TL;DR: IAM enforces real-time access while IGA governs who should have access, how long it should remain active, and whether it still fits policy, according to Keeper Security. The practical lesson is that access control without lifecycle governance leaves privilege creep, audit gaps, and offboarding failures unresolved.
Editorial analysis by NHI Mgmt Group, based on content published by Keeper Security: “Whatâs the Difference Between IAM and IGA?”.
Key questions
Q: What breaks when organisations stop at IAM and skip IGA?
A: They can still authenticate users while leaving entitlement validity unchecked.
Q: Why do IAM and IGA need to be managed together?
A: They solve different parts of the same identity problem.
Q: What do security teams get wrong about access reviews?
A: Teams often treat access reviews as proof of control, when they are really only a point-in-time check.
Practitioner guidance
- Separate runtime enforcement from governance decisions Document which controls belong to IAM, which belong to IGA, and where each system hands off to the other across login, provisioning, review, and revocation.
- Wire access reviews to revocation workflows Make sure certification outcomes trigger actual entitlement changes in downstream systems, not just spreadsheet approval or audit evidence.
- Define lifecycle triggers for joiner, mover, and leaver events Tie role changes and offboarding events to policy-based access updates so access does not persist after the business justification ends.
Bottom line: IAM and IGA solve different problems, and treating them as the same leaves an identity programme blind to entitlement drift.

IAM and IGA are complementary control planes, not interchangeable capabilities. IAM is the runtime enforcement layer, while IGA is the lifecycle governance layer that keeps access aligned with policy over time. Treating them as substitutes leaves a structural blind spot: one control can authenticate and still fail to govern, or govern and still fail to enforce. Practitioners should design identity architecture around both decision points, not either/or purchasing.
A few things that frame the scale:
- 43% of security professionals are concerned about AI systems learning and reproducing sensitive information patterns from codebases, according to the State of Secrets in AppSec.
- Nearly 60% of IT leaders cite restrictive cost and complexity as a weakness of legacy identity governance, according to the 2025 State of Identity Governance Report.
A question worth separating out:
Q: How should teams handle privileged access in an IAM and IGA model?
A: Privileged access needs both runtime enforcement and lifecycle governance. Teams should make sure administrative rights are not just authenticated at login, but also reviewed, justified, and removed when the business need ends. That is especially important for emergency access, shared admin accounts, and other high-risk entitlements.
