I am creating a SaaS, multi-tenant application, where each tenant will have a custom domain like tenant1.myWebApp.com, tenant2.myWebApp.com ... tenantX.myWebApp.com.

  • On Azure, I can add those custom domains. I noticed that there is a max of 500 custom domains you can add to your App Services, and I expect more tenants than that.
  • To solve this I can add a wildcard domain like *.myWebApp.com. However, this will allow anyDomainX.myWebApp.com to access my App. How can I prevent this? Is there a way to block unauthorized domains from accessing your App in Azure?

How to, while using wildcard domain on Azure, prevent some custom domains from accessing your WebApp?

  • We can restrict the users to block users from specific domain, we can add a deny list

Log into the Azure Portal => Azure Active Directory => Users => Users Settings => External users => Manage external collaboration settings.

enter image description here

Under Collaboration Restrictions , select Deny invitations to the specified domains

  • Under target domain, enter the names of the domains which you want to block
