There needs to be a policy to enable Edge Secure Network

[HotCakeX]

As soon a single policy is set for Microsoft Edge, either through group policy or registry, the Edge Secure Network becomes unavailable.

There needs to be a policy to enable it again. Using a registry key or local policy to control Edge doesn't mean it's controlled by an organization or personal Microsoft accounts are not used.

I am having this exact same issue. I do not have a work profile signed into Edge, though I do have a business e-mail in Outlook. But that should not be affecting Edge. Edge is only my personal account. Windows is only my personal account. No other profiles are on my Surface Pro. Yet Edge Secure Network reports, as OP, that it is "managed", even though edge://management/ tells me it is NOT managed.

Someone from the Edge team should take a look at this..

When configuring Microsoft Edge through Group Policy or the registry, certain features, such as Edge Secure Network, may become unavailable if policies conflict with the feature's requirements. Some policies might inherently disable the Edge Secure Network feature due to conflicts in security settings.

You could modify this key in the reg. This key allows the Edge Secure Network feature to remain enabled even when other policies are applied.
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Edge

Create a new DWORD:
Name: SecureNetwork Type: REG_DWORD Value: 1

If you are using Group Policy to manage Microsoft Edge, you can configure the relevant policy to ensure Edge Secure Network remains available.

Computer Configuration > Administrative Templates > Microsoft Edge

Look for a policy setting that explicitly enables the Edge Secure Network feature or ensures that policies do not conflict with its availability.

@question92120 I modified that key in the registry as you suggested, and the Edge Secure Network feature completely disappeared from the settings. I removed the changes to the registry and the feature did not reappear.
