What is Entra ID?

Entra ID is Microsoft's cloud-based identity and access management (IAM) platform that provides a comprehensive and scalable solution for managing user identities, authentication, authorization, and security across your enterprise's applications and services. It’s designed to help IT managers effectively manage access to both cloud and on-premises resources.

A few key components and features of Entra ID include:

  • Identity Management: Entra ID offers a centralized identity management solution that allows organizations to create, store, and manage users, groups, and devices via a single location. It supports user provisioning and deprovisioning, single sign-on (SSO), and password management.
  • Authentication: Entra ID supports multiple authentication methods, both single-factor (password-based) and multi-factor (MFA). MFA can use a combination of factors like text messages, phone calls, or mobile app notifications to verify user identity. Additionally, it supports standards like SAML 2.0, OAuth 2.0, and OpenID Connect (OIDC) for secure authentication with third-party applications.
  • Authorization: Entra ID uses role-based access control (RBAC) to grant permissions to users and groups based on their roles within the enterprise. This ensures that users have access to only the resources they require for their job function, enhancing security and compliance.
  • Directory Synchronization: Entra ID Connect is a tool that synchronizes on-premises Active Directory with Entra ID, providing a hybrid identity management solution. This allows for a seamless authentication experience for users, regardless of whether they are accessing on-premises or cloud-based resources.
  • Conditional Access: Entra ID's Conditional Access policies provide granular control over resource access, based on factors like user location, device compliance, and risk level. IT managers can create policies to enforce MFA or block access for certain high-risk scenarios.
  • Security and Compliance: Entra ID includes several features to help enterprises maintain security and compliance. Identity Protection uses machine learning to detect and prevent suspicious activities. Access Reviews enable periodic reviews of user access, ensuring that users have the appropriate permissions. Private Link provides private connectivity between Entra ID and on-premises networks. Finally, Entra ID Domain Services (Entra ID DS) enables the use of traditional on-premises AD features in the cloud.
  • Application Integration: Entra ID offers seamless integration with a vast array of third-party cloud and on-premises applications, including Office 365, Salesforce, and Google Workspace. It supports custom application integration via APIs and SDKs, allowing organizations to incorporate Entra ID's features into their own applications.
