Microsoft Entra ID Connect

Secure identity synchronisation between on‑premises and cloud.

Microsoft Entra ID Connect Overview

Microsoft Entra ID Connect (formerly Azure AD Connect) is the identity synchronisation tool that links your on‑premises Active Directory with Microsoft Entra ID in the cloud.

It allows businesses to maintain a single, consistent identity for users across local systems and cloud services such as Microsoft 365. User accounts, passwords, and group memberships remain aligned, reducing administration effort and improving security.

When implemented correctly, Entra ID Connect enables seamless sign‑ins, supports hybrid working, and forms the foundation of a secure Microsoft cloud environment. When implemented incorrectly, it can lead to duplicate accounts, sign‑in issues, or unexpected changes in Entra ID.

Our Entra ID Connect service ensures your identity synchronisation is designed, deployed, and maintained correctly.
