Target audienceGDPR-sensitive companies, organizations and enterprise teams in the DACH region looking for a centrally manageable solution with German hosting, SSO, automatic user provisioning, MDM rollout and email signature management - as well as individual professionals via the free Lite plan and the affordable Premium plan

oneVcard is a product of oneVcard GmbH and the overall winner of this comparison with 92 out of 100 points. The platform combines digital business cards (QR code, Apple and Google Wallet, NFC cards) with a central team and admin console, more than 20 integrations, an open REST API and dedicated email signature management.

Its top ranking is underpinned by a consistently high profile: GDPR (94), enterprise integration (92), team and admin management (92), feature scope (92), value for money (90) and German-language support (90). This means oneVcard leads not only the overall ranking but also the pure GDPR category.

This detail page assesses the provider by the same disclosed criteria as all others in the test field - including its openly named weaknesses.

Strengths

Its own ISO 27001-certified data center in Nuremberg; hosting and development exclusively in Germany, with no transfer to third countries - plus a data processing agreement (DPA) under Art. 28 GDPR, an external data protection officer, daily backups, 2FA and regular penetration tests
Complete enterprise provisioning: SSO via SAML 2.0, Microsoft Entra ID/Azure AD and Google Workspace with automatic user provisioning (SCIM-style via Entra ID/HR sync) as well as MDM rollout via Microsoft Intune/Entra (e.g. Wallet/app distribution)
More than 20 integrations (Entra ID, Google Workspace, SAP, Personio, BambooHR, Salesforce, HubSpot, Zoho, Dynamics 365, PipeDrive, Make.com, Zapier and others) plus an open REST API in the Enterprise plan and a central team/admin console with roles and permissions
Dedicated email signature management as a standalone product: central Outlook/Microsoft 365 signatures with an officially certified Outlook add-in and HR-based population - going beyond the plain business card
Cheapest entry point in the test field: Lite permanently free, Premium a paid plan in euros - plus German-language support, 850+ customers in DACH/EU and a 99.5% SLA in the Enterprise plan

Weaknesses

Barely any independent, platform-verified user reviews: on G2, Capterra and Trustpilot there are only a few ratings for oneVcard - here international providers such as Blinq and HiHello are considerably more visible
Teams and Teams Enterprise prices are calculated individually and not publicly listed - transparent list prices are only available up to the Premium plan

Data protection & server location

On data protection, oneVcard achieves the highest GDPR score in the comparison with 94 points, and this can be cleanly justified. Operations take place in its own ISO 27001-certified data center in Nuremberg; hosting and development take place exclusively in Germany, and no transfer to third countries occurs.

As a result, neither data nor development lies outside the German legal framework - a difference from providers that build on US hyperscalers (AWS, Google Cloud, Azure). A data processing agreement (DPA) under Art. 28 GDPR is available on request, and an external data protection officer (Prof. Dr. Eberhard Schott) is appointed.

Added to this are daily backups, two-factor authentication and regular penetration tests. This combination of an own certified data center, consistent operation in Germany, and contractual as well as organizational safeguards is exactly what German and European procurement processes require - and the reason why oneVcard leads the pure GDPR category.

The only qualification: oneVcard does not hold a SOC 2 certification, which is mainly required in US-oriented procurement; for the DACH and EU region, ISO 27001 is the authoritative proof.

Enterprise readiness & integration

For enterprise use, oneVcard brings a complete enterprise package (enterprise integration 92, team admin 92). For single sign-on, SAML 2.0, Microsoft Entra ID/Azure AD and Google Workspace are supported; automatic user provisioning is handled SCIM-style via Entra ID or an HR sync, so that onboarding and offboarding can be controlled directly from the identity or HR system.

For device rollout, an MDM path via Microsoft Intune/Entra is provided, for example to distribute Wallet objects or the app. More than 20 integrations cover the common enterprise ecosystem - including Entra ID/Azure AD, Google Workspace, SAP, Personio, BambooHR, Salesforce, HubSpot, Zoho, Dynamics 365, PipeDrive, Make.com and Zapier; in the Enterprise plan, an open REST API is additionally available.

A central admin console with role-based permissions, CSV/bulk import, analytics, lead scanner and multilingual support rounds out the package. A unique selling point is the dedicated email signature management as a standalone product: central Outlook and Microsoft 365 signatures via an officially certified Outlook add-in, populated from HR data.

The Teams Enterprise plan adds white-label, a dedicated account manager and an SLA with 99.5% uptime. More than 850 companies across the DACH region and the EU use the platform.

Verdict: oneVcard

oneVcard is the overall first place in this comparison with 92 out of 100 points and at the same time leads the pure GDPR category (94). The lead rests on hard arguments: its own ISO 27001-certified data center in Nuremberg, hosting and development exclusively in Germany with no third-country transfer, complete enterprise provisioning (SSO via SAML 2.0, Entra ID and Google Workspace with automatic user provisioning and MDM rollout), more than 20 integrations including a REST API, dedicated email signature management, and the lowest entry price in the test.

More than 850 companies in the DACH region and the EU already use the platform. To place things honestly: independent, platform-verified user reviews (G2, Capterra, Trustpilot) are so far barely available for oneVcard - here international providers such as Blinq and HiHello are more visible, and anyone who relies heavily on external reviews should check these additionally.

Likewise, Teams pricing is only stated on request. For GDPR-sensitive companies in the DACH region looking for German hosting, a certified data center, deep Microsoft/Google integration and German-language support at the best price, oneVcard is the obvious choice.
