Dark Web Scan in WatchGuard Cloud identifies data breaches that include your user accounts. You can scan for an email address or domain name. When you scan data breaches for a domain, the results list all data breaches for the domain.
You cannot scan 3000+ public domains such as gmail.com, yahoo.com, Microsoft.com, outlook.com, etc.
To view a list of excluded domains, see https://github.com/WatchGuard-Threat-Lab/Dark-Web-Scanner-Info/blob/master/Public-Domains.txt.
You can view data breaches for an email address that includes a public domain, such as firstname.lastname@example.org.
