Information
This setting lets you decide whether employees can browse using InPrivate website browsing.
The recommended state for this setting is: Disabled.
Rationale:
Even though web filter logs can monitor traffic to and from websites, it is always a good practice to try and keep multiple source of logs. It can also be helpful to keep user from privately browsing in order to troubleshoot malicious site visits if a machine has become compromised.
Solution
To establish the recommended configuration via GP, set the following UI path to Disabled:
Computer Configuration\Policies\Administrative Templates\Windows Components\Microsoft Edge\Allow InPrivate Browsing
Note: This Group Policy path may not exist by default. It is provided by the Group Policy template MicrosoftEdge.admx/adml that is included with the Microsoft Windows 10 Release 1511 Administrative Templates (or newer).
Note #2: In the Microsoft Windows 10 Release 1511 Administrative Templates, this setting was named Turn off InPrivate browsing, but it was renamed starting with the Windows 10 Release 1607 & Server 2016 Administrative Templates.
Impact:
Employees will not be able to use InPrivate website browsing.
Default Value:
Enabled. (Employees are able to use InPrivate browsing.)
