Why MSPs need one tenant per customer

· Sources: Auris glossary freeze 2026-09-17; AEGIS gates.

For MSP ops, one tenant per customer is the hard isolation boundary. Organizations can nest inside a tenant (soft structure) — they are not a substitute for tenant isolation.

FAQ

What is a tenant vs an org?

Tenant: hard security/data boundary (customer). Org: grouping inside a tenant for teams/roles — soft. Don’t conflate.

What does isolation mean for MSP ops?

Blast-radius limits, clearer access reviews, and cleaner offboarding when a customer leaves. Product talk — not a certification claim.
