Multi-Tenant Tier (MTT) refers to an architecture in which multiple organizations or clients share a common software environment while maintaining logical separation of data and access.
In clinical research technology, multi-tenant models are common for CTMS, eTMF, eReg, and other platforms used across multiple sponsors or institutions. Strong tenant isolation, role-based access controls, encryption, and audit trails are critical to prevent cross-tenant data exposure. Validation and security testing help ensure shared infrastructure still meets regulatory expectations for confidentiality and integrity of regulated records. A well-governed MTT approach can improve scalability and efficiency while maintaining robust security and compliance controls.
