How does it work?

Technically, Lena is a virtual filesystem hosted in the cloud which behaves like a regular drive on your computer. It means that Lena can intercept any attempt made by any user/program to access a file and decide to grant it or not based on access rules and security parameters.

Thanks to cloud technologies, Lena is highly available and storage space will never be an issue.

Lena shows up as a regular drive in your PC and lets you work as usual while offering new features such as:
  • Synchronizing only the files you really use on your computer (other files are downloaded on the fly)
  • Consulting file/folders as they were at any given past date and restoring them (even if they were deleted).
  • Sharing a file/folder instantly with a simple link.
  • Viewing a folder's activity (changes made to files inside the folder) and subscribing to folder changes notifications.
Users with a manager status also have also access to the following features, directly form the file explorer:
  • Managing access & sharing rights.
  • Managing copy and offline usage restrictions.
  • Viewing users activity.
  • Viewing usage statistics.
Lena offers an easy way for administrators to:
  • Manage users and groups.
  • Set globaly security policies.
  • Manage Lena drives.
An optional component, the Lena Enterprise Server, can be installed on-premises on a local server in order to:
  • Bootstrap Lena instantly from your existing files (all the files are available right away in Lena).
  • Keep a full mirror copy of the data in Lena on your own server.
  • Cache on your local network the most used files to enhance performances.
  • Authenticate Lena users against your Active Directory.
