Microsoft Entra organizational identity
Use the identity system your enterprise already governs as the organizational authentication anchor.
Electronic signature software
E-signature solved the paper problem. SignumEra solves the trust problem.
Move beyond the email-envelope model. SignumEra binds organizational authority, the resolved source-document revision, signer assurance, ceremony policy, finalization and evidence inside one governed execution layer—without forcing the signing platform to become your permanent document warehouse.

Verified signing. Governed execution.Why SignumEra
The signing platform for transactions where context matters.
Use Microsoft Entra for organizational identity, Zoom or Teams for live context when needed, private SignLinks for external participants, and your chosen system of record for the completed record.
Server-authoritative authorization
Rust—not menu visibility—enforces sensitive actions. Owner, Admin, Member and Auditor permissions remain application controls.
Resolved Execution Target
Before Prepare, resolve the source system, document identity, immutable revision marker such as version/eTag, execution content hash and resolution time. A changed source revision requires a new target.
Frozen execution manifest
Freeze the Execution Target, participants and roles, order, ceremony mode, witness rules and finalizer. Material changes require a new revision and manifest.
Governed ceremony state
Document, recipients, roles, order, evidence requirements and finalization stay authoritative in SignumEra whether execution is live or asynchronous.
FIDO2 / WebAuthn passkeys
Cryptographic, device-centric confirmation can strengthen signer and owner actions without making reusable passwords the trust anchor.
Evidence package
Bind document integrity, identity, policy, events, verification, cryptographic proof and configured meeting evidence to the finalized record.
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.
Built in Gibraltar
Verified signing. Governed execution.
Minimize unnecessary long-term document custody and keep the public signing layer focused on controlled execution. 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.
Architecture comparison
Most platforms can capture an electronic signature. Far fewer treat identity, live ceremony control, passkey proof, evidence and record custody as one architecture.
This matrix focuses on controls that matter for high-assurance execution rather than commodity signature capture.
