Azure Entra ID vs. Entra ID B2C: A Comprehensive Comparison

In an era where identity and access management are paramount to business resources, Microsoft offers a suite of powerful tools under the Azure umbrella. Among these are Azure Entra ID, otherwise formerly known as Azure Active Directory, and Entra ID B2C (Business to Consumer). While they share some foundational elements, they cater to different needs and use cases. Let’s examine Azure Entra ID vs. Entra ID B2C and their features, uses, and ideal use cases.

Azure Entra ID

Azure Entra ID is a comprehensive cloud-based identity and access management service for employees and internal users. It helps organizations manage user identities, control access to applications and resources, and enhance security through various features. Some of the key features include:

Key Features of Azure Entra ID

  1. Single Sign-On (SSO): This property or feature enables users to sign in once and access multiple applications, both on-premises and in the cloud services, without requiring them to sign in again. It saves time and effort.
  2. Multi-Factor Authentication (MFA): This is a common protection method exercised by many companies, which tends to add an extra layer of security. It requires users to verify their identity using a second factor, such as a phone call or mobile app notification.
  3. Conditional Access: This feature provides fine-grained access control policies based on conditions such as user location, device state, and application sensitivity.
  4. Self-Service Password Reset (SSPR): According to this feature, SSPR allows users to reset their passwords without IT assistance, which reduces the helpdesk workload.
  5. Identity Protection: This uses machine learning to detect and mitigate identity-based threats, such as suspicious sign-in attempts and compromised accounts.
  6. Integration with Microsoft 365: Seamlessly integrates with Microsoft 365, thus providing enhanced security and identity management for Office applications.
  7. Application Proxy: It enables secure remote access to on-premises web applications.

Use Cases of Azure Entra ID

  1. Internal Employee Management: This allows the management of employees to have access to company resources to ensure secure and efficient identity management.
  2. Access Control for SaaS Applications: It provides secure access to third-party SaaS applications used by the organization.
  3. Enhanced Security Measures: By implementing MFA and conditional access policies, businesses are better able to protect sensitive information with Azure Entra.
