Data Loss Prevention (DLP) refers to a set of tools and strategies used to identify, monitor, and protect sensitive data across an organisation. The purpose of DLP is to prevent unauthorised access, misuse, or transmission of critical information. This usually involves policies and technologies that help detect potential data breach or loss incidents and block them proactively. DLP solutions are crucial in guarding against both internal threats, such as accidental or malicious actions by employees, and external threats like cyber attacks. They typically function by classifying sensitive data, monitoring data access and usage, and ensuring encryption of critical information to secure it against unauthorised exposure.
