Data discovery is the process of locating specific subsets of data from unstructured and structured data sources. It is essential to pinpoint what data lies in business repositories and where. Data discovery goes hand-in-hand with data classification, which is the process of sorting different types of data based on its sensitivity and vulnerability. Sensitive data discovery and classification are distinct processes in their own right, essential for locating and securing business-critical data.
