There are a number of ways commonly used to move files between systems. One way is to attach a file to a message and email it to the file’s intended recipient. Once at the inbox, the recipient is responsible to break out the file attachment from the message and save the file in a destination folder. Getting a file from machine to machine is easy and convenient since email clients such as Outlook are generally always open on the desktop and no password is needed to place an email with a file attachment into a recipient’s inbox. When using SecureMail from DataMotion, the file is also transferred securely and privately along with the message body.
While this workflow works great for many use cases, many email systems limit the size of a message and its file attachments to 10mb or less. Another use case that limits sending files by email is the need to completely automate getting a file from the sender’s folder on the original file system to the recipient’s folder on their destination file system. It can be clumsy or inconvenient to get the file in an email attachment through that final step of where it actually needs to live. Finally, the very convenience of not needing a password to send a file into a recipient’s inbox can also be a fatal flaw when the recipient can’t allow just anyone to bring a file into their system even if it was securely and privately transmitted.
DataMotion supports the use of SFTP to send or receive files. SFTP is a commonly used protocol that allows for a fully automated file transfer direct from originating file location to destination file location with access granted only to authorized senders. The beauty of DataMotion’s solution is that either secure email or secure file transfer can be used homogenously end-to-end or alternatively, can easily be mixed together in the same transfer. For example, a sender may want the convenience of using DataMotion’s secure email to send a file as an attachment while a recipient may require the automation and secured access of SFTP to receive files, or vice versa. DataMotion supports the use of both SecureMail and SFTP to separately and individually support the needs of sender and recipient.
This is independent of the requirements of how the sender needed the file to be sent or the recipient needed the file to be received.
In my next blog entry, I will survey the various secure file transfer protocols and explain how DataMotion makes use of the SFTP protocol.
