Where is DLP to protect Data at Rest installed?

Data Loss Prevention (DLP) systems are specifically designed to protect sensitive data and prevent unauthorized access or disclosure. When it comes to protecting Data at Rest, it is most effectively installed directly on the system that holds the data.

This approach ensures that DLP solutions can monitor, control, and enforce policies related to the data stored on that specific system. By being deployed on the storage environment where the data resides, DLP can accurately assess the data's state, apply relevant security measures, and prevent any potential leaks or breaches before they occur. This could include encryption, access controls, and monitoring of actions taken on the data.

While other locations, like users' devices or applications, can also benefit from DLP, they do not provide the same level of direct oversight over the data itself as having DLP installed on the system holding the data does. Consequently, centralizing DLP at the data source enhances its effectiveness in safeguarding sensitive information.
