Blind Vault delivers secure signing, audit trails, and role-based access without exposing secrets.
Blind Vault is a secure signing SaaS built for teams that need strong security, compliance, and reliable auditability without exposing sensitive document data.
Keys and sensitive information stay protected while workflows stay simple for operations teams.
Track every action with immutable audit history to support legal, risk, and governance processes.
Use APIs and SDKs to integrate signing into existing systems without re-architecting your stack.
Upload documents, set roles and rules, and sign with zero-knowledge protection while every step is captured in the audit trail.
Define roles, set approval rules, and keep keys private while every step is auditable.
Blind Vault keeps signing keys protected and never exposes sensitive document secrets. Zero-knowledge architecture, strict access controls, and encrypted workflows help your team sign with confidence.
Access is enforced with role-based permissions, policy rules, and tamper-aware controls so each signer only sees what they are authorized to view. Data is protected in transit and at rest to support enterprise-grade security posture.
Integrate trusted Swisscom signature services into your document flows. Configure signature levels, automate approval steps, and keep a consistent signing experience inside Blind Vault.
Teams can route signatures to the correct trust level, combine internal approvals with qualified signatures, and keep complete traceability across the full signing lifecycle. This makes compliance workflows predictable and easy to operate.
Every action is recorded with timestamped, verifiable logs. Track who viewed, approved, signed, or rejected each document to support compliance, investigations, and operational transparency.
Audit entries can be reviewed by legal, compliance, and operations teams to resolve disputes quickly and prove process integrity. The result is a defensible history for every document transaction.
