The hidden weakness of the tools you already use

Try for free

SharePoint: powerful, but at what cost?

Scenario
The deployment was expensive, the configuration requires a specialist, and no one on the team really knows where to save what.
Result
Underutilized investment, poorly governed data, 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 get things done faster.
Result
Sensitive files circulating outside the IT perimeter, with no traceability or revocation options.

Your documents under US jurisdiction

Scenario
Hosted by providers subject to the Cloud Act or FISA, your documents can be subpoenaed by U.S. authorities without your knowledge.
Result
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, in either France or Luxembourg, depending on your preference, within Tier 3+ and Tier 4 compliant data centers with replication across two separate sites.

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.
