Companies without a Microsoft license for Entra ID or Azure portal cannot add Azure AD B2C, creating logistical issues for some of my clients who are unable to evaluate the platform.

Microsoft Entra External ID is a stable SaaS, rated 8-10/10, with minimal downtime, reliable except for occasional external issues.
There are compatibility issues occasionally arising with false positives when other security tools are not whitelisted in Microsoft Defender.

It is very resource-intensive, consuming a lot of memory and CPU.
Security Specialist at Prudential Systems Japan

Room For Improvement

Microsoft Defender needs better false positive reduction, integration, cost management, risk scoring, and documentation for small enterprises.
Microsoft Entra External ID needs cost reduction, faster sync, better security, improved SSO, UI, integration, support, and pricing clarity.
This scoring should be for specific industries as well. If I belong to the healthcare industry using Microsoft Defender Vulnerability Management, it should provide me with a risk score and show how I fare against the risk score of my industry.
DGM. Technical Security at a tech services company with 10,001+ employees
A vulnerability I patch within 15 minutes takes 24 additional hours for an update.
information Security and IT Manager at Discover Dollar Technologies Pvt Ltd.

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.
Consultant at Artifield

Overall, every organization wishes for cheaper options, but we look at the security side as well, so we are good for now.
Senior Cloud Security Consultant at MetLife
For non-partners, however, the cost could be seen as higher, between seven to ten.
COO at Floating-Dot Technology LTD
The pricing is reasonable, and it's included in the whole Microsoft E5 bundle, so it's all-inclusive.
Corporate Planner at MISC Berhad
Regarding pricing, the cost seems high for single sign-on, especially for external applications like Oracle.

Microsoft's pricing is complex and difficult to fathom due to a range of different licensing options.

OB
Microsoft Solutions Manager at Self-Employed
Ensures strong threat and vulnerability management with continuous risk assessment
The major priority is identity, which is crucial; we have lots of companies in manufacturing, energy, or various sectors, and it varies from one to another. I assess Microsoft Defender Vulnerability Management as very effective in continuously assessing vulnerabilities without requiring scans. We use automatic investigation and remediation features, safe attachments, safe links, and real-time reports, which are also very effective. For Active Directory, Defender has threat intelligence, and we are using that. The risk-based prioritization within Vulnerability Management affects my ability to manage vulnerabilities, particularly in relation to the Zero Trust Model utilized by our customers. The end-users often do as they please in their systems.
FS
Consultant at Artifield
Offers strong identity unification but needs better customization
Microsoft Entra External ID can be improved with additional features, specifically customizable flexibility and a customizable user interface for the login dialog. Currently, the login dialog has very limited customization options, which only include font styles, colors, text messages, or brand icons. Last month, Entra ID introduced some customizable features in their login dialog, but this does not apply to Microsoft Entra External ID, indicating a significant gap between the two. In theory, Entra External ID can support many external identity providers where custom login dialogs could be integrated, potentially via SSO feature coordination, although I have not yet confirmed this. Hence, 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.
