Azure B2b Authentication Question

Still learning Azure B2b and I have a question I could not find an answer for. Users are invited from my corporate tenant to another one to access an application. Everything works fine.

My users are able to go to their home PC's hit the link to the app in the other tenant and access the application after providing their credentials and MFA. How do I stop this and force my users to only connect to the 3rd party app after they have logged into my network from the office or from their work laptop once they connect via VPN? Thanks!

    Hi @Gerrit

    You can use Conditional Access Policies to define locations (specific Public IPv4 addresses such as your offices/vpn):

    Define locations

    Block access by location with Azure AD Conditional Access
