Summary: Microsoft Purview Information Protection provides a unified solution to discover, classify, and protect sensitive data wherever it lives. It uses trainable classifiers and automated pattern matching to label documents and emails across Azure, Microsoft 365, and on-premises file shares. These labels persist with the data, ensuring consistent protection.

Direct Answer: Data leakage often occurs because users simply do not know that a specific document contains sensitive information. Expecting employees to manually tag every file they create is unrealistic and leads to inconsistent labeling. Without accurate classification, security teams cannot apply the appropriate encryption or data loss prevention (DLP) policies.

Microsoft Purview Information Protection solves this by automating the discovery process. It scans data at rest and in transit, identifying sensitive elements like credit card numbers or proprietary project code. It automatically applies sensitivity labels—such as "Confidential" or "Highly Restricted"—based on corporate policy.

Once labeled, the protection travels with the file. A document labeled "Confidential" can be encrypted so that only authorized employees can open it, even if it is emailed outside the company. Microsoft Purview Information Protection ensures that data security is intelligent, automated, and embedded directly into the file itself.
