As cyber threats grow more advanced, organizations need more than firewalls and traditional password policies to protect sensitive data. Two essential parts of a modern identity security strategy are Identity and Access Management (IAM) and Identity Governance and Administration (IGA). While IAM focuses on verifying identities and enabling secure access to systems, IGA ensures that access rights are appropriate and continuously monitored. The main difference between IAM and IGA is that IAM controls who can access sensitive information, while IGA ensures that this access stays aligned with organizational policies. In simple terms, IAM acts as the “muscle” that enforces access, while IGA serves as the “brain” that defines and governs access policies.
Continue reading to learn what IAM and IGA are, how they differ and why organizations need both to improve their overall security posture.
What is IAM?
Identity and Access Management (IAM) is the framework of policies and processes that ensures only the right users can access the resources they need at the right time. IAM verifies identities, enforces authentication and grants appropriate access across apps, systems and IT environments. Simply put, IAM focuses on access enablement, ensuring employees, partners and verified users can securely access the tools and data they need to do their jobs. IAM typically includes:
- Authentication and authorization: IAM verifies that a user is who they claim to be and determines what they can do once authenticated.
- Single Sign-On (SSO): SSO lets users access multiple apps with a single login, improving productivity and limiting password fatigue.
- Multi-Factor Authentication (MFA): MFA adds an extra layer of security by requiring additional factors beyond a username and password, such as biometric authentication or a One-Time Password (OTP), to reduce the risk of unauthorized access.
- Role-Based Access Control (RBAC): RBAC assigns access rights based on user roles within an organization, ensuring consistent, least-privilege access and preventing unnecessary levels of access. IAM enforces RBAC at runtime, while IGA governs and reviews these role assignments over time.
What is IGA?
Identity Governance and Administration (IGA) adds oversight, accountability and control to an organization’s IAM processes. While IAM enforces access in real time, IGA ensures that access remains appropriate and aligned with internal policies. IGA provides visibility into who has access, what they use it for and how long they should retain it. IGA tools do not replace IAM; they orchestrate and govern access decisions that IAM systems enforce. The main capabilities of IGA include:
- Identity Lifecycle Management (ILM): IGA automates provisioning, modification and deprovisioning as employees join or leave an organization. ILM reduces security risks by ensuring users only have access to what they need.
- Access certifications and reviews: IGA conducts regular access reviews to ensure access remains appropriate, helping to prevent privilege creep.
- Policy enforcement and audit trails: Through policy-based access controls and detailed audit trails, IGA supports compliance audits and internal investigations.
IAM vs IGA: Key differences
While IAM and IGA work together, they serve different but complementary roles within an organization. IAM focuses on managing access, ensuring users can authenticate and interact with what they need in real time. IAM is operational, handling the daily activities of authenticating, authorizing and granting permissions when a user logs in or performs a task. In contrast, IGA manages the identity lifecycle and the policies that govern access, defining who should receive access and why. IGA establishes rules, manages provisioning and conducts ongoing reviews to ensure access remains appropriate.
| Feature | IAM | IGA |
|---|---|---|
| Purpose | Enables secure access | Governs and audits access |
| Main focus | Authentication, authorization and permissions | Identity lifecycle management and compliance |
| Access timing | Controls access at runtime (in real time) | Defines and reviews access in advance; does not enforce runtime access but governs policies used by IAM |
| Compliance support | Operational compliance support (limited governance depth) | Strong support for audits and access certifications |
| Real-time access decisions | Yes, enforces access instantly | No, but influences IAM decisions through policy frameworks |
Why organizations need both IAM and IGA
IAM and IGA are complementary solutions that, together, form a full identity security strategy. While IAM provides operational controls to authenticate users and enforce access in real time, IGA governs those access rights to ensure they’re appropriate and continuously reviewed. Modern identity strategies require both real-time access enforcement and long-term governance, especially in hybrid, multi-cloud and compliance-heavy environments.
These two systems intersect across many identity processes, such as onboarding and offboarding. For example, IGA defines the policies that determine what a user can access, while IAM enforces policies when the user logs in to an app or service. During access reviews, IGA identifies unnecessary or excessive access, and IAM revokes those permissions. Combined, IAM and IGA support zero-trust security through least-privilege access and continuous verification.
Strengthen identity security with KeeperPAM®
Modern security strategies require both the operational controls of IAM and the governance abilities of IGA to keep up with sophisticated cyber threats. When IAM and IGA are used together, users receive the right access at the right time, and every access decision is aligned with internal policies and broader compliance requirements.
KeeperPAM® fits directly into this strategy as a zero-trust Privileged Access Management (PAM) solution, securing credentials, secrets, privileged accounts and endpoints that are commonly targeted by cybercriminals. With secrets management, automated credential rotation, RBAC, privileged session recording and seamless integrations with IAM tools, KeeperPAM helps organizations expand identity security into privileged layers.
Start your free trial of KeeperPAM today to build a modern, zero-trust identity security strategy with both IAM and IGA.
