We compared Cloudflare DNS and Quad9 in several parameters based on reviews we have collected from users and you can find our conclusion below:

  • Ease of Deployment: Cloudflare DNS offers a user-friendly initial setup that can be completed in a few hours. It provides helpful documentation covering their functionality and API for advanced users. Quad9's setup process is uncomplicated and can be finished in less than an hour. Louis Geoffroy, the President at IDEBUG, told us that it was "straightforward if you know what you're doing, and it's easy to use overall."

  • Features: Cloudflare DNS excels in quick DNS record refreshing, easy domain registration, IP address protection, Office 365 integration, caching capabilities, DNS proxy, and DDoS protection. Cloudflare users also shared with us that they are seeing low latency performance and that they found Cloudflare API to be useful. For Quad9, we did not receive enough information about valuable features.Benoit Tellier, an IT Telehealth Specialist mentioned that "The most valuable feature of Quad9 is that it is a free solution".

  • What needs improvement: Cloudflare DNS could improve its API, SSO, and active directory integrations. Users also mention limitations in the free plan and issues with server downtime indications. Quad9 could enhance its offerings by adding personalized DNS filtering and improving responsiveness.

  • Pricing and ROI: The cost of setting up Cloudflare DNS varies based on usage. On the other hand, Quad9 is completely free to use. Both solutions provide security advantages that make it difficult to assess the financial return on investment. Since Quad9 is the free option, it yields positive results.

  • Service and Support: Cloudflare DNS receives praise for its dependable and satisfactory customer service. Users appreciate the highly regarded documentation that contributes to positive experiences. Quad9's website is considered practical and effective in providing the necessary information.

Based on user feedback, Cloudflare DNS is a highly recommended solution. Users appreciate its easy setup, quick DNS record updates, strong security features, worldwide coverage, scalability, reasonable pricing, compatibility with Office 365, caching ability, and minimal latency. They also value the Cloudflare API for creating distinct environments and updating zone codes. On the other hand, Quad9 is regarded as simple to configure and cost-effective, but it lacks personalized DNS filtering and raises concerns about performance and responsiveness.

Quotes From Members
We asked business professionals to review the solutions they use.
Here are some excerpts of what they said:
"The solution automatically detects and responds to certain types of traffic based on geolocation.""I get a lot of value from Cloudflare's API because it enables you to build a separate environment inside the solution. You can create a domain for performing test requests before you move to the production environment and connect various domains.""The attacker won't have details since my public IP is anonymous. It offers us good privacy.""It is a stable solution. I rate the stability a ten out of ten...I rate the scalability a ten out of ten.""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.""The solution is stable, and the DNS servers are simple to use.""The most valuable feature of the solution is external DNS. It is also very secure. They have their own main server and once you configure it, the product takes care of everything. There are no issues in resolving IPs and low latency is also present.""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 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."

More Quad9 Pros →

"Cloudflare doesn't have a reverse lookup. We can only do a DNS lookup to get the IP address from the hostname. It doesn't work if you want to look up the hostname from an IPA address.""The tool needs to improve caching of servers. The product needs to include PFX certificate as well.""Cloudflare should add more documentation and pricing to the cloud version.""The analytics, basically the dashboard, doesn't have much to it.""An integrated SSO feature would be useful for Cloudflare DNS.""Cloudflare's free plan is limited to 5,000 records for their free plan. They should increase that. For example, if I create a domain called and a subdomain called, my record count will be two. I can make a maximum of 5,000 subdomains. However, if we use our own DNS hosted on another provider, there is no limit. Their free plan also lacks name server customization.""The documentation could improve for Cloudflare DNS.""There might be helpful if there was some web application firewall feature."

More Cloudflare DNS Cons →

"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."

    Powering over 38% of managed DNS domains, Cloudflare runs one of the largest authoritative DNS networks in the world. With an average of a few milliseconds query speed, we have the fastest performance of any managed DNS provider. DNS updates happen within seconds, making DNS propagation delays a thing of the past.

    Quad9 is a free, recursive DNS service that replaces your ISP's or company's default domain name server (DNS) settings. Quad9 blocks lookups of malicious host names from an up-to-date list of threats when your computer makes any internet transaction that uses the DNS.

    This blocking action protects your computer, mobile device, or IoT systems against a variety of risks, including malware, phishing, spyware, C2 command-and-control domains, exploit kit-compromised sites, and botnets. It can also boost performance while ensuring privacy.

    Quad9’s service uses threat intelligence from a variety of sources, including:

    • Cisco
    • F-Secure
    • Netlab
    • IBM X-Force
    • Anti-Phishing Working Group (APWG)

    Quad9 employs DNSSEC, which assures that the results supplied are accurate. It also filters out websites that have been categorized as hazardous using blacklists provided by various security suppliers.

    Quad9 supports DNS over TLS (DoT) and DNS over HTTPS (DoH). It’s been increasingly obvious in recent years that standard DNS has significant security flaws due to a lack of encryption. As a result, it is more susceptible to DNS hijacking. Quad9 users are effectively protected from cyber criminals as well as government censorship.

    The Quad9 service is run by the Quad9 Foundation, a non-profit organization based in Switzerland whose purpose is to make the internet a safer and more reliable place for everyone.

    Quad9 Features

    Quad9 has many valuable key features. Some of the most useful ones include:

    • Privacy: Quad9 is the custodian of a worldwide DNS infrastructure that allows people to communicate and participate in governance and civil society more easily. Quad9 protects their users' privacy by not collecting personal data; Quad9 protects their consumers' privacy by preventing connections between their devices and harmful Internet sites. Quad9 provides users with performance by placing servers in hundreds of communities all over the world to deliver service on a local level. Because of their non-commercial position, they are able to give equal emphasis to regions that are otherwise underserved.
    • Addresses: Quad9 offers a number of distinct recursive DNS service options. Each has its own IP address (or, in certain situations, hostname), which you may use to configure your devices.
    • Threat blocking: Both commercial and publically available threat intelligence feeds have been merged by Quad9. Each was picked based on its shown ability to identify threats and provide a comprehensive set of capabilities for detecting exploits, malware, ransomware, spyware, and other potentially hazardous websites. Quad9’s threat intelligence (TI) partners provide us with data on feeds that are rapidly updated and dispersed as new domain-based risks emerge, and these domains or hosts are updated in their lists.
    • Locations: Quad9 systems are available in more than 150 places in 90 countries, with significant expansion planned. Quad9's servers are primarily positioned at internet exchange points, which are the locations with the highest concentration of interconnections within a typical network region.
