This year marks 25 years of Active Directory (AD) —a technology that has shaped enterprise IT like no other. Since its launch with Windows 2000, AD has been the foundation of identity and access management, enabling organizations to securely manage users, devices, and policies at scale.
Even in the era of cloud and Zero Trust security, Active Directory remains as relevant as ever. It has evolved alongside enterprise needs, seamlessly integrating with Azure Active Directory (now Entra ID) to support hybrid environments and modern security frameworks.
From Group Policy and authentication protocols to domain services and seamless hybrid integration, AD has empowered IT professionals for decades. It continues to be the backbone of identity management for businesses worldwide.
As we celebrate 25 years of AD, one thing is clear—its legacy of trust, security, and innovation is far from over.
