Disable Certificate Transparency enforcement for specific URLs
Verified with Microsoft Edge 152.0.4191.53 — updated on July 10, 2026
Supported on: Microsoft Edge version 77, Windows 7 or later
Path in the GPO console
Computer Configuration\Administrative Templates\Microsoft Edge User Configuration\Administrative Templates\Microsoft Edge Description
Disables enforcing Certificate Transparency requirements for the listed URLs. This policy lets you not disclose certificates for the hostnames in the specified URLs via Certificate Transparency. This lets you use certificates that would otherwise be untrusted, because they weren't properly publicly disclosed, but it makes it harder to detect mis-issued certificates for those hosts. Form your URL pattern according to https://go.microsoft.com/fwlink/?linkid=2095322. Because certificates are valid for a given hostname, independent of the scheme, port, or path, only the hostname part of the URL is considered. Wildcard hosts aren't supported. If you don't configure this policy, any certificate that should be disclosed via Certificate Transparency is treated as untrusted if it's not disclosed. This policy doesn't work as expected with file://* wildcards. Example value: contoso.com .contoso.com

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.
