Security and trustMulti-Tenant IsolationData Isolation Architecture

Tenant and application isolation

Check both what a caller may do and which records they may access. VeriProof applies several controls; their combined effect depends on the service, operation, identity, and database role.

Scope layers

LayerBoundary
TenantOrganization resolved from the authenticated identity
Role and capabilityActions permitted by the effective system or custom role
ApplicationApplications assigned through role, group, ownership, or explicit scope
Audit engagementAssigned applications and dates for the active engagement
DatabaseService role, grants, query scope, and row policies
PresentationResponse fields and links appropriate for the caller

Privileged paths

Staff, administrative, background, and database operations can require broader access. Document and test each path separately.

A database role that can bypass row policies needs approval, monitoring, and a narrower service boundary.

Validation matrix

Use controlled identities and records in an authorized test environment. Cover:

  • an authorized record;
  • another application in the same tenant;
  • another tenant;
  • an inactive or removed user;
  • each standard role;
  • relevant custom roles and group scope;
  • an expired or unassigned audit engagement; and
  • direct API access without the portal navigation.

Inspect the returned records and confirm that out-of-scope data is absent. A 200 response with another tenant’s records is an authorization failure.

For write operations, check the stored result too. A denied response must not leave an approval, configuration change, or other protected action behind.

Role preview is a presentation aid. Use a real signed-in identity and backend response for authorization evidence.
