What is DAG (Data Access Governance)?

Data Access Governance (DAG) is a data security technology that allows enterprises to gain visibility to sensitive unstructured data that exists across the organization, and to enforce policies controlling access to that data.


Unstructured data consists of human-generated files (spreadsheets, presentations, PDFs, etc.). Traditionally, sensitive data was relatively well-protected in structured systems of applications. However, in modern businesses, an increasing amount of sensitive data is included in unstructured formats. This unstructured data often finds its way into storage solutions that are far less secure, such as file shares, collaboration portals (such as SharePoint), cloud storage systems (such as OneDrive or Box) or email.


DAG helps organizations first gain visibility to this unstructured data, no matter where it resides, and then helps enforce policies to better govern its content, ensuring availability only to users that should have access to it. DAG can complement a data loss prevention (DLP) program.
