TL;DR: Light IGA can automate joiner-mover-leaver workflows and standard certifications, but Omada Identity argues it often leaves cloud control planes, legacy systems, service accounts, and production-adjacent access outside governance. That gap turns identity security into a coverage problem, not a feature problem.
Editorial analysis by NHI Mgmt Group, based on content published by Omada Identity: “Why Light IGA Can't Carry Enterprise Identity Security”.
Key questions
Q: What breaks when light IGA does not cover all critical systems?
A: Governance breaks at the boundary between connected applications and the rest of the estate.
Q: Why do ungoverned service accounts increase enterprise risk?
A: Ungoverned service accounts increase risk because they often hold standing access, are rarely reviewed, and can persist long after the business need has changed.
Q: How do security teams know if business-driven IGA is working?
A: Look for falling revocation latency, fewer orphaned accounts, fewer unused entitlements, and faster completion of access changes after joins, moves, and exits.
Practitioner guidance
- Map governance coverage against critical systems List cloud control planes, legacy ERP, privileged vaults, production-adjacent environments, and service-account stores, then compare them with current connector coverage.
- Reconcile toxic combinations across all access domains Test segregation-of-duties rules across identities and systems that live outside the same workflow engine, especially where approval paths are split between tools.
- Inventory ungoverned non-human identities Find service accounts, contractor accounts, and local application identities that were never onboarded into certification or remediation workflows.
Bottom line: Light IGA can improve routine identity workflows, but it stops being sufficient when critical access sits outside its connector coverage.

Light IGA creates a governance perimeter, not enterprise governance. The core weakness is not that lifecycle automation exists, but that coverage stops where the connector library ends. Once cloud control planes, legacy ERP, privileged vaults, or production-adjacent systems sit outside that perimeter, the organisation no longer has one governance story to explain who approved access and why. Practitioners should treat scope as the first control decision, not a deployment detail.
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: How should organisations decide between Light IGA and Full IGA?
A: They should decide based on governance scope, not feature labels. If the environment needs entitlement catalogues, role engineering, segregation of duties enforcement, or coverage across disconnected systems, lightweight governance will not be enough. If the estate is simple, cloud-connected, and already visible, Light IGA may cover the immediate need while a fuller roadmap is built.
