Hello @Parmeshwar Jadhao · Thank you for reaching out.

Yes, we can restrict access to Azure Portal by using Condition Access Policy, which is a feature included with Azure AD Premium P1 License.

Steps:

• Navigate to Azure Portal > Azure Active Directory > Security > Conditional Access > Named locations > +New Location > Type a name and add IP address that you want to allow Azure Portal access from. To add a specific IP use /32 CIDR value as shown below:
  
• Navigate to Azure Portal > Azure Active Directory > Security > Conditional Access > Policies > +New Policy > Configure below settings:
• Users and Groups : Select required users.
• Cloud apps or actions : Select apps > Microsoft Azure Management.
• Conditions : Locations > Include > Any location. Exclude > select the location created in first step,.
• Grant : Block access
• Enable policy > On > Click on Create button.

This will block access to Azure Portal from Any location, except your custom location.

By definition, being a public cloud offering, Azure is available from anywhere, any time. If you want to restrict access, you need to enforce this as part of the login process, by leveraging something like Conditional Access, or redirecting the auth process (federation) and imposing restrictions there.

Can provide some link or guide on the "redirecting the auth process (federation) and imposing restrictions there" part?

Assuming that I use this feature to block portal access to a group called "Developers", will this feature also block the CLI access? (is it possible to allow CLI access but block the access to portal.azure.com?)
