Microsoft Entra is a cloud-based identity and access management solution designed to secure access across cloud and on-premises environments through features like conditional access policies, role-based access control, and real-time risk detection using machine learning. It integrates identity protection mechanisms to identify compromised credentials or anomalous sign-in activities, enforces multifactor authentication and passwordless authentication, and provides Zero Trust Network Access via components like Private Access for secure application connectivity. Entra also includes identity governance tools for automated lifecycle management, access reviews, and compliance enforcement, alongside Security Service Edge capabilities such as web content filtering and TLS inspection through its Internet Access module. The platform supports hybrid environments by extending protections to on-premises Active Directory and enables device registration for Conditional Access policies.
