Data Loss Prevention (DLP) is a cybersecurity strategy that employs a set of tools and processes to ensure that sensitive or critical information is not lost, misused, or accessed by unauthorized users. DLP solutions work by identifying, monitoring, and protecting data in three states: in use on endpoints, in motion across the network, and at rest in data storage. By enforcing granular security policies, these systems can detect potential data breaches or exfiltration attempts and automatically respond by blocking the action, encrypting the data, or alerting administrators, thereby helping organizations protect intellectual property and comply with data privacy regulations.
