sproof

sproof is Europe's modular platform for digital signatures and identity verification, built to deliver eIDAS-qualified electronic signatures without sending documents outside the EU. The Salzburg-based company offers a standalone cloud app, a developer API, and deep Microsoft 365 integrations so teams can sign inside the tools they already use.

The platform supports Advanced and Qualified Electronic Signatures with full audit trails, reusable workflows, SSO and user management, batch signing, and white-label customization. An eID Hub verifies identities from more than 170 countries, and native plug-ins for Microsoft Teams, SharePoint, and Word turn everyday Office documents into legally binding e-signed files.

Key benefits:

• Qualified e-signatures with eIDAS legal equivalence to handwritten signatures
• eID Hub covering 170+ country-level identity schemes for global onboarding
• Microsoft 365 integration for signing inside Teams, SharePoint, and Word
• API and white-label options for embedding signatures in any product
• Batch signing and signature validation for enterprise document workflows

sproof GmbH is headquartered in Salzburg, Austria, with all data processing inside the European Union and explicitly no third-country data transfers. The platform is ISO 27001-certified, GDPR-compliant, FDA 21 CFR Part 11 certified for life sciences, and IÖB-certified for use by Austrian public administration.
