The term data loss prevention (DLP) in security refers to strategies and technologies aimed at preventing the unauthorized sharing or loss of sensitive information. DLP solutions monitor data usage across networks, endpoints, and in the cloud, identifying potential risks and protecting critical data from breaches. By implementing DLP policies, organizations can ensure compliance with regulations such as GDPR or HIPAA, avoiding significant legal repercussions. Ultimately, DLP is crucial for safeguarding an organization's reputation and maintaining customer trust by securing their sensitive information.
