Related domain detection lets you monitor your zone for lookalike domains that pose a risk to your organization. Related domains can be used for phishing. They can also be used to create a fake website, impersonate a brand, and more.

If you enable related domain detection for a zone, the Security Analytics page gives you a high-level view of risky domains in a zone. To view more data, view the related domains report. In the related domains report, you can manage these domains, view the domains that are a critical or high risk to your organization, and take down fraudulent domains. For more information, see Monitor and protect zones and Take down fraudulent domains.
