Understanding internal and external applications

When securing an application, the first thing to consider is whether the application is an internal application or an external application.

Internal applications, sometimes referred to as first-party applications, are applications owned by the enterprise. It does not matter who developed the application, nor does it matter how it is hosted. The application could be an off-the-shelf application, and it can also be a Software as a Service (SaaS)-hosted application, while still being considered an internal application.

For an internal application, there is no need to ask the user to grant access to the application when authenticating to the user, as this application is trusted and the administrator that registered the application with Keycloak can pre-approve the access on behalf of the user. In Keycloak, this is done by turning off the Consent Required option for the client, as shown in the following screenshot:
