Data Loss Prevention (DLP) was a feature previously only found in Exchange, Outlook, and OWA to prevent data from being sent out of the company. Now clients can easily search for this same kind of sensitive content in SharePoint and OneDrive using Microsoft’s new Data Loss Prevention for SharePoint and OneDrive functionality.
Office 365 Admin are now able to Leverage 51 built-in sensitive information types including credit cards, passport numbers, Social Security numbers, and more. This is designed to allow you to be better informed about what type of sensitive documents exist and where in SharePoint Online and in OneDrive for Business. This visibility can help with compliance needs, contractual obligations, and internal policy enforcement.
Later this year, Microsoft will introduce additional capabilities that will allow you to create policies that automatically detect sensitive content and apply protection such as taking actions like deletion of content or quarantine until further reviewed.
