“With Voltn we share and collaborate easily, in a fully secure, HDS-compliant environment, adapting the access rights, confidentiality and audit trail requirements of each of our assignments to their specific needs.”
Laurence Lahousse
Administrative Manager, Cabinet ALCYON
“The French institute of chartered accountants recommended no longer using email to transfer sensitive data, because email systems are not always secure. Thanks to Voltn's secure sharing link, we were able to stop doing so and comply with that recommendation.”

FAQ
Is the API extension only for technical teams?
No. Developers use it for custom integrations, but our native Outlook, Teams, and Google connectors allow you to take advantage of it without any technical skills.
How do I know which extensions are right for my organization?
Our experts work with you to assess your industry, file volume, and regulatory requirements, then recommend the right combination for your needs.
Can I combine multiple extensions on my Voltn account?
Yes, there is no limit. Each extension is activated and billed independently, allowing you to scale as your needs evolve.
Do all extensions work with Voltn Share and Voltn Workspace?
No. HDS, Private Cloud, Onboarding, and the SecNumCloud commitment apply to both products. Sign, Vault, and Watermark are exclusive to Workspace, as they rely on native features of its collaborative platform.
