Two overlapping clouds

Azure Active Directory and Azure Active Directory B2C are both cloud-based identity and access management solutions from Microsoft, but they serve different purposes. While Azure Active Directory (AAD) is designed to manage access to enterprise resources, Azure Active Directory B2C (AAD B2C) is geared towards managing customer identities in a business-to-consumer (B2C) scenario. In this article, we will explore the differences between the two solutions, their features and capabilities, pricing, security considerations, use cases, integrations, and best practices for managing user identities in the cloud.

Understanding the differences between Azure Active Directory and Azure Active Directory B2C

Azure Active Directory is a comprehensive identity and access management solution that provides single sign-on (SSO) for cloud and on-premises applications, conditional access policies, multi-factor authentication, user provisioning, and more. It can be used to authenticate and authorize users for Microsoft services like Office 365, Dynamics 365, and Azure, as well as non-Microsoft services like Salesforce, Dropbox, and Amazon Web Services (AWS). Azure AD also supports federation with other identity providers like ADFS, Okta, and Ping Identity.

Azure Active Directory B2C, on the other hand, is a separate service built on top of Azure AD that focuses on managing customer identities for B2C applications. It provides a customizable sign-up, sign-in, and profile management experience for end-users, as well as social identity providers such as Facebook, Google, and LinkedIn. AAD B2C supports user journeys that allow you to define the steps a user needs to take to complete a specific task, such as resetting their password or verifying their email address. These journeys can be customized using HTML, CSS, and JavaScript. AAD B2C also provides integration with marketing automation platforms like Marketo and Eloqua, as well as customer relationship management (CRM) systems like Salesforce.

One key difference between Azure AD and Azure AD B2C is the pricing model. While Azure AD is included in most Microsoft subscriptions, Azure AD B2C is a separate paid service that charges based on the number of monthly active users. This makes it a more cost-effective solution for businesses that only need to manage a small number of customer identities, but may not be the best choice for larger enterprises with a high volume of users.

Which one is best for your organization? A detailed comparison

Choosing between Azure Active Directory and Azure Active Directory B2C depends on your organization’s needs. If you’re an enterprise that needs to manage employee access to corporate resources, then Azure AD is the way to go. It provides many features out of the box that can make user management much easier, such as SSO to hundreds of popular applications, conditional access policies, and multi-factor authentication. Moreover, integrating Azure AD with other Microsoft services like Azure and Office 365 is straightforward and can provide numerous benefits like simplified administration and increased security.

On the other hand, if your organization is a B2C business that needs to manage customer identities, then Azure AD B2C is your solution. AAD B2C provides a rich set of features to manage customer identities, including a customizable sign-in experience, account linking between social identities and email/password-based identities, identity validation, and user journeys. Moreover, AAD B2C provides user data export capabilities, which can be critical if you need to comply with data protection regulations like GDPR.

It’s important to note that while Azure AD and Azure AD B2C have different use cases, they can also be used together in certain scenarios. For example, if your organization is a B2B business that needs to manage both employee and customer identities, you can use Azure AD for employee access management and Azure AD B2C for customer identity management. This can provide a seamless experience for both employees and customers, while also ensuring that each group’s identities are managed appropriately.
