fastly is priced competitively."
"You need to pay a premium price for the tool."
"I've generally found Fastly to be very competitive in pricing, especially around Compute@Edge."
"Fastly is less expensive than one of its competitors."
"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 tool's pricing is cheap."
"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."
"It comes at a relatively affordable cost."
"The solution's price is above the medium range."
"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 pricing is extremely high, almost 9 out of 10."
"The tool's pricing is cheap."
