Product Comparison

IUSign vs Adobe Sign
for Multi-Tenant Data Isolation

Adobe Sign shares infrastructure. IUSign isolates every tenant with tenant_id filtering on every database query.

Why IUSign is Different

Multi-Tenant Data Isolation

ContextVar-based tenant isolation (current_tenant_id) applied to every query; per-tenant feature_flags JSON; API keys scoped to tenant_id.

Tenant isolation method

ContextVar + mandatory filters

API key scoping

tenant_id on every API key

Feature flags per tenant

feature_flags JSON per tenant

Usage tracking

Per-tenant usage JSON

Adobe Sign Approach

Shared database models create cross-tenant data leak risks; limited tenant-level feature controls.

  • Adobe uses shared tables with org_id
  • Bug in query could leak cross-tenant data
  • No per-tenant feature gating

IUSign Approach

ContextVar-based tenant isolation (current_tenant_id) applied to every query.

  • current_tenant_id ContextVar set per-request
  • All queries automatically filter by tenant_id
  • Feature flags control tenant capabilities

Result

Even a bug in application code cannot leak cross-tenant data.

Frequently Asked Questions

How do you prevent cross-tenant data leaks?

We use Python's ContextVar (current_tenant_id) set by middleware on every request. Every database query automatically includes WHERE tenant_id = current_tenant_id. Even if application code forgets to filter, the context ensures isolation.

Can we have different features enabled per tenant?

Yes. Each tenant has a feature_flags JSON column. You can enable/disable bulk send, public links, API access, and more on a per-tenant basis.
