Has helped manage client domains with streamlined access control and threat visibility
I don't know what areas could be improved with Cloudflare WAF; Cloudflare is constantly improving and adding features to their feature set. They're doing a good job, and as far as DNS and support for any domains that I create or my clients create, it's mandatory for me to make sure that they have Cloudflare as their DNS provider. The Cloudflare load balancing capability hasn't really helped in enhancing my website's uptime and resiliency because we don't really get that much traffic; it's mostly remote users, and web hosting is done by a web hosting service. It doesn't pay to try to host your own website.

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 web application firewall brought us good security and a view of the accesses/blocks of the entire domain and subdomain that were accessed both by region (country) and IPs."
"Cloudflare offers CDN and DDoS protection. We have the front end, API, and database in how you structure applications."
"The most valuable feature of Cloudflare DNS is its global reach and it is always evolving."
"Cloudflare consolidates various capabilities into one product, streamlining processes."
"It is easier to configure and develop documentation to see how we have configured firewalls."
"The overall experience with Cloudflare is positive, with a rating of eight out of ten."
"Cloudflare makes it easier for me to handle and set up DNS for multiple users and multiple clients, and basically go in and access their account, make the changes they need, and it's a one-stop shop."
"The most valuable feature is its usability."
"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

"They lack a good way to manage DNS as a company, since everything is relegated to single account logins until you get to the higher levels. They have come out with a paid feature to remedy this, but I have not had a chance to fully review it yet to know if it fixes the access problem."
"The product needs to improve its automation."
"There could be more courses with engineers. I like e-learning, however, having a specialist in a classroom is more comfortable for me."
"Latencies are always a problem."
"The reporting can definitely be improved to offer a lot more explanation on something that may have happened or has actually happened."
"There might be helpful if there was some web application firewall feature."
"It should have easier documentation for the configuration. It's very technical and people who aren't technical should also be able to do the configuration."
"I would like Cloudflare to offer a dedicated account manager for large enterprise clients like us."
"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

"The solution is expensive when compared to other products but offers unlimited bandwidth."
"We are using the free version."
"The product's pricing is minimal compared to other products."
"We are using the free tier of the solution."
"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."
"That is one of the great features. I was able to access the majority of the features and services for free."
"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."
"A free version of the solution is available."
"The price of Quad9 is free."
