Data Security Posture Management (DSPM) tools are designed to help organizations visualize, monitor, and manage the security of their data in the cloud. These tools help ensure that data is properly classified, protected, and compliant with relevant regulations and standards. DSPM tools typically provide capabilities like identifying and managing sensitive data, assessing security risks, and ensuring data security posture is aligned with best practices.
The other options are not the primary focus of DSPM tools:
Firewall management relates to network security rather than data security.
User activity monitoring is more about identity and access management or security information and event management (SIEM).
Encryption is important for data protection but is not the primary function of DSPM, which focuses more on data visibility and management.
