Identity integrations provide information about all the users, and the applications they are accessing that the Identity provider is aware of. A good example of an Identity integration is Okta. Okta is often used to configure Single Sign On to multiple other applications. By connecting to Okta, Trelica will add all these applications to Trelica's inventory, as well as information about which users are using these applications.
Usage integrations provide information about specific applications, typically in more detail than can be provided by an Identity provider.
Finance integrations import transaction data from an accountancy tool. This can uncover spend with vendors which can be used to add to (or map to existing) applications in the inventory, as well as importing the associated spend data.
