Data Leagage Prevention

What is Data Leagage Prevention (DLP)?

Data Leagage Prevention (DLP) describes a strategy to ensure that end users do not send confidential or critical information to recipients outside an enterprise network. The term is also used to describe software products that allow a network administrator to control what data end users can transmit.

How does data leakage prevention work?

Data leakage prevention software products use business rules to classify and protect confidential and critical information so that unauthorized end users cannot inadvertently or maliciously share data whose disclosure could put the business at risk. For example, if an employee attempts to forward a business email outside the corporate domain or upload a corporate file to a Cloud consumer storage service such as Dropbox, the employee will be denied authorization.


The adoption of DLP is being driven by Insider threats and stricter government privacy laws. Some DLP tools can not only monitor and control endpoint activity, but also filter data flows on the corporate network and protect data in motion.
