Deaddrop is a web based secure file transfer appliance. Deaddrop is used for transferring files between single persons or groups of persons as easily as possible. It is designed from the ground up with security in mind. Operating system, sub systems, web server and web applications are all hardened. The Usability and awesome security features were key design properties built-in from the beginning when we developed Deaddrop.

Only by having an appliance one has the control over file imports/exports into an organization. The Deaddrop virtual appliance allows you to have a policy compliant way to transfer information, to have security controls in place that you configure and control.

Use cases include having Deaddrop
