Software-as-a-service (SaaS) applications are increasingly storing more sensitive data. Inappropriate management of SaaS applications’ configuration and data and resource access exposes organizations to data breaches, compliance failures, and potential disruptions in business operations. SaaS security posture management (SSPM) solutions allow for configuration management and access anomaly detection and prevention. This report examines the drivers for SSPM adoption; reviews the high-level workings of SSPM, including identity and data protection capabilities; and describes SSPM best practices based on our interviews with customers who have implemented SSPM.
