Security and trust

Built so you can stand behind every signature

An electronic signature is only as good as the evidence behind it. This page explains what DocuSend records and how your documents are protected.

Stored in Canada

Documents, signatures and audit records are stored in Montréal (AWS ca-central-1). They are not stored outside Canada.

Encrypted everywhere

TLS protects every connection. Stored files and database records are encrypted at rest with AES-256.

Private by default

Storage is never public. Files are served only to the signed-in sender or through a signer's own link.

One link per signer

Every recipient gets a unique, unguessable 192-bit link tied to their email address. A link cannot be reused for someone else.

Complete audit trail

Each view, consent, signature, decline and void is logged with a timestamp, IP address and device.

Tamper evidence

Originals and sealed PDFs are fingerprinted with SHA-256. Any change, however small, produces a different fingerprint.

What the certificate of completion contains

  • Envelope ID and document fingerprint
  • Sender name and email
  • Each signer's name and email
  • IP address and device for every action
  • Viewed, consented and signed times (UTC)
  • Each signer's adopted signature
  • Signing order used
  • Complete event history

Have a DocuSend PDF?

Confirm it has not been altered since it was sealed. The file never leaves your device; only its fingerprint is checked.
