In a multi‑tenant SaaS environment, you need to ensure that each customer sees only their own data.

This is typically achieved through row‑level security (RLS) in the data model and isolation at the analytics layer.

RLS policies filter queries based on tenant identifiers, while column‑level security can restrict sensitive fields.

Many analytics platforms allow you to define these policies in the semantic layer and then enforce them automatically.

You should also separate tenants’ storage and compute resources where possible to avoid noisy neighbors.

MageMetrics makes multi‑tenancy simpler by suggesting RLS policies during auto‑mapping and by supporting separate warehouse connections for large tenants.
