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.

Security architecture shields infrastructure but dashboard needs enhancement
The Azure DDoS Protection plan is essential for environments like ours that are highly exposed to potential attacks, especially since DDoS attacks have become common. The security architecture with Azure DDoS Protection is critical for safeguarding our financial organization's infrastructure. Although implementing it is pricier, it is worth using since our applications are entirely in Azure.

Optimized ecommerce performance and improved access control through image handling and IP filtering
I believe that Fastly should provide guidelines for their WAF blocking rules. It should be public what the rules are that are blocking their contents. I believe Fastly should provide regional IP addresses instead of POP IPs. Fastly should provide features similar to Cloudflare regarding a block list. Additionally, a POP address should be there with a wide range of IP addresses provided, public static IP addresses, so customers can integrate egress IPs. Fastly should provide WebP image processing on the backend instead of on the fly. It would be a very useful feature to avoid unnecessary time for browser to browser and local cookies. I believe that Fastly service has a few gaps. We are not getting quick responses from Fastly technical support engineers. Sometimes they depend on their D3 developers. There should be transparency.

Quotes from Members

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

Pros

"The overall performance of this solution is what makes it one of the best solutions on the market."

"The API gives us the ability to remote control our DNS settings."
"So far I use free tier and happy with it."
"The solution is a great fit for customers who want unlimited bandwidth."
"Cloudflare DNS is widely used, and it's good for websites. If we use Cloudflare DNS and update one record, it updates in their office instantly."
"Cloudflare offers CDN and DDoS protection. We have the front end, API, and database in how you structure applications."
"Easier http to https redirect using page rules"
"The integration of various tools with Azure Firewall, like DDoS Protection, Web Application Firewall, and Azure Front Door, is quite effective."
"This solution is the best option for us because we use a lot of Microsoft products. So, it is easy for us to deploy or integrate any features or products."
"Azure is easy to set up and widely used by our clients."
"Azure is easy to set up and widely used by our clients."
"The most valuable feature of Azure DDoS Protection is that it performs well."
"Azure DDoS Protection offers superior protection against denial-of-service attacks."
"The most valuable feature of Azure DDoS Protection is that it performs well."
"AI capabilities are very good. I would rate them an eight out of ten."
"Compute@Edge features are valuable to me."
"In summary, this solution is easy to manage, quick to deploy, and all of my customers are happy."
"The product helps our organization to access sites located in different regions quickly."
"Rate limiting is a good feature that protects from volumetric attacks."
"Fastly uses configuration versioning, where you can deploy a new version in less than one minute."
"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."
"Its initial setup process is straightforward."
"Fastly provides CDN, WAF, image optimization, and IP restriction."
 

Cons

"There are some issues with the CDN services."
"The product support needs to be accessible from more places, a wider area of coverage."
"Cloudflare should add more documentation and pricing to the cloud version."
"There are some issues with the CDN services."
"I think the APIs are a little bit hard for us to work with. The APIs could be more open so that we could integrate better with our SolarWinds or our monitoring solution."
"Technical support is lacking."
"At the end, it is worth than giving your house keys to the NSA."
"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."
"Azure DDoS Protection could improve on the reporting."
"I suggest adding more services and additional services, which would be beneficial."
"The dashboard lacks insights and user-friendliness, as most data is logged into metrics like Log Analytics workspaces."
"Sometimes, it is hard for our staff to keep track of changes (in the GUI) between different projects, because there are constant changes."
"I have noticed some false positives with the Web Application Firewall yet not with DDoS Protection."
"The implementation of Azure DDoS Protection results in a decrease in our bandwidth capacity and should be optimized to reduce resource consumption."
"Azure DDoS Protection could improve on the reporting."
"Sometimes, it is hard for our staff to keep track of changes (in the GUI) between different projects, because there are constant changes. As a result, it is hard to manage, recall, and see all the features because they have been moved from one place to another."
"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."
"The solution's pricing could be better."
"Support is not that great."
"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."
"It's not easy to start with Fastly if you don't have VCL knowledge, so it appears very complex at the beginning."
 

Pricing and Cost Advice

"The price of the solution is expensive."
"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."
"When you compare Cloudflare DNS to other solutions, such as Akamai, the price is reasonable."
"We are using the free version."
"We are using the free tier of the solution."
"There are no additional costs beyond the standard licensing fees."
"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."
"It is an expensive solution."
"You can test it for a certain period of time free of charge. You can have a free account. You can test it to compare its pros and cons with other products that you are testing."
"In my opinion, Fastly is priced competitively."
"The solution is cheaper than other products in the market."
"Fastly is less expensive than one of its competitors."
"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."
"The pricing has been very competitive."
"It is an expensive solution."
