Microsoft Entra ID, previously known as Azure Active Directory, is Microsoft's cloud-based identity and access management platform. It manages user accounts, groups and sign-in across Microsoft 365 and any other applications connected to it, controlling who can access what within an organisation.
How Microsoft Entra ID works
Every user, group and device in a Microsoft 365 environment is represented within Microsoft Entra ID. When a user signs in to Outlook, Teams or Business Central, Entra ID verifies their identity and applies any relevant security policies, such as multi-factor authentication or Conditional Access rules. Because many third-party applications also support signing in through Microsoft Entra ID, it often becomes the central identity system for an organisation's wider technology estate, not just Microsoft products.
How UK businesses use Microsoft Entra ID
- An IT team enforces multi-factor authentication for all users through Microsoft Entra ID, significantly reducing the risk of compromised accounts from stolen passwords.
- A business uses Conditional Access policies within Entra ID to block sign-ins from unexpected countries while allowing trusted office locations through without additional checks.
- A company configures single sign-on through Entra ID so staff can access third-party SaaS applications using their existing Microsoft 365 credentials, rather than maintaining separate passwords.
- An IT administrator uses Entra ID groups to manage access to SharePoint sites and Teams, automatically updating permissions when an employee changes department.
How Advantage configures Microsoft Entra ID
Advantage configures Microsoft Entra ID security policies, including multi-factor authentication and Conditional Access, as a core part of every cyber security and Microsoft 365 engagement, helping businesses control access without creating unnecessary friction for staff.
Frequently asked questions
Is Microsoft Entra ID the same as Azure Active Directory?
Yes. Microsoft renamed Azure Active Directory to Microsoft Entra ID in 2023 as part of a wider rebrand of its identity and access products under the Entra name. The underlying service and functionality remain the same, with continued development under the new name.
Do I need Microsoft Entra ID if I only use Microsoft 365?
Yes. Every Microsoft 365 tenant is backed by a Microsoft Entra ID directory automatically, even if a business never directly interacts with the Entra admin centre. It manages user sign-in to all Microsoft 365 services behind the scenes.
What is the difference between Microsoft Entra ID and Conditional Access?
Microsoft Entra ID is the identity platform that manages user accounts, groups and sign-in. Conditional Access is a feature within Entra ID that applies rules to control when and how users can sign in, such as requiring multi-factor authentication from unrecognised locations.
