DNS over HTTPS (DoH) for web browsers provides online security by encrypting DNS queries, traditionally transmitted in plaintext. This encryption shields queries from interception and manipulation, mitigating risks associated with unauthorized surveillance or malicious activities. With DoH, each query is encapsulated within a secure tunnel, ensuring confidentiality and integrity as users navigate the internet. This technical advancement enhances the security posture of web browsers, safeguarding sensitive online interactions from potential threats.
When traffic is sent over DoH, the source in the reports would show "Unknown."

NOTE: To obtain your FQDN go to the General page of the Create New Security Policy wizard in the Cloud Services Portal(Cloud Services Portal > Policies > Security Policies > Create New Security Policy > General). Copy the auto-generated FQDN, or click regenerate to generate a new FQDN. Note that DoH per Policy must be enabled in order to obtain the FQDN..
