Users faced a learning curve with Microsoft Entra External ID but gained productivity and returns despite higher costs.
It has led to cost savings as well as time savings because I can use a single solution for all applications.
Companies can leverage it for setting up external identities without needing to develop their own solutions.
In terms of return on investment, prior to using this product, our company managed our own mail server with all internal authentication happening on premises, resulting in a ROI in the thousands every year.
 

Customer Service

Sentiment score
7.5
Opinions on Microsoft Defender for Identity support vary, highlighting responsiveness, but issues include delays, contact challenges, and false positives.
Sentiment score
4.3
Microsoft Entra External ID customer support is mixed, with inconsistencies in response times, accessibility, and communication effectiveness.
Generally, the support is more effective than other providers like Oracle.
The quality of support is very good, but troubleshooting can take time due to complex setups and the need to provide many logs.
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.
The support for business applications, infrastructure support, and Entra has been mostly positive with highly skilled technicians.
The documentation is very thorough, reducing the need for support.
 

Scalability Issues

Sentiment score
7.9
Microsoft Defender for Identity efficiently integrates and scales globally, supporting diverse organizational needs within Microsoft’s ecosystem effectively.
Sentiment score
7.0
Microsoft Entra External ID is praised for scalability and security but criticized for limited authentication options and increased latency.
In a Microsoft-centric organization, especially with Azure infrastructure and Office 365, Microsoft Defender for Identity is scalable.
This is one of EID's weak points compared to Azure AD B2C, which offers customizable authentication options, including attribute and password combinations.
End-user workloads experience increased latency in a cloud environment compared to on-premises resources.
Microsoft Entra External ID is quite scalable, and I would rate its scalability between eight and nine out of ten.
 

Stability Issues

Sentiment score
7.2
Microsoft Defender for Identity is highly reliable, with minimal incidents, seamless operation, and consistent ratings between seven and nine.
Sentiment score
5.7
Microsoft Entra External ID is rated highly for stability, reliable and glitch-free except during major disruptions like cloud incidents.
Microsoft Defender for Identity is quite robust and built on Azure hyperscale infrastructure, with a 99% availability.
We do not see any issues with the stability of Microsoft Defender for Identity.
Having recently started using it, reliability is affirmed, but manual investigation is often performed to verify if alerts identified by auto-remediation are accurate.
I'd rate the stability of the Microsoft Entra External ID as a 10.
The stability of this solution is very good.
I have not encountered any stability issues with Microsoft Entra External ID.
 

Room For Improvement

Microsoft Defender for Identity users seek improved cloud integration, user-friendly features, better support, and streamlined processes for enhanced threat management.
Microsoft Entra External ID struggles with high costs, limited features, and slow synchronization, needing better integration and UI improvements.
If Microsoft could develop a feature that indicates when impossible travel is caused by VPN connections, it would prevent unnecessary password resets and session disruptions, especially for VIP users in organizations.
One improvement I would recommend is the integration of an admin application within Teams, allowing easy access to attack information on a mobile platform.
Reducing false positives is something we've been working on with Microsoft.
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.
I would like to see a more detailed alert system that provides a summary of why alerts are generated, who is generating them, and the reasons behind it.
 

Setup Cost

Microsoft Defender for Identity is cost-effective with E5 licenses despite complex pricing and competitive against other security solutions.
Microsoft Entra External ID pricing is complex and potentially expensive, with varying costs and limitations on specific licenses.
If they can reduce the costs, organizations will be happy, and it will compensate for using the Azure environment, which is more expensive on the infrastructure as a service side.
Ensuring a fair price according to market standards.
From an organization perspective, using E5 licenses is value for money, especially if Azure and Office 365 are already in use.
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.
The cost can be a factor for Microsoft Entra External ID, but in general, it offers a scalable and efficient solution compared to deploying individual solutions.
 

Valuable Features

Microsoft Defender for Identity integrates with Azure to offer comprehensive threat detection, identity protection, and advanced real-time security insights.
Microsoft Entra External ID simplifies integration, enhances security with federated identities, and supports seamless hybrid environments and efficient user management.
We receive an advance report of risky users, allowing us to take preemptive action before an attack causes damage to organization details.
The most valuable feature is its hybrid artificial intelligence, which gathers forensic data to track and counteract security threats, much like the CSI series in effect.
The advanced threat protection is one of the strengths of Microsoft Defender for Identity, as it utilizes user and entity analytics and can detect indicative attacks.
It is crucial for hybrid environments, especially for integrating existing on-site infrastructures with cloud-based Active Directory, such as in Office 365 implementations.
EID unifies workforce users with external business partners, which is a very strong feature.
Microsoft's reliability in providing a clear roadmap for the solution is very important, especially at a time when cybersecurity is a risk in every company.

The fact that it is quite integrated into the entire Microsoft environment makes it quite easy to use. Furthermore, Microsoft's reliability in providing a clear roadmap for the solution is very important, especially at a time when cybersecurity is a risk in every company. The solution is easy to reuse and not difficult to find expertise for in the market because it is widespread. It is gaining attention even from partners and from the market on the offering side. This serves as a good starting point for customers who can develop internal competence on the solution. Additionally, the presence of reliable partners who know the solution and can provide internal knowledge is the best aspect for them.
