Certifaction is a privacy-first digital signature platform built around a Zero Document Knowledge model: documents are hashed and end-to-end encrypted on the client so they can be signed and verified without Certifaction ever seeing their content. It offers Simple, Advanced, and Qualified Electronic Signatures (SES/AES/QES) compliant with eIDAS, ZertES, UETA and ESIGN, delivered through a client-hosted CLI and Local API plus an Admin API for organization, user, role and team-space management, with EU / Switzerland / on-premises data residency and ISO/IEC 27001:2022 certification.
