Stop choosing between convenience and confidentiality

Traditional e-signature tools expose your contracts to the provider. Subnoto uses confidential computing so sensitive agreements stay private — even during signing.

Total confidentiality

Trusted execution environments and end-to-end encryption protect your data at every stage — including from Subnoto itself.

Secure team workspaces

Browse and search confidential workspaces that only designated team members can access. Send and sign documents quickly.

Compliance built in

Enclaved audit trails, legal evidence downloads, and eIDAS-aligned signatures for seamless compliance.

Everything your team needs to sign

Templates & bulk send

Reuse documents and recipient setups. Send many signature requests from one template using your contact book or a CSV.

Document editor

Prepare PDFs and Word files, place signature fields, and send agreements from one editor.

Passwordless signing

Sign with your fingerprint or Face ID — one tap, zero passwords, and increased security.

Audit trails & evidence

Download signed documents and audit proofs for compliance and dispute resolution.

Team governance

SSO, approvers, viewers, signature order, and role-based access on every envelope.

Integrations

Connect Google Drive, Slack, Discord, Zapier, n8n, and more — or use the API for custom stacks.
