Strengthening the security of sensitive data
- Identify and Classify Sensitive Business Data : Where is it stored? Who has access to it? How is it being shared and used?

- Strengthen Data Security: Reduce the risks of data overexposure, unauthorized access, and compromise.
- Build Awareness and Accountability: Engage data owners and make them active participants in protecting sensitive information.
