CentreStack increases workforce mobility by allowing file sharing via cloud and mobile access. However, security permissions are maintained and users have the same experience as file servers. Active Directory and permissions inherit allow for the best integration of existing IT infrastructure's cloud security with cloud mobility. CentreStack improves file servers to allow mobile workers to collaborate and be productive. This includes those who use smartphones and media tablets in addition to their PCs. CentreStack can either improve an existing file server to allow mobile access, or it can migrate existing data and security permissions into a user-defined cloud. The product's goal is to provide a familiar file server experience that allows for greater usability, security, compliance, and data control. Enterprises have the option to preserve their security and compliance by keeping their data on-premise without cloud replication.
