The Order of Chartered Accountants has advised against using email to transfer sensitive data, as messaging services are not always secure. Thanks to Voltn's secure sharing link, we have been able to stop this practice and comply with their 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 benefit from 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.
Can I combine multiple extensions on my Voltn account?
Yes, there is no limit. Each extension is activated and billed independently, according to your changing needs.
Do all extensions work with both 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.
