Data loss prevention (DLP) is a set of products, strategies, technologies, and techniques that ensure end users do not transmit critical or sensitive data outside an organization. DLP also refers to data loss prevention software and other data loss prevention tools that assist network administrators in managing the transfer of data by end users.
Whether it is sent through messaging, email, file transfers, or some other way, information can end up in unauthorized locations. Data loss prevention includes solutions that monitor for, detect, and prevent the unauthorized flow of sensitive data to ensure organizations remain compliant with regulations and maintain customer trust.
Data loss prevention strategies protect organizations against both data leakage and data loss. In a data loss event, something like a ransomware attack causes critical data to be lost. Data leakage is more likely to occur as sensitive information moves between an organization’s critical records systems, for example. Data loss prevention focuses on preventing both types of illicit data transfer outside organizational boundaries.
