Carlos Alam Hernandez Baruch - PeerSpot reviewer
Fast and secure deployments simplify operations for government and fintech clients
It is a fast and secure DNS. It is very easy to deploy, and my customers are happy with this tool. Additionally, the CDN performance in Mexico is excellent, providing fast service and tools. It offers reliability during high-traffic periods, ensuring no impact on the environment. It helps my clients avoid using on-premise boxes, simplifying operations as they only use the prices on Cloudflare.
Louis Geoffroy - PeerSpot reviewer
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 most valuable feature of Cloudflare DNS is its global reach and it is always evolving."
"The most valuable feature of Cloudflare is the GUI. You are able to control the solution very well through the interface. There is a lot of functionality that is embedded in the service."
"The most valuable feature is its usability."
"Easier http to https redirect using page rules"
"It is a stable solution. I rate the stability a ten out of ten...I rate the scalability a ten out of ten."
"Cloudflare is a security SaaS provider that provides security and protects us from any application layer attack."
"The tool is user-friendly."
"Cloudflare consolidates various capabilities into one product, streamlining processes."
"Setting up Quad9 is straightforward if you know what you're doing, and it's easy to use overall."
"The most valuable feature of Quad9 is that it is a free solution."
 Cons
"If they improve on the placement of their data centers, it would be better. I'm living in a remote area. I would like to connect to them without any kind of lag."
"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."
"DNS Management."
"There could be more courses with engineers. I like e-learning, however, having a specialist in a classroom is more comfortable for me."
"The solution could be more user-friendly."
"For the free and Pro plans, Cloudflare could use a simple bot to provide information to users. This would improve support, especially for less advanced users who utilize the free components."
"The product support needs to be accessible from more places, a wider area of coverage."
"The pricing could be improved."
"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
"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."
"When you compare Cloudflare DNS to other solutions, such as Akamai, the price is reasonable."
"I think the pricing is competitive. I think as far as licensing is concerned it's pretty straightforward because it's based on domain. It's just that sometimes domains could be tricky with some customers."
"The price is reasonable."
"The product's pricing is minimal compared to other products."
"So far I use free tier and happy with it. You can subscribe to business package if needed."
"The product's pricing is cheap."
"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."
