What is Identity Governance and Administration (IGA)?

If Identity Management (IDM) is about ensuring the right people have the right access, Identity Governance and Administration (IGA) is about proving it — continuously, consistently, and in a way that satisfies auditors, regulators, and security teams alike.

IGA has emerged as a critical discipline for organizations that need to go beyond basic identity management and establish verifiable control over who has access to what, why they have it, and whether they should still have it.

Understanding IGA

Identity Governance and Administration combines two closely related capabilities:

Identity Administration covers the operational aspects of managing identities: creating accounts, assigning roles, processing access requests, and automating the identity lifecycle. This is largely what traditional IDM addresses.

Identity Governance adds the oversight layer: defining policies that control how access is granted, conducting periodic reviews to ensure access remains appropriate, detecting policy violations, and providing the evidence trail that auditors and regulators demand.

Together, these capabilities form a comprehensive framework that not only manages identities but ensures they are managed correctly, consistently, and in compliance with organizational policies and external regulations.

The core capabilities of IGA

Access request and approval workflows

IGA platforms provide structured workflows for requesting and approving access. Instead of ad hoc emails or tickets, users submit requests through a centralized portal. Requests are automatically routed to the appropriate approvers based on configurable rules — the manager, the application owner, a security team member, or a combination.

These workflows enforce consistency and create an audit trail for every access decision. Every request, every approval, every denial is recorded with timestamps and justifications.

Access certification and recertification

Perhaps the most distinctive capability of IGA is access certification — the periodic review of existing access to confirm it is still appropriate. Managers and application owners receive campaigns asking them to review and either certify or revoke the access assigned to users under their responsibility.

Without certification, access tends to accumulate over time. An employee who changed roles three years ago may still have access from their original position. A contractor whose project ended months ago may still have active accounts. Certification campaigns systematically identify and remediate these situations.

Segregation of Duties (SoD)

Segregation of Duties policies prevent dangerous combinations of access that could enable fraud or errors. For example, the same person should not be able to both create vendor records and approve payments, or both develop code and deploy it to production.

IGA platforms evaluate access requests and existing entitlements against SoD rules, detecting violations before they occur or identifying existing violations that need remediation. This is a critical control for financial compliance frameworks like SOX.

Role management and role mining

Roles are the building blocks of access management. IGA platforms help organizations define, manage, and optimize their role models. Role mining capabilities analyze existing access patterns to suggest role definitions that reflect actual business needs, rather than relying on theoretical models that may not match reality.

A well-designed role model simplifies access management, reduces the number of individual entitlement assignments, and makes certification campaigns more manageable.

Risk-based analytics

Modern IGA platforms incorporate risk scoring to prioritize attention where it matters most. Not all access violations carry the same risk. An orphaned account with read-only access to a non-sensitive application is a different risk than an orphaned account with administrative privileges to a financial system.

Risk-based analytics help security teams focus their limited resources on the highest-impact issues, rather than treating all violations equally.

Audit and compliance reporting

IGA platforms generate the reports and evidence that auditors need: who has access to what, when was it last reviewed, who approved it, are there any policy violations. This transforms audit preparation from a manual, multi-week exercise into a matter of generating reports from a centralized system.

IGA vs. IDM vs. IAM: the relationship

These three terms represent overlapping but distinct concepts:

IDM focuses on the operational mechanics: provisioning, deprovisioning, authentication, directories.
IAM is the broadest term, encompassing identity management, access management, authentication, authorization, and federation.
IGA specifically addresses governance and compliance: policies, certifications, SoD, risk analytics, and audit.

In practice, organizations need all three. IDM provides the operational foundation. IAM extends it with access control and authentication. IGA adds the governance layer that ensures everything operates within policy and provides the evidence to prove it.

When does your organization need IGA?

Several indicators suggest it is time to invest in IGA:

Recurring audit findings related to access management, orphaned accounts, or segregation of duties
Regulatory requirements that demand demonstrable access controls and periodic reviews
Growth in identity volume that makes manual governance unsustainable
Merger or acquisition activity that brings together disparate identity populations and systems
Security incidents traced back to excessive or inappropriate access

The business impact of IGA

Organizations that implement IGA effectively experience measurable improvements:

Audit preparation time decreases significantly as evidence is continuously generated
Access-related security incidents decline as governance controls catch violations proactively
Operational costs decrease as manual review processes are automated
Compliance confidence increases as policies are enforced consistently rather than sporadically

Moving forward

IGA is not a luxury reserved for the largest enterprises. Any organization subject to regulatory requirements, managing more than a few hundred identities, or concerned about the security risks of ungoverned access should be evaluating IGA capabilities.

The question is not whether your organization needs identity governance. The question is whether you can afford the risk of operating without it.
