Voltn, the file management expert since 2007

Based in Toulouse since 2007.
Sovereign from the start.

We operate internationally and support more than 300,000 daily users.

Over 300,000 daily users and 2,000 clients protect their data with Voltn.

We are Voltn.

Voltn designs, hosts, and secures file sharing and storage solutions.
One area of expertise, pushed to the limit, rather than a thousand half-mastered skills.

Our vision as a digital player.

Voltn was born from a concrete problem: sending large files without losing control over them. Since 2007, this conviction has remained unchanged; security and sovereignty are non-negotiable.

We don't try to do everything.
We aim to do one thing well: file sharing and storage, with the high standards of a provider that masters every line of code and every server.

Our commitments

‍

End-to-end control

We develop and host our solution ourselves, without outsourcing either the code or the infrastructure.
This control ensures the quality and security of every feature.

Support provided by our own teams

Every client communicates directly with our technical teams based in France. No tickets lost in a chain of subcontractors.

Full control over hosting

Your files remain in our own data centers, located in France or Luxembourg, beyond the reach of the Cloud Act.

A plan that adapts to you

Our solution scales to the size and security requirements of any organization, from SMEs to large enterprises subject to strict regulatory obligations.
