ownCloud provides Universal File Access through a common file access layer regardless of where the data lives – in applications, object stores, on-premise storage or in the cloud. Data is kept where it is while IT is able to manage proprietary information and business risk; leveraging existing data management, security and governance tools and processes. Whether in SharePoint, on a Windows network drive or in cloud storage, users have a single interface from which they can access, sync and share files on any device, anytime, from anywhere–all completely managed, secured and controlled by IT.
