Tushar-Patil - PeerSpot reviewer
Offers good performance and helps its users with disaster recovery
Azure DNS has improved our company's domain management and resolution reliability since it provides most of the solutions, especially whatever is required in our organization. My experience of integrating Azure DNS into our company's existing cloud services was easy. For the security and privacy aspect, my company mostly relies on Microsoft. I don't have the expertise to comment on whether Azure DNS has influenced our company's operations from a security and privacy perspective. Azure DNS is a really good product when it comes to scalability and performance for our company's workload. Azure DNS has helped my company with the disaster recovery phase. The product uses cloud features, and since my company has separate regions, we have a backup tool or a backup deduplication technology. The implementation of Azure DNS in our environment benefits the entire organization, but four to five people have access to the solution. I rate the overall product a nine to ten out of ten.

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

"Azure DNS provides value beyond its user-friendly interface and easy learning curve."
"Can be configured to achieve a hundred percent reliability"
"It is a very stable solution."
"The tool is easy to manage and use."
"The most valuable features of Azure DNS are the DNS forwarder and the DNS additional record editions."
"Data protection is paramount across cloud platforms"
"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."
"Azure DNS provides end-to-end P2P connectivity and enhances security, making it more secure and reliable."
"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

"The security features and stability needs to be bettered."
"The web interface to manage the solution must be made easier."
"Azure DNS' documentation needs to improve."
"The DNSSEC feature is not yet available on the DNS server so it needs to be added."
"They should include more integration with other platforms."
"Azure needs to add domain registration to the DNS service."
"The scalability could improve."
"Azure DNS does provide enhanced support for applications and includes several security features to protect against threats. One of the security features it offers is the ability to detect and prevent dangling DNS records, which can be used in cyber attacks. Dangling DNS records occur when a website owner creates a domain name but forgets to remove the CNAME record, leaving the domain vulnerable to takeover by malicious actors. Azure DNS includes security measures to identify and prevent such threats, helping to keep your DNS infrastructure secure. However, if Microsoft could add more security capabilities to the DNS, that would be great to detect and identify anomalies that are happening to prevent cyber threats."
"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."
"Azure DNS is a cheap solution, and I rate it a two out of ten for pricing."
"To use Azure DNS, I need to buy the license meant for Windows Server."
"We use the tool's free version."
"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 pricing is expensive."
"The price is low and it's a reasonable price for that product."
"The solution itself is free but you need to pay for the Microsoft Azure infrastructure and host your domains in Azure to use it."
"The price of Quad9 is free."
