TL;DR: Strong login controls do not stop privilege creep or substitute for recurring access certification, according to RSA Security. Identity programmes need governance to keep entitlement reviews, compliance evidence, and lifecycle changes from drifting.
Editorial analysis by NHI Mgmt Group, based on content published by RSA Security: “Identity Governance and Administration (IGA) vs. Identity and Access Management (IAM): What’s the Difference?”.
Key questions
Q: Why does IAM without IGA create governance risk?
A: Because strong authentication only proves the identity is real at login.
Q: What are the signs that access governance is failing in practice?
A: The clearest signs are slow remediation, repeated rubber stamp access reviews, and missed permissions outside traditional HR linked systems.
Q: How do IAM and IGA work together in an identity programme?
A: IAM provides the operational layer for authentication, authorisation, and provisioning.
Practitioner guidance
- Separate authentication from entitlement governance Map IAM capabilities such as MFA, SSO, and passwordless to login assurance, then assign IGA controls to access approval, certification, and reporting.
- Build recurring access reviews around current role Review entitlements against job function, project assignment, and approval history so excess access is removed before it becomes normalised.
- Tie lifecycle events to deprovisioning workflows Trigger access changes when employees move roles or leave, and apply the same offboarding discipline to service and machine accounts where they exist.
Bottom line: IAM and IGA solve different problems, and treating them as synonyms weakens the identity stack.

IAM and IGA are complementary control planes, not alternative labels. IAM is about proving identity and enabling access. IGA is about governing whether access is appropriate, defensible, and still aligned to policy. When programmes treat them as synonyms, they usually overinvest in authentication while underinvesting in entitlement governance. The result is a control stack that can tell you who got in, but not whether they should still be there.
A few things that frame the scale:
- 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: When should organisations prioritise IGA over IAM in regulated industries?
A: Prioritise IGA when the main challenge is proving that access is appropriate, not merely granting it. That becomes essential in environments handling sensitive personal data, or when audit evidence, recertification, and segregation of duties are required for compliance. IAM still matters, but governance should lead when regulatory scrutiny and entitlement risk are the dominant concerns.
