Voltn, the file 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 users and 2,000 clients protect their data with NetExplorer.

We are Voltn.

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

Our vision as a digital player.

Voltn was born from a real-world 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 focus on doing one thing well: file sharing and storage, with the high standards of a developer that controls 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 guarantees 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.

Sovereign hosting

Your files remain in our own data centers in France, out of 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.
