SaaS Entitlement Governance: A Reproducible Model for Detecting and Reclaiming Over-Provisioned Access at Enterprise Scale

Abstract

Software-as-a-Service (SaaS) applications have revolutionized information technology service consumption and delivery, garnering substantial adoption among enterprises. Nevertheless, the ease of onboarding – frequently expediting the process to oblivion – often results in excessive and obsolete entitlement provisioning. While traditional entitlement management practices—implementing governance structures, processes, and technologies—address these issues, the sheer number of applications, along with the lack of central governance bodies, recommends a detection-and-reclamation model instead. Automated SaaS entitlement governance requires only a scalable, enterprise-wide data architecture to record access requests. Such an architecture, combined with entitlement and usage metrics, provides everything necessary to operationalize the model at enterprise scale. When an application is subject to governing controls, risk and compliance teams possess the tooling and information to verify data and inform relevant stakeholders. Specifically, these teams can conduct entitlement overprovisioning checks and escalate as appropriate. Consistent overprovisioning check results can inform reclamation decisions and facilitate periodic maintenance tasks. A reproducible model, rooted in the logic of access entitlement overprovisioning, guides the detection of temporary access entitlement provisioning in SaaS applications with low-volume datasets. When access is granted for a specific task and subsequently revoked, these temporary provisions are suitable for governance board requests. The model can therefore guide the operationalization of entitlement governance within enterprise companies and likewise serve as a reference point for any critical SaaS service.
