Featured Reviews

Anand Yadav - PeerSpot reviewer
Manager Technical support 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 best feature is the domain register. The other great feature is that whenever you create any resources, Azure DNS will automatically create a record for you."
"It is a very stable solution."
"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."
"Azure DNS is a user-friendly and very easy-to-manage solution."
"Azure DNS provides value beyond its user-friendly interface and easy learning curve."
"The most valuable feature of the solution is that it is a stable product."
"The solution allows you to host DNS service without using Azure's servers."
"The most valuable feature is the ease of installation."
"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

"I did not see any improvements required."
"Azure DNS could improve by having more updates."
"There are issues with the cloud systems."
"The web interface to manage the solution must be made easier."
"While it's stable, there's always room for improvement to ensure it remains reliable."
"What needs improvement in Azure DNS is visibility in terms of troubleshooting. It's similar to the area for improvement in Azure Network Watcher, where I can see how the source is going out if I'm troubleshooting a source destination. I can also see the destination. As for seeing how the packet travels, that's what should be improved. It's still lacking in visibility. Suppose I'm looking into backend machines, and if I'm hitting another NPM machine or any machine on the other side, there should be visibility. The tool should tell you that a specific machine is passing through a VPN gateway or route table, routing to a third-party firewall, and then dropping. Azure DNS should show an accurate answer to help the customers, which is its area for improvement."
"The process of creating a virtual mission could be improved."
"Azure DNS could be improved with more advanced DNS analytics, richer auditing reporting, and better visibility into DNS query patterns and troubleshooting data."
"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 is moderately priced."
"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."
"Azure DNS is a cheap solution, and I rate it a two out of ten for pricing."
"I would describe Azure DNS as a cheaply priced product."
"We use the tool's free version."
"To use Azure DNS, I need to buy the license meant for Windows Server."
"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 pricing is expensive."
"The price of Quad9 is free."
