Data discovery is the process of identifying, cataloging, and classifying all data assets within an organization. This process involves scanning databases, file systems, cloud storage, and other data repositories to locate both structured and unstructured data. By understanding where sensitive data resides, organizations can better manage compliance, security, and data governance. Data discovery tools often use automation and machine learning to quickly find and categorize data, making it easier to protect sensitive information and reduce the risk of data breaches. This is a critical first step in establishing effective data protection strategies.
