Unified eDiscovery and Data Loss Prevention in Office 365 allows Tenant Administrators to create, manage, and secure content from a unified console (Office 365 Security and Compliance Center). To date, Tenant Administrators have had to manage Data Loss Prevention for SharePoint, OneDrive for Business, and Exchange in two separate locations, the Office 365 Security and Compliance Center and the Exchange Admin Center respectively. In January 2017, Data Loss Prevention was centralized for SharePoint, OneDrive for Business and Exchange in the Office 365 Security and Compliance Center.
One of the key improvements to eDiscovery in SharePoint Server 2016 IT Preview is the introduction on Sensitive Information Types to eDiscovery. In SharePoint Server 2016 IT Preview Data Loss Prevention is now built into Enterprise Search. It allows you to search for sensitive content in your existing eDiscovery Center, keeping content in place and enabling you to search in real time. SharePoint Server 2016 IT Preview provides a wide range of sensitive information types from different industry segments and geographies, such as credit card numbers, Social Security numbers (SSNs), bank account numbers, and other types, many of which you may already be using to search for sensitive content in email.
