Microsoft Entra External ID needs improved support, integration, pricing, security, UI, and customization for medium-sized businesses.
If I could use Azure Front Door with private IP addresses, it would be more beneficial.
It relies on the WAF module where users must configure rate-limiting rules, as it does not automatically sense malicious spikes in traffic.

This is particularly challenging during enterprise agreement renewals, as it's difficult for customers to review costs leading to lengthy negotiations.
Enhanced customizable login options and the ability to use attribute password logins are critical features that are required for Microsoft Entra External ID to gain dominance in the authentication market.

Featured Reviews

Renato Roque - PeerSpot reviewer
Seamless global application delivery with features like efficient load balancing, web application firewall and robust traffic routing capabilities
I find the WAF policy to be exceptionally valuable as it adds a layer of security protection to our applications. I particularly appreciate its load-balancing capabilities as it allows us to manage multiple instances and support a global presence effectively. From a performance standpoint, users can connect to the Front Door, and the load balancer directs them to the nearest origin location. This aspect has been a key factor in enhancing our user experience with Azure Front Door, making it a scalable solution that positively impacts performance.
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.
