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.

It's easy to use and set up, but I've faced performance problems
I have experience with Quad9 and most other filtering solutions. Quad9 was working well initially, but it started slowing, so I switched to OpenDNS. I recently checked Tom's Hardware, an IT review site, and read a review of seven DNS filters. Open DNS was ranked the fastest, and Quad9 was second. Google was on there too, but they said it didn't filter enough.

Quotes from Members

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

Pros

"Another reason it's awesome is that you don't need your server to handle every request."
"Cloudflare has positively impacted our organization by giving us flexibility to manage the DNS part, being quite fast, and allowing us to manage everything from a single dashboard, which is quite handy."
"The attacker won't have details since my public IP is anonymous. It offers us good privacy."
"I have not had a DDOS attack since, or at least not become unavailable due to DDOS which means my ROI is pretty good."
"Many websites require an SSL certificate because they sell stuff and want SSL. Cloudflare comes with an SSL certificate built in. It's automatic. You sign yourself up for Cloudflare, and an SSL certificate automatically protects your website. You don't necessarily need a certificate if you have a connection between your website and your host, the server, Cloudflare, and the host."
"The solution provides good load balancing and protection against DDoS attacks."
"DDoS protection is this product’s most valuable feature."
"The setup and configuration is also easy to perform and their support is excellent."
"The most valuable feature of Quad9 is that it is a free solution."
"Setting up Quad9 is straightforward if you know what you're doing, and it's easy to use overall."
 

Cons

"More insight into analytics and threats would be a good place to start improving Cloudflare."
"In the last two years, there has been a certain amount of downtime when using the VDM."
"Technical support is lacking."
"One area of improvement is in the Access Rules. Hypothetically, if we wanted to block or challenge traffic outside of the United States, the only way to currently do that (as far as I know) is to enter every single country outside of the United States. That could be a labor intensive job. A solution could be to enable users to create a rule where traffic is only allowed within a certain country."
"The tool needs to improve caching of servers. The product needs to include PFX certificate as well."
"There should at least be a read-only view of the data so that resellers can properly support the clients."
"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."
"Although I think it's quite good, it doesn't provide me with all the features I would expect to have if I were using Imperva."
"It used to work fine for all the devices, but it started to slow and become non-responsive. I would have to reload the page two or three times before all the pages loaded. With OpenDNS, I only need to load the page once."
"Quad9 could improve by having more free features, such as custom DNS filtering."
 

Pricing and Cost Advice

"Cloudflare's pricing is not much higher and is good for middle-level organizations."
"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 don't have any issues with the price."
"When you compare Cloudflare DNS to other solutions, such as Akamai, the price is reasonable."
"I give the price a five out of ten."
"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."
"A free version of the solution is available."
"The price is reasonable."
"The price of Quad9 is free."
