What is the difference between Entreprise App and App registration? What is the security risk of Entreprise App and App registration

Hi @TEST DIALLO

If you have an azure resource like an azure function or web app and you secure that with an app registration, that will create a Service Principal (a way to add your app to azure AD and secure that with AD authentication (very raw explanation))

The service principal for your apps will display under the "Enterprise App" but only under your tenant unless you publish it like this:
https://learn.microsoft.com/en-us/azure/active-directory/manage-apps/v2-howto-app-gallery-listing

if you follow that publish procedure you make it available to other tenants

regarding "My second question, what is the security risk for your company to do not manage these applications "
are you planning to develop an app for other companies to use/integrate with or just for your own company?

App registrations are very safe. Of course there are best practices to secure the Service principal secret or any other authentication means provided: https://learn.microsoft.com/en-us/azure/active-directory/develop/security-best-practices-for-app-registration

Hi,

You can find more details about the difference in bellow answer:

Regarding security risks, you should review the permisions that enterprise app have in your tenant and expecially the application permisions.

Regarding app registration you can review the certicates and secrets and maybe you can rotate them.

Hope this helps!
