A Data Loss Prevention (DLP) system provides a content and context based control, it is able to effectively guarantee the prevention of data loss with anticipated and reduced costs. The DLP system’s multilayer inspection and interception engine provide a specific control on a wide range of the data loss paths at a contextual level. It is possible to analyse and apply filters on certain data -on an endpoint- that is transferred to removable and PnP devices, as well as data transferred on computer networks, in order to ensure an additional protection of the confidential data. Thanks to an adequate DPL system, administrators are able to precisely associate users’ rights with their professional roles in connection with the events of data transferring, receiving and storing on company’s computers. A perfect IT environment through a DLP system allows all authorized users to easily and freely perform their activities, whereas all accidental or deliberate attempts intended to perform unauthorized activities are blocked.
