Multi-Tenancy Security
Noun · Security & Infosec
Definitions
The controls and architecture used to keep different customers, business units, or tenants isolated from one another while sharing the same application or infrastructure platform. Multi-tenancy security depends on strong authorization boundaries, data partitioning, logging, and resistance to cross-tenant attacks.
In plain English: Security that keeps different customers or tenants separated on a shared platform.
Example: "The SaaS review focused on multi-tenancy security because all customer workloads shared the same control plane and storage service."
