Identity and access management (IAM) is a practice that’s been in enterprises for decades, but what it means and how you manage it has changed drastically. As organizations continue to embrace hybrid and cloud-first models for technology, the need for a secure, scalable, and intelligent cloud-first identity platform has never been greater.
Enter Microsoft Entra ID, the evolution of Azure Active Directory (Azure AD). Azure AD was released in 2013 as a re-imagined and cloud-first identity platform. It has continued to evolve and has emerged as a leading cloud identity provider. Azure AD was renamed to Entra ID in 2023 to indicate Microsoft’s commitment to multicloud and multiplatform capabilities, as well as removing the confusing reference to Active Directory in its name.
If your organization still relies on legacy identity systems, or hasn’t yet explored the full capabilities of Entra ID, this guide is for you. In fact, if you’re using Microsoft 365 (M365), including services like Exchange Online for email, you’re already leveraging Entra ID since M365 uses Entra ID behind the scenes. Unlike traditional AD, Entra ID is a cloud-native solution that offers modern security features and seamless integration with cloud and hybrid environments. In the sections that follow, we’ll explore what Entra ID is, how it differs from Azure AD and legacy AD, and discuss how adopting its full capabilities can elevate your organization’s security, efficiency, and readiness for the future.
What is Entra ID?
First, it’s important to clarify a common misconception: Azure AD was never simply “Active Directory in the cloud.” From its inception, Azure AD was designed as a modern identity provider for cloud and web environments, fundamentally different from traditional AD in both architecture and purpose.
Active Directory (AD), officially known as Active Directory Domain Services (AD DS), is a directory service based on the LDAP protocol. First launched in 2000, AD remains widely used, but it was built for a pre-cloud era focused on on-premises environments.
By comparison, Microsoft Entra ID is a cloud-based identity and access management platform designed to help organizations securely manage user and device identities, authentication methods, and user access to applications and resources. It serves as the backbone for identity in Microsoft 365, Azure, and thousands of third-party apps, as well as being an identity provider for any modern app that needs authentication.
At its core, Entra ID enables:
- User identity management across cloud and on-premises environments
- Authentication and secure access to resources
- Integration with Microsoft 365, Azure, and other enterprise platforms
- Support for hybrid identity scenarios, including synchronization with on-premises Active Directory
Who Should Consider Microsoft Entra ID?
Entra ID is ideal for organizations that:
- Are moving toward hybrid or cloud-first environments
- Rely heavily on Microsoft ecosystems like Microsoft 365, Azure, and Intune
- Need robust identity governance and access control
- Want to enable their employees to be productive wherever they are working
Whether you’re a small/mid-sized business or a global enterprise, Entra ID offers the flexibility, scalability, and security needed to manage identities.
What Makes Microsoft Entra ID Different from Azure AD?
Azure AD was just the cloud directory service, but Entra ID is part of a broader family of Microsoft Entra products, simply called Microsoft Entra. This includes products like:
- Microsoft Entra ID: Formerly Azure AD – the topic of this article and the core cloud-first identity platform from Microsoft. It provides advanced access controls and AI-powered insights for your entire identity landscape.
- Microsoft Entra ID Governance: An advanced identity governance service with features like entitlement management, lifecycle workflows, and access reviews to ensure users have the right access at the right time.
- Microsoft Entra External ID: A combined product offering identity management for external users, whether business-to-business (B2B) or business-to-customer (B2C). The B2C capability is a customer identity access management (CIAM) solution, previously offered as a standalone product under Azure AD B2C, now consolidated into the Entra External ID umbrella.
- Microsoft Entra Verified ID: A decentralized identity solution that enables organizations to issue and verify digital credentials, helping users prove their identity securely without sharing unnecessary personal information.
- Microsoft Entra Internet Access: A secure web gateway (SWG) that provides secure, identity-aware access to internet resources and SaaS applications. It helps organizations protect users as they connect to the internet by enforcing conditional access policies, inspecting traffic for threats, and integrating with Entra ID controls.
How Does Microsoft Entra ID Integrate with On-Premises Active Directory?
One of Entra ID’s strengths is its ability to bridge the gap between traditional on-premises AD and modern cloud identity systems. Using tools like Entra Connect Sync or Entra Cloud Sync, organizations can synchronize user accounts, passwords, devices, and group memberships between environments.
This hybrid approach enables:
- Consistent identity management across cloud and on-premises systems
- Secure access to both legacy and modern applications
- Secure remote work from anywhere for your users who don’t always have to be in the office
- Easy enablement of cloud-first capabilities without having to remove your years of investment in using and managing Active Directory
Key Features of Microsoft Entra ID

Microsoft Entra ID offers a rich set of features designed to meet the needs of modern organizations. These capabilities go beyond basic authentication, providing intelligent, adaptive, and secure identity management across cloud and hybrid environments.
Here are some of the standout features:
Conditional Access Policies
Entra ID enables organizations to define granular access policies based on user context, device health, location, and real-time risk level. This ensures that only the right users, under the right conditions, can access the right resources, from the right locations and devices.
Multi-Factor Authentication (MFA)
MFA is built into Entra ID, allowing organizations to require additional verification steps beyond passwords. This significantly reduces the risk of unauthorized access due to compromised credentials. In fact, Microsoft claims that correctly enabling MFA can prevent 99.9% of account compromise attacks.
Passwordless Authentication
Entra ID supports modern authentication methods such as Windows Hello for Business, FIDO2 security keys, and Microsoft Authenticator. These options improve user experience while enhancing security, taking MFA a step further by preventing the use of a password altogether.
- NOTE: This doesn’t mean users don’t have passwords; they just don’t always use them.
Identity Protection
Using AI and machine learning, Entra ID continuously monitors sign-in behavior to detect and respond to suspicious activity. Risk-based conditional access policies can automatically block or challenge risky sign-ins or lock down user accounts when there’s a high likelihood of compromise.
Workload Identities
Beyond managing human users, Entra ID also supports workload identities — the identities assigned to applications, services, and automated processes that need to authenticate and access resources. Securing these non-human identities is increasingly critical as organizations expand their use of APIs, microservices, and automation.
App Registration and Management
Entra ID supports app registration and integration using modern standards like SAML, OAuth2.0, and OpenID Connect (OIDC). Whether you’re using SaaS, off-the-shelf, or custom applications, Entra ID enables secure single sign-on and centralized access control. There are wizards to help you configure SAML and OIDC apps, especially with some of the well-known and popular apps out there.
User Provisioning and Lifecycle Management
Automate user onboarding and offboarding with integrations to HR systems and SaaS apps. Entra ID ensures that users have the right access from day one—and that access is removed when no longer needed or updated when users move within the organization.
External Identity Support
Entra ID makes it easy to collaborate securely with partners, vendors, and customers through B2B and B2C identity models, including support for federated identity providers.
These features work together to create a secure, scalable, and intelligent identity platform that supports both operational efficiency and regulatory compliance.
