Microsoft Defender for DNS provides an additional layer of protection for resources that use Azure DNS's Azure-provided name resolution capability.

From within Azure DNS, Defender for DNS monitors the queries from these resources and detects suspicious activities without the need for any additional agents on your resources.

What are the benefits of Microsoft Defender for DNS?

Microsoft Defender for DNS detects suspicious and anomalous activities such as:

  • Data exfiltration from your Azure resources using DNS tunneling
  • Malware communicating with command and control servers
  • DNS attacks - communication with malicious DNS resolvers
  • Communication with domains used for malicious activities such as phishing and crypto mining
