Microsoft Entra External ID vs. Workspace Tenant

Microsoft Entra External ID vs. Workspace Tenant

Section titled “Microsoft Entra External ID vs. Workspace Tenant”

Microsoft Entra External ID is a component of the Microsoft Entra identity platform designed to manage external identities. It allows organizations to securely collaborate and engage with users outside their organization (partners, customers, and vendors) without the need for creating separate accounts within the internal workspace.

On the other hand, a Workspace Tenant (often referred to as an Entra ID tenant or home tenant) is the central tenant that manages internal users, devices, and applications of an organization, providing full access to Microsoft 365 services, Azure resources, and enforcing policies like Zero Trust.


Understanding the distinction between Microsoft Entra External ID and Workspace Tenant is crucial for implementing a comprehensive identity and access management strategy that balances security with collaboration needs.

MFA RequirementsExternal user verificationInternal user security
Device ComplianceBasic device checksFull device management
Location-Based AccessGeographic restrictionsNetwork-based controls
Risk-Based AuthenticationExternal risk assessmentComprehensive risk analysis

Microsoft Entra External ID:

  • Verify Explicitly: Authenticate external users strongly
  • Least Privilege Access: Grant minimal necessary permissions
  • Assume Breach: Monitor external access for suspicious activity

Workspace Tenant:

  • Comprehensive Verification: Full identity and device verification
  • Granular Access Control: Detailed permission management
  • Advanced Threat Protection: Complete security monitoring

Key Takeaway: Leveraging both Microsoft Entra External ID for external users and Workspace Tenant for internal users creates a secure and collaborative environment that adheres to Zero Trust principles.
