The hidden weakness of collaborative suites

Try it for free

SharePoint: powerful, but at what cost?

Scenario
Le déploiement a coûté cher, la configuration demande un spécialiste, et personne dans l'équipe ne sait vraiment où ranger quoi.
Result
Underutilized investment, poor data governance, and teams bypassing the tool.

 One tool for storage, another for signing, a third for transferring

Scenario
Documents move from one platform to another at every stage of their lifecycle: stored here, signed there, sent elsewhere.
Result
Mounting costs, diverging versions, and an impossible-to-reconstruct audit trail.

Shadow IT thrives on complexity

Scenario
 When the official tool is too cumbersome, teams switch to personal drives and consumer services to work faster.
Résultat
 Sensitive files circulating outside the IT perimeter, with no traceability or possibility of revocation.

Your documents under US jurisdiction

Scenario
Hosted by providers subject to the Cloud Act or FISA, your documents can be subpoenaed by US authorities without your knowledge.
Résultat
 A loss of legal control over your data, incompatible with the requirements of regulated sectors.

FAQ

Where is Voltn Workspace data hosted?

Exclusively in Europe, within Tier 3+ and Tier 4 compliant data centers, with replication across two distinct sites. Voltn manages its own servers: your data never leaves French territory and remains beyond the reach of the Cloud Act. SecNumCloud qualification is currently in progress.

Is electronic signature integrated into Voltn Workspace?

Yes, with the Voltn Workspace + Sign plan. It allows you to send signature requests that comply with the European eIDAS regulation (simple, advanced, or qualified) directly from the platform, complete with workflows, automated reminders, and proof archiving.

Can you co-edit Word, Excel, or PowerPoint documents online?

Yes. Voltn Workspace allows you to create, edit, and co-edit standard office formats (docx, xlsx, pptx) in real time. Version history lets you track every change and restore a previous version at any time.

Is Voltn Workspace an alternative or a complement to SharePoint?

Both, depending on your project. Alternatively, Workspace can replace SharePoint for document management, offering simpler governance, sovereign hosting, and guided migration. As a complement, Workspace works alongside Microsoft 365 via Outlook and Teams connectors and Office compatibility, allowing you to host your sensitive documents beyond the reach of the Cloud Act.

What is a sovereign document management platform?

A sovereign document management platform hosts and processes an organization's documents within a French or European legal framework, free from the reach of extraterritorial legislation such as the U.S. Cloud Act. Voltn develops its solution and operates its own infrastructure in France, ensuring end-to-end control over your data.

What is Voltn Workspace?

Voltn Workspace is a sovereign document management platform, developed and hosted in France. It centralizes document storage, co-editing, sharing, approval, and electronic signatures for organizations within an environment certified to ISO 27001, ISO 9001, and other standards.
