Computer Configuration\Administrative Templates\Microsoft Edge\Scareware Blocker settings User Configuration\Administrative Templates\Microsoft Edge\Scareware Blocker settings Description
This policy configures the list of trusted domains for Microsoft Edge Scareware blocker. When a website's source URL matches any domain in this list, Microsoft Edge Scareware blocker doesn't analyze that site. This policy takes effect only if the ScarewareBlockerProtectionEnabled policy is enabled. If you enable this policy, Microsoft Edge Scareware blocker trusts the specified domains. If you disable or don't configure this policy, Microsoft Edge Scareware blocker analyzes all sites. Example value: mydomain.com myuniversity.edu

BETAConfigure the state, scope and options, then generate .reg, PowerShell, Intune and SCCM outputs — or add the setting to a multi-setting collection.
These exports write the registry — this is not a managed GPO. ⓘ
Applying both scopes creates an ambiguous configuration (computer takes precedence over user). Only do this intentionally.
