Temporary Workers with BYO Laptops
Provisioning and shipping temporary machines for contractors, consultants, travelers, and interns is not practical, but you may want these people to work inside your Microsoft tenant.
AVD (Azure Virtual Desktop) is a great solution, but unless you have engineers with Azure skills, AVD can be overly complex.
In the absence of a solution, contractors could be accessing your tenant from unsecured personal laptops. Or perhaps they use Dropbox and Gmail to collaborate with your company.
