Suresh Kumar Subramaniyan - PeerSpot reviewer
Has supported secure access but still lacks full coverage for external identity challenges
The user experience is acceptable, but Microsoft Entra External ID is not a full-fledged IGA solution. We use different products for complete Identity Governance Administration. Microsoft Entra External ID is suitable for small-scale enterprises implementing identity lifecycle management since most have Active Directory. However, there are several challenges. The out-of-the-box connector has limited features for applications, requiring us to build scheme connectors. While small-scale enterprises can benefit from Microsoft Entra External ID's Identity Governance solution, large-scale enterprises might need different tools from leading market vendors such as SailPoint or Saviynt. Customers face particular challenges with contractor and B2B accounts. Microsoft Entra External ID isn't a complete cloud-based account solution, as it must handle internal employees and collaborate with internal Active Directory. There are delays in the identity lifecycle process, especially for contract partners during onboarding and off-boarding. This might be due to back-end syncing with Active Directory. B2B account removal and provisioning take considerable time. Access governance, particularly access certification for guest users, is time-consuming. Multi-factor authentication enforcement also presents challenges for external users.
