Data Loss Prevention (DLP) refers to a set of technologies, policies, and practices designed to prevent sensitive data from being accessed, shared, or leaked outside an organization - either accidentally or intentionally. DLP solutions monitor data in use, in motion, and at rest, identifying confidential information such as financial records, personal details, or intellectual property. When potential risks or unauthorized activities are detected, DLP tools can block transmissions, alert administrators, or enforce security policies. This helps organizations comply with regulations, protect their reputation, and reduce the risk of data breaches.
