Multi-tenant

A SaaS architecture where multiple customers share the same instance, with strict data isolation per customer.

Full definition

Multi-tenant is a SaaS architecture where the same software instance serves many customers (tenants), with each tenant’s data strictly isolated from the others. Zaffre HRM enforces multi-tenancy at the data layer — every model that holds tenant data has a required `company` ObjectId, and every query filters by the authenticated user’s company. Cross-tenant data leakage is structurally prevented.

Multi-tenant in practice
