Featured Reviews

Anand Yadav - PeerSpot reviewer
Manager Technical Support Engineer at Softcell Technologies Limited
Centralized DNS governance has reduced incidents and supports secure hybrid deployments
Azure DNS could be improved with more advanced DNS analytics, richer auditing reporting, and better visibility into DNS query patterns and troubleshooting data. There is also a desire for deeper security-focused features such as enhanced DNS anomaly detection, more detailed change tracking, and stronger integration with broader security monitoring platforms for threat investigations and compliance reporting. One additional improvement desired in Azure DNS is more advanced DNS security intelligence and automated policy recommendations. For large enterprise environments, features such as DNS anomaly detection, easier cross-zone dependency visibility, and enhanced reporting for compliance and security investigation would provide greater operational and cybersecurity value.

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 the solution is that it is a stable product."
"The most valuable feature of the solution is the simplicity of putting DBs."
"The speed of the queries is valuable."
"One of the key benefits of Azure DNS is its integration with other Azure services. As it is a solution developed by Microsoft, it is easy to integrate with other Azure offerings. Azure DNS also includes Defender for DNS, a feature that protects against anomalies and threats on the DNS. This added security is provided directly by Microsoft. The integration and security features of Azure DNS make it a valuable option for users of the Azure cloud platform."
"The DNS resolution is the most valuable feature."
"I would say make use of Azure DNS; it is a very good solution."
"Azure DNS provides value beyond its user-friendly interface and easy learning curve."
"Regarding return on investment for Azure DNS, because of the automatization, there is a big return on investment as it's easy to implement it, and you don't necessarily need the expertise to do that."
"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

"There are issues with the cloud systems."
"The security features and stability needs to be bettered."
"Azure DNS could be improved with more advanced DNS analytics, richer auditing reporting, and better visibility into DNS query patterns and troubleshooting data."
"The initial setup of this solution could be less complex and require less manual configurations."
"The solution lacks scalability."
"The DNSSEC feature is not yet available on the DNS server so it needs to be added."
"Domain registration is one of the problems. We need to go to application services or web apps to purchase the domain instead. If that were to be equivalent to AWS's Route 53 that would be good. But, it is not as flexible as that."
"The process of creating a virtual mission 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

"We have an enterprise license agreement with Microsoft. Their pricing is competitive. I would rate it a three and a half out of five."
"The solution payment model is based on how many users use it. This is not an expensive solution, but it can depend on how long we use it. However, if the price was decreased it would be helpful."
"The solution itself is free but you need to pay for the Microsoft Azure infrastructure and host your domains in Azure to use it."
"To use Azure DNS, I need to buy the license meant for Windows Server."
"We use the tool's free version."
"The solution's price is reasonable."
"Azure DNS is a cheap solution, and I rate it a two out of ten for pricing."
"The price is low and it's a reasonable price for that product."
"The price of Quad9 is free."
