One of the predominant use cases that companies have is to enable file sync and mobile access to file share data that lives behind the corporate firewall without the need for a VPN and without reconfiguring permissions whilst using Active Directory or LDAP for authentication.
In many cases this is done for compliance or security reasons or perhaps because there has been a large investment in internal storage that has yet to be realised.
Accessing files over CIFS/SMB network over VPN using a mobile network is possible but access can be patchy, clients apps limited and it is often extremely slow.
The Storage Made Easy enables this using its built in CIFS connector. This blog post will step through how to cloud enable Windows file shares.
