Clients have benefited from Data Loss Prevention (DLP) technology within Exchange Online for years. Microsoft is now expanding the functionality to cover data and documents that may be in Office, SharePoint, and OneDrive. Plus they are enhancing the console where the policy rules are managed so that the policy rules for all of the services are controlled in a single location.
Client can continue to use the templates that Microsoft builds to help them stay compliant with regulations like PCI and HIPPA. Severity levels can also be set – so administrators, for example, could have one set of actions that happen if a user tries to send a credit card number externally and another if they are trying to send a file that contains ten or more credit card numbers in it.
DLP not only is for people who are actively trying to share content that they shouldn’t, it is also for people who didn’t notice that there was a company credit card contained 10 emails down in a thread before they forward it to a new distribution list.
