Zscaler Data Security Posture Management (DSPM) is specifically designed to discover, classify, and protect data at rest across public cloud environments such as object stores, databases, and other cloud-native services. Zscaler's DSPM solution continuously scans cloud data stores to identify where sensitive data resides, who can access it, how it is shared, and whether it violates corporate or regulatory policies, so security teams gain full visibility into their cloud data landscape and can remediate risks at scale.
In the broader Zscaler Data Protection portfolio, DSPM is highlighted as the capability that extends protection beyond inline traffic to data at rest in SaaS and public clouds, complementing DLP and malware controls that secure data in motion. Cloud Sandbox (option B) focuses on detonating suspicious files to detect zero-day malware; CASB (option C) secures SaaS usage and API-based access; and SSPM (option D) concentrates on assessing and fixing misconfigurations in SaaS applications. None of these options are as tightly aligned to continuous discovery and posture management of public-cloud data at rest as DSPM.
Therefore, the Zscaler technology that enhances cloud data security by providing comprehensive visibility and management of data at rest in public clouds is Data Security Posture Management (DSPM).
