Requires advanced detection and response capabilities tailored for uncovering, mapping, and neutralizing these hidden identity assets.
- Scoping of the Definition: The critical, missing authorization layer in modern identity security, acting as the necessary bridge to transition the identity stack from passive, read-only visibility to active, granular, and automated governance. It solves the core failure of legacy Identity Governance and Administration (IGA) platforms, which rely on manual, ineffective access reviews.
- Definitional Technology, Feature, and Service Lines:
