Understanding Identity Management: A Comparative Analysis of Active Directory and Leading Platforms

Introduction to Identity Management

In an increasingly digital world, organizations face the challenge of managing user identities and access across a multitude of applications and services. Identity management ensures that the right individuals access the right resources at the right times for the right reasons. Central to this management are identity platforms that provide frameworks for authentication, authorization, and access control.
