A sovereign ecosystem, built into every plan.
vBoxxCloud bundles best-in-class European tools for encryption, mail and documents into one seamless workspace. Cryptomator, eM Client and OnlyOffice — included, EU-hosted and GDPR-compliant by default.
Licences included
Pro licences for Cryptomator, eM Client and OnlyOffice ship with every vBoxxCloud plan — no upsell, no per-seat surprise.
100% EU-hosted
Every integration runs on our own infrastructure in the Netherlands and Germany — no transatlantic data hops.
GDPR by default
Schrems II-proof: no CLOUD Act exposure, no SCC paperwork, full audit logs and DPA included.
Seamless workflows
Single sign-on, shared address book and one identity across mail, files and documents.
Cryptomator
Zero-knowledge vaults for your most sensitive files.
Add an extra, client-side layer of AES-256 encryption to any folder in vBoxxCloud. Files and filenames are scrambled before they ever leave your device — not even vBoxx engineers can read the contents.
- Open-source, audited AES-256 encryption
- Works transparently inside your synced folder
- Mobile apps for iOS & Android included
- Recover access with your personal passphrase
eM Client
A premium mail, calendar and contacts client for every team.
Unify mail, calendar, contacts, tasks and chat in one elegant desktop app for macOS and Windows. Bundled Pro licences make eM Client the default mail experience for every vBoxxCloud user.
- IMAP, Exchange, iCloud and Gmail — all in one inbox
- Shared calendars & resource booking
- PGP and S/MIME end-to-end encryption
- Native macOS & Windows apps, fully translated
OnlyOffice
Real-time co-editing for Word, Excel and PowerPoint files.
Open .docx, .xlsx and .pptx files straight from vBoxxCloud and edit them with your team in real time. Full Microsoft Office compatibility, native track-changes and inline comments — without leaving the EU.
- Pixel-perfect Microsoft Office compatibility
- Real-time co-editing with cursors & comments
- Version history synced with vBoxxCloud
- PDF forms, e-signature placeholders & redlining
Three tools. One identity. Zero friction.
The real magic isn't the individual apps — it's how they work together. Mail flows into files, files open in documents, sensitive folders disappear into encrypted vaults.
Sign in once. Work everywhere.
Single sign-on flows your vBoxxCloud identity into eM Client and OnlyOffice. Open a contract from your inbox, edit it live with a colleague and store the signed version — all under the same encrypted account.
- SSO via Azure AD, Okta or Google Workspace
- Shared address book & directory
- One audit trail across mail and files
From draft to signature — without leaving the EU.
Co-edit a proposal in OnlyOffice, attach it to an eM Client email and send it for eIDAS-qualified signature from vBoxxCloud. Every step is logged, encrypted at rest and stored on European soil.
- Real-time OnlyOffice co-editing
- eIDAS qualified e-signatures
- Encrypted Cryptomator vault for the final archive
Shared calendars, shared focus.
Book a meeting room in eM Client, drop the agenda into a shared OnlyOffice document and keep the minutes encrypted in Cryptomator. Your team stays in sync without a single third-party tracker.
- Shared calendars and resource booking
- Inline collaboration on agendas
- Private vaults for HR & legal notes
Every partner, vetted on European ground.
We don't bolt third-party SaaS onto our platform. Every integration is hosted on our own EU infrastructure, contractually bound to GDPR and audited under the same ISO regime as the rest of vBoxxCloud.
