Data loss prevention (DLP) software, also known as data leak prevention software, is used to secure control and ensure compliance of sensitive business information. A key component of DLP solutions is distribution control, which ensures users do not send private information outside of corporate business networks. Security staff and network administrators set business rules that determine who can view, change, and share confidential data. DLP tools often control data on both the network and endpoint level to ensure policies remain consistent across the company. These tools are used to ensure the protection of data and prevent leaks by internal sources.
There are overlaps between DLP tools and some governance, risk & compliance (GRC) software, but these tools are specifically geared toward data control. DLP solutions are also used alongside backup software, but as a complement to the software rather than a replacement.
To qualify for inclusion in the Data Loss Prevention (DLP) category, a product must:
Monitor data storage and sharing for compliance
Allow administrative control over data governance
Detect data leaks or misuse
Facilitate data identification and discovery
