Change the managed browser restriction policy to allow for alternative managed browsers
The Intune Managed Browser is pretty bare bones.
Intune provides iOS and Android SDKs to create managed apps, so the SDKs could be used to implement other managed browsers (i.e. a browser that implements the copy/paste restriction policies, etc.)
But the managed browser restriction policy is just a boolean, you can either require managed browser for links in managed apps or not. So you can't specify an alternative managed browser.
Why not change the managed browser restriction policy so that it allows you to specify a managed browser of your choice? This way others in the ecosystem could use the SDKs to implement alternative managed browsers.
We need a solution, that says these domains, need to use the Intune managed browser for secure access. If the domain is not in the list, automatically use Safari or other browser to access all other sites like Google.com
