Also known as DLP.

Data is often compared to oil in terms of its potential value. It is like oil in another way: data is easily copied, leaked, and lost. Data Loss Prevention (DLP) is the set of tools, processes and technologies which help organisations better control their data by seeking to prevent loss, misuse, unauthorised access or exfiltration. DLP solutions typically monitor sensitive data, detecting when there are issues around its use by establishing anomalies, and stopping ‘leaks’ by preventing unauthorised copying or transmission.
