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.""It is a stable solution. I rate the stability a ten out of ten...I rate the scalability a ten out of ten.""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.""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.""Its most significant benefit to date is the speed with which it refreshes DNS records on the internet once you change it. If you are changing a website or registering a new record, it is very quick.""The attacker won't have details since my public IP is anonymous. It offers us good privacy.""The most valuable feature of Cloudflare DNS is security.""Its ease of integration with Office 365 and the fact that it's a good product compared to what I had before"

"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."

More Quad9 Pros →

"I believe they currently have this feature, but there will most likely be integration with APIs so we can control some features through API.""There might be helpful if there was some web application firewall feature.""The documentation could improve 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 analytics, basically the dashboard, doesn't have much to it.""The tool needs to improve caching of servers. The product needs to include PFX certificate as well.""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.""We have noticed multiple instances where Cloudflare falsely indicates that our servers are down, even when there is no actual load on them. This makes it challenging for us to identify the exact issue."

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.
