Secure file sharing and editing with


e-Col for collaboratively achieving common goals
e-Col is Content Collaboration Platform.

It does so by enabling file sharing, file syncing and
collaboratively and simultaneously editing common office documents such as Word*, Excel* and Powerpoint* files.

e-Col instances run on separate servers, usually outside of the client's own IT environment. Clients have complete control over users and their access rights. The IT environment is GDPR compliant.

Users of e-Col may share all kinds of documents (not restricted in file types). Online-editing, however, is limited to Word, Excel, PowerPoint, OpenOffice, and regular Text files (txt, html, etc).

e-Col has been developed to enable online editing of these documents simultaneously with other users of e-Col, or even with guests.

e-Col uses
NextCloud and OnlyOffice in an integrated work space.
