Two Different Layers of the Identity Stack
Identity Governance and Administration (IGA) is a workflow engine. It runs joiner-mover-leaver lifecycle automation, access requests, and certification campaigns: the operational scaffolding that manages the lifecycle of identities once they've been provisioned into it.
IGA's most common failure mode isn't the workflow engine. It's the data underneath it. Access certifications get rubber-stamped against stale data. Connectors break silently. Somewhere between 20 and 40 percent of enterprise identities (local accounts, legacy systems, service accounts, and now AI agents) never pass through IGA at all. Multi-year IGA deployments underdeliver for exactly this reason: organizations with mature IGA, PAM, and AM programs still can't reach a single pane of glass at sustainable cost, even after years of investment.
An IVIP is the data layer IGA was always missing. It makes a certification campaign a review of reality instead of a review of whatever a connector last managed to sync.
