"Enterprise file synchronization and sharing (also known as EFSS and enterprise file sync and share) refers to software services that enable organizations to securely synchronize and share documents, photos, videos and files from multiple devices with employees, and external customers and partners. Organizations often adopt these technologies to prevent employees from using consumer-based file sharing apps to store, access and manage corporate data that is outside of the IT department’s control and visibility."
