As organizations adopt cloud applications, remote work environments, and interconnected digital platforms, managing user identities has become an important part of information security. Businesses need to know who has access to their systems, what permissions users have, and how those permissions are managed over time.
Two concepts that frequently appear in modern identity strategies are identity governance and administration and federated identity and access management . Although they are related, they address different aspects of identity and access security. Understanding the difference can help organizations design a more structured approach to managing digital identities.
What Is Identity Governance and Administration?
Identity governance and administration, commonly referred to as IGA, focuses on managing and controlling digital identities and their access rights throughout an organization.
It provides processes and controls for creating user accounts, assigning permissions, reviewing access, and removing access when it is no longer required. The objective is to ensure that users receive appropriate access based on their responsibilities while reducing unnecessary permissions.
IGA can cover several activities, including:
- User lifecycle management
- Access requests and approvals
- Role and permission management
- Access certification and reviews
- Separation of duties
- Identity provisioning and deprovisioning
- Audit reporting and compliance support
For example, when an employee joins a company, IGA processes can help ensure that the employee receives access to the applications required for their role. When the employee changes departments, their permissions can be reviewed and adjusted. When they leave the organization, their access can be removed.
This makes identity governance and administration particularly relevant for organizations that need greater visibility and control over user access.
What Is Federated Identity and Access Management?
Federated identity and access management focuses on allowing users to access multiple applications or services using an identity managed by a trusted identity provider.
Instead of requiring users to maintain separate credentials for every application, federation allows participating systems to trust authentication performed by another identity system.
This approach is commonly associated with technologies and standards such as SAML, OAuth, and OpenID Connect.
For example, an organization may have employees using several cloud applications. Rather than creating separate usernames and passwords for each application, employees can authenticate through the organization's identity provider and access approved applications through that trusted relationship.
Federated identity and access management can therefore simplify authentication while providing organizations with a centralized way to manage how identities are used across connected environments.
Key Difference Between IGA and Federated Identity
The main difference is what each approach is designed to manage.
Identity governance and administration focuses primarily on identity lifecycle, permissions, governance, and access oversight.
Federated identity and access management focuses primarily on authentication and trusted access between identity providers and applications or services.
In simple terms, IGA helps answer:
"Who should have access, what access should they have, and is that access still appropriate?"
Federated identity and access management helps answer:
"How can this user securely authenticate and access a trusted application using an existing identity?"
These functions can complement each other rather than being viewed as competing approaches.
Identity Lifecycle Management
Identity lifecycle management is a major component of IGA. User access can change as people join an organization, change roles, move between departments, or leave.
Without structured lifecycle processes, users may retain permissions they no longer need. IGA helps organizations establish processes for requesting, approving, modifying, reviewing, and removing access.
Federated identity systems can support the authentication side of this process, but they do not necessarily provide the complete governance framework required to determine whether a user should have specific permissions.
Authentication and Single Sign-On
Federated identity and access management is closely connected to authentication and single sign-on.
With federation, a user can authenticate with a trusted identity provider and then access participating applications without repeatedly entering separate credentials. This can reduce password-related friction and create a more consistent authentication experience.
IGA, meanwhile, is less focused on how a user authenticates and more focused on determining whether the user's access is appropriate and properly governed.
Access Reviews and Compliance
Organizations often need to periodically review user permissions. This can be important for internal security policies, regulatory requirements, and audit processes.
Identity governance and administration can provide workflows for access reviews and certifications. Managers or designated reviewers can examine permissions and confirm whether access should remain active.
Federated identity and access management can help enforce authentication policies across connected applications, but governance processes are still needed to determine whether users should have particular levels of access.
How the Two Approaches Work Together
IGA and federated identity can form complementary parts of an identity security strategy.
Consider an employee who needs access to several cloud applications. IGA can determine which applications and permissions are appropriate based on the employee's role. Federation can then allow the employee to authenticate through a trusted identity provider and access those approved applications.
When the employee changes roles, IGA processes can trigger an access review or modify permissions. Federation continues to provide the authentication mechanism for applications that participate in the federated environment.
This separation of responsibilities can help organizations create a more structured identity management environment.
Choosing the Right Approach
The decision is not necessarily about choosing one technology over another. Organizations should first identify their identity and access requirements.
IGA may be particularly relevant when an organization needs stronger control over permissions, identity lifecycle processes, access reviews, and governance.
Federated identity and access management may be particularly relevant when organizations need to connect identities across multiple applications, services, domains, or organizational environments.
Many modern organizations can benefit from using both approaches as part of a broader identity and access management strategy.
Conclusion
Identity governance and administration and federated identity and access management address different challenges within identity security. IGA focuses on governing identities, permissions, and access throughout the user lifecycle, while federated identity focuses on authentication and trusted access across connected systems.
Understanding these differences allows organizations to build identity strategies around their specific requirements. When combined thoughtfully, governance processes and federated authentication can help create a more organized, secure, and manageable approach to digital identity and access.
