I have a strong relationship with Microsoft since we are one of their best clients in Spain.
The skill level of the support staff is also questionable.
Azure Key Vault's technical support by Microsoft Azure is very good.
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.

Azure Key Vault's scalability, seamless regional integration, and suitability for all business sizes receive high praise despite some dependency concerns.
Sentiment score
6.0
Microsoft Entra External ID offers scalable security for large enterprises, with distinct policies and strong performance despite some latency issues.
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.

Room For Improvement

Azure Key Vault needs better key rotation, mobile access, integration, interface, cost, vendor support, and disaster recovery features.
Microsoft Entra External ID needs improved support, integration, pricing, security, UI, and customization for medium-sized businesses.
My security area wants to rotate passwords every day, every week, or every month, depending on the services.
One of our certificates was not getting deployed, and during that time, the support team was unsure and had to connect with the back-end team for assistance.
The skill level of the support staff is also questionable.
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

Azure Key Vault is seen as affordable with a pay-as-you-go model, though pricing opinions vary among users.
Microsoft Entra External ID pricing is complex, potentially costly, but scalable, benefiting from Azure expertise and existing subscriptions.
I would classify it as low priced.
The pricing of Azure Key Vault is nominal, not that expensive.
We are planning to buy protection for Entra.
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

Azure Key Vault offers secure, scalable key management with seamless Azure integration and comprehensive access control for enhanced security.
Microsoft Entra External ID enhances security, management, and user experience through integration, single sign-on, and adaptive authentication features.
All secrets are in the Key Vault, and access is managed by the integrated management in ITT, which Azure provides to the services.
It also helps me increase my security posture and assists with regulatory and compliance requirements.
Since implementing Azure Key Vault, I have observed that instead of storing plain values, we can store them securely as and when required.
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.
The detailed monitoring and reporting in Microsoft Entra External ID support compliance efforts effectively.

Rajthilak BS - PeerSpot reviewer
Have addressed compliance challenges but still struggle with seamless integration of certificate issuance between environments
In terms of Azure Key Vault improvements, we have to compare the competitor. If we consider AWS, our bank has Microsoft PKI, which is a Microsoft product, for the entire digital certificate infrastructure. Even in the cloud, when it is AWS, the internal certificates are MS PKI. When we had a problem, users had to come to on-premise to get a certificate and import it to AWS Certificate Manager and assign it. We wondered why we could not issue the certificate directly from the cloud for cloud users. There was a simple way in AWS. They have a Private Certificate Authority (PCA) and Amazon Certificate Manager. Private Certificate Authority issues certificates to Amazon services. They also provide Amazon Certificate Manager to store and deploy certificates. These are two neat components - one is an issuer and another is storage and deployment solutions for certificates. With PCA, I can directly enable it and get certificates from AWS itself. AWS can issue SSL/TLS certificates if you enable it directly. If you consider Azure, it is not very clear. Even the naming convention, Key Vault, might not suggest that this is a PKI or certificate manager. You cannot issue certificates directly. They have app certificates and did not have a clear-cut certificate management solution in the cloud when I worked at that time. I am not sure whether they have updated Azure Key Vault as a full-fledged PKI solution now. From what I saw, it was not a full-fledged PKI solution. We are not majorly using Azure Key Vault because it is only for storing secrets. If some solutions can provide guidance on how we can maximize leverage, we can immediately look forward to doing that. We already have some business problems we want to solve. While our primary focus is AWS, many of the services such as ADO are running on Azure, and the secondary services are growing bigger.

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.
