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

"The attacker won't have details since my public IP is anonymous. It offers us good privacy."
"Even when there is a high load on our servers, Cloudflare is able to cache the data and serve it to users, ensuring they can still access the website."
"The initial setup is extremely easy but will require access to your Domain Name Servers."
"The API gives us the ability to remote control our DNS settings."
"There are key things that are used for our enterprise customers, such as Lambda and DNS."
"If you don't want to spend too much time hosting your own DNS server or managing the domain, Cloudflare is a great way to rapidly get websites and services online."
"Because our website is blazing fast it improves our conversion rates."
"I like Cloudflare's application gateway and DDoS protection."
"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

"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."
"At the end, it is worth than giving your house keys to the NSA."
"Flexible SSL is nothing more than an illusion of security that you're presenting to your visitors."
"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 product needs to improve its automation."
"Yes, there were a few times when some of their CDN nodes would fail, creating serious speed issues with the site without any warning or notification from their side."
"More insight into analytics and threats would be a good place to start improving 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."
"Quad9 could improve by having more free features, such as custom DNS filtering."
"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."
 

Pricing and Cost Advice

"A free version of the solution is available."
"I give the price a five out of ten."
"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."
"There are no additional costs beyond the standard licensing fees."
"The solution is expensive when compared to other products but offers unlimited bandwidth."
"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."
"We are using the free version."
"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 price of Quad9 is free."
