Data Loss Prevention (DLP) is a security technology that helps organizations protect sensitive data from unauthorized access, use, or theft. DLP solutions monitor and control the flow of sensitive data, both within an organization and across its network boundaries, to prevent data breaches and ensure compliance with relevant regulations and standards. 

DLP solutions can be deployed in a variety of ways, such as network-based, endpoint-based, or cloud-based, to meet the specific needs of an organization. The goal of DLP is to provide organizations with the visibility and control they need to protect sensitive data while allowing users to continue to work with the data they need to perform their jobs effectively.
