About Sproof Sign
sproof is an Austrian-based technology company providing a modular platform for digital signatures and identity verification. The service focuses heavily on European digital sovereignty, positioning itself as a secure alternative to US-based signature providers. It offers a range of tools from a standard web application to deep API integrations, allowing companies to automate contract workflows while maintaining compliance with the eIDAS regulation. The platform supports various signature levels, including Advanced (AES) and Qualified (QES) signatures, and integrates with national eID systems across the EU. A key highlight of the service is its commitment to EU data residency, specifically avoiding US-based data centers to mitigate risks associated with international surveillance laws and ensuring full GDPR compliance.
