Anyone may perform the following activities:

Drop-off
Drop-off (upload) a file for a Vario user (email verification required).
Pick-up
Pick-up (download) a file dropped off for you.
 
Vario users: you may login with your username and password and send files to anyone, in or out of Vario.
Non-Vario users: you cannot log in, but can still send files to Vario users if you know their email address. Start by clicking the "Drop-off" button.
Vario users who wish someone outside Vario to send them files, can make it a lot easier for them by logging in and clicking "Request a Drop-off". That saves the other person having to prove who they are. The request created will be valid for 7 days.
 
Vario Secure File Transfer Service is a service to make it easy for you to move files, including large files up to 20.0 GB, in and out of Vario.
 
How secure is Vario Secure File Transfer Service?

Files are automatically deleted from Vario Secure File Transfer Service 14 days after you upload them.
