Azure Enterprise App Authentication Report

Purpose

Surface how enterprise applications in an Azure tenant are actually being used — sign-in patterns, last sign-ins, and audit trails — so unused apps and authentication anomalies can be identified and addressed.

Description

A Python-based reporting job runs on Azure Functions, querying the Microsoft Graph API for enterprise application sign-in activity, last sign-in dates, and audit log events. The collected data is rendered into a formatted HTML report that highlights usage patterns and potential security issues, giving administrators a recurring, at-a-glance view of application access across the tenant.
