Identity Governance and Administration (IGA) is a framework of policies, processes, and technologies for managing digital identities and their access rights across an organization, encompassing identity lifecycle management, access request and approval workflows, access certification reviews, role management, and segregation of duties enforcement.
Context for Technology Leaders
For CIOs, IGA addresses the critical challenge of managing who has access to what across increasingly complex hybrid environments. As organizations deploy hundreds of cloud applications alongside legacy systems, unmanaged access accumulates—creating security vulnerabilities, compliance gaps, and audit failures. Enterprise architects design IGA as the governance layer that sits above authentication and authorization systems, ensuring that access rights are appropriate, regularly reviewed, and aligned with business roles and regulatory requirements.
Key Principles
- 1Identity Lifecycle Management: IGA automates the joiner-mover-leaver process, ensuring that access is provisioned on hire, adjusted on role change, and revoked on departure—eliminating orphaned accounts.
- 2Access Certification: Periodic reviews require managers and application owners to certify that user access rights are still appropriate, catching access creep and enforcing least privilege.
- 3Role-Based Access: IGA defines business and technical roles with associated entitlements, simplifying access management and ensuring consistency across the organization.
- 4Segregation of Duties (SoD): IGA enforces rules that prevent toxic combinations of access—such as the ability to both create and approve financial transactions—reducing fraud risk.
Strategic Implications for CIOs
CIOs should invest in IGA as a foundational capability for both security and compliance, recognizing that it reduces audit costs, prevents access-related breaches, and enables faster onboarding. Enterprise architects must integrate IGA platforms (SailPoint, Saviynt, One Identity) with HR systems, cloud applications, and infrastructure to create a comprehensive access governance fabric. The shift to cloud-native IGA platforms supports hybrid environments and scales with organizational growth.
Common Misconception
A common misconception is that IGA is just about provisioning user accounts. While provisioning is a component, IGA's strategic value lies in governance—ensuring that access rights are appropriate, compliant, and continuously monitored. The certification and segregation of duties capabilities are what differentiate IGA from basic identity management.
