Identity Governance and Administration, or IGA, is the discipline that manages identity lifecycle, access requests, approvals, reviews, and access policy oversight at scale.
Identity Governance and Administration, or IGA, is the discipline that manages identity lifecycle, access requests, approvals, reviews, and access policy oversight at scale. In plain language, it is the part of identity security that tries to make sure the right people get the right access for the right amount of time, with evidence and accountability around those decisions.
IGA matters because organizations rarely struggle only with sign-in. They struggle with access sprawl, inconsistent approvals, stale entitlements, and weak visibility into who can reach important systems.
It also matters because identity risk grows with organizational complexity. The more applications, departments, contractors, service relationships, and privileged roles an organization has, the more important governance becomes. Without it, access decisions become hard to explain, hard to review, and easy to forget.
IGA appears in joiner-mover-leaver processes, role design, access request workflows, Access Review, Privileged Access Management, and Segregation of Duties oversight.
Teams use IGA to connect identity systems to HR changes, ticketing workflows, approval chains, and compliance evidence. It sits above basic login technology and asks whether the organization can govern access decisions consistently, not just authenticate users successfully.
An employee transfers from sales to finance operations. IGA workflows remove sales-specific application access, route new finance access through the proper approvers, and schedule future reviews for high-risk entitlements so the new permissions do not become invisible over time.
IGA is not the same as an Identity Provider. An identity provider mainly handles authentication and federation. IGA focuses on how access is requested, approved, reviewed, and governed.
It is also different from Single Sign-On. Single sign-on improves the login experience. IGA improves how organizations manage access decisions and accountability across systems.
