Obsign

Data and security

Security built in, not switched on

These are properties of how Obsign is built, present on every account and every record by default, not options a customer has to remember to enable.

Two-factor on every account

Mandatory MFA with no opt-out, re-checked at the moment of every dispatch signature. A new session always re-checks the second factor, and access tokens are short-lived.

Tenant isolation

Every read and write is scoped to one organisation by row-level security in the database, and exercised by adversarial cross-tenant tests.

Tamper-evident audit

An append-only, hash-chained log of each audited change, verifiable on demand; any alteration is detected and the exact record named.

Upload checks

Every upload, internal or counterparty, is checked at the door: its bytes must be a PDF, PNG or JPEG whatever the file claims to be, it is checked against known malicious signatures, and anything flagged is rejected and never stored. A stored file that is not marked clean is never served. Scanning is a checkpoint in the pipeline, not a judgement on the document's contents.

Private document storage

Documents live in private storage, served only through short-lived signed links, with every download checked against its recorded sha256.

Guarded counterparty uploads

Accepted only through single-use expiring links, stored without trusting their content type, and never advancing a consignment without human review.

EU data residency

Customer data is stored in the EU (Ireland), with the application served from the UK.

No patient data

By design: there is no patient record in the system, and nothing in the workflow asks for one.

Subprocessors

Obsign relies on three subprocessors: a managed database, authentication and storage platform; an application hosting platform; and a transactional email service (which never receives document files, permit balances or ledger records). Their names, locations and current attestations are listed in the subprocessor schedule supplied with your agreement, and on request from access@obsign.co.
