Under the hood
Technical detail behind the capabilities, for IT, security and vendor-risk review.
- Tenant isolation
- PostgreSQL row-level security on every tenant-owned table, with tenant context set per transaction.
- Permission model
- Permissions combine role, resource, action, facility, data type, field and workflow step, evaluated on the server. Self-escalation is blocked.
- Controlled writes
- Regulated changes go through database functions that authorize the actor, append audit events and record outbound integration events in one transaction.
- Audit chain
- Gapless, per-tenant SHA-256 sequence with canonical serialization; audit updates and deletes are blocked; verifiable at any time.
- Integration events
- Stored durably in a transactional outbox in the same transaction as the change, with claim, retry and dead-letter handling, and delivered through Vellum's integration layer.
- Secrets
- Endpoint credentials are held as secret references, never stored in Vellum configuration.
- Hosting and encryption
- Hosted on AWS; data encrypted in transit and at rest. BAA available on request.
