Adobe Acrobat Sign alternative

Adobe brings powerful document signing and a real Teams Live Sign experience. SignumEra extends the model around persistent ceremony authority and evidence.

SignumEra applies the same controlled execution model across Teams, Zoom and asynchronous signing, with explicit finalization and system-of-record return.

Architecture comparison

A ceremony that remains authoritative when the host changes.

Meeting context is useful; the host platform does not become the source of signing authority or the long-term record destination.

Key controls

A ceremony that remains authoritative when the host changes.

Meeting context is useful; the host platform does not become the source of signing authority or the long-term record destination.

Governed ceremony state

Document, recipients, roles, order, evidence requirements and finalization stay authoritative in SignumEra whether execution is live or asynchronous.

Microsoft Entra organizational identity

Use the identity system your enterprise already governs as the organizational authentication anchor.

Phone biometrics and QR device pairing

Signers use phone biometrics and QR pairing. If a signer has no registered phone, they can register it in the signing flow.

Exclusive system-of-record return

Finalized documents and configured evidence return to the explicitly selected system of record. Identity, Teams or Zoom context does not create an additional storage destination.
