 Access Governance is a cloud native identity governance and administration (IGA) service that provides enterprisewide visibility to govern access to cloud and on-premises environments. With an intuitive user experience, dynamic access control, and a prescriptive analytics-driven access review process, it helps customers automate access provisioning, get insights into access permission and cloud infrastructure policy reviews, identify anomalies, and remediate security risks.
