Customer Service

Sentiment score
7.3
Auth0's customer service is praised for rapid responses and assistance, though smaller accounts face challenges in accessing support.
Sentiment score
5.6
Microsoft Entra External ID customer service varies, with slow response, staff changes, and better resource access via enterprise contracts.
The support staff are engineers, not just frontline personnel, ensuring expert assistance.
Their support is excellent.
The documentation is very thorough, reducing the need for support.
This represents a weak point, as only the largest companies, with sufficient numbers of seats and employees, can rely directly on Microsoft technical support.
With an enterprise contract, good resources are usually provided, especially in regions like Saudi Arabia or UAE.
 

Scalability Issues

Sentiment score
7.3
Auth0 offers strong scalability with mostly positive user feedback, though some faced issues resolved by a MongoDB structural update.
Sentiment score
8.0
Microsoft Entra External ID is scalable, supports large enterprises well, but may experience latency issues with cloud workloads.
The tool is very scalable and meets our customers' needs.
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.

8.9
Auth0 is praised by users for its stability, high availability, reliable performance, and excellent documentation with high ratings.
Sentiment score
8.2
Microsoft Entra External ID is highly rated for stability, with minor issues often due to external factors, ensuring reliability.
I have not encountered any stability issues with Microsoft Entra External ID.
The stability of this solution is very good.
Unless such major incidents occur, it is stable and reliable.
 

Room For Improvement

Auth0 users seek improved authorization, pricing, customization, administration flexibility, IoT integration, and enhanced Management API for user data.
Microsoft Entra External ID struggles with high costs, slow synchronization, and complex pricing, affecting integration, alerts, and security.
By default, the user profile does not contain the name, first name, or address, which I would expect.
A reduction of 20-25% would be great.
This is particularly challenging during enterprise agreement renewals, as it's difficult for customers to review costs leading to lengthy negotiations.
We have figured out ways to use open-source tools or alternative solutions to address those restrictions that Microsoft has and make things work.
More stability in the platform, fewer changes to authentication mechanisms, and increased integration across platforms to improve usability and security infrastructure are needed.
 

Setup Cost

Enterprise users have mixed opinions on Auth0 pricing; some find it clear and valuable, others see it as costly.
Microsoft Entra External ID becomes costly at scale due to complex pricing and additional integration expenses, despite scalable options.
The cost of the solution itself was cost-effective enough that I didn't even need to compare it with EntraID.
If you need support, then it becomes quite expensive.
Microsoft's pricing is complex and difficult to fathom due to a range of different licensing options.
Regarding pricing, the cost seems high for single sign-on, especially for external applications like Oracle.
 

Valuable Features

Auth0 excels in security, scalability, and integration, offering seamless authentication with extensive customization and compliance with major standards.
Microsoft Entra External ID enhances access management with easy setup, strong security, federated identities, and seamless integration capabilities for widespread adoption.
The most valuable feature of Auth0 is its customizability.
The most important feature for me was the ease of use, as it needed to be easy to integrate into my platform.
It is crucial for hybrid environments, especially for integrating existing on-site infrastructures with cloud-based Active Directory, such as in Office 365 implementations.
The most valuable feature for me is the firewall capabilities.
Primarily Microsoft Entra External ID SSO is valuable as it works with everything when it comes to integration.

Corrado Vigano - PeerSpot reviewer
Solution integrates well with existing systems while being easy to use
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.
