In multi-tenant architecture, multiple customers share infrastructure while their data remains logically separated. Isolation is enforced through access controls, separate encryption keys, and query-level restrictions.
Single-tenant deployment provides physical separation at higher cost.

Why it Matters?
Isolation is the control that matters most when a legal vendor serves opposing parties in the same litigation, which is common for widely adopted platforms. A firm should be able to state that its matter data is not reachable from another tenant's environment, including through search, analytics, and AI retrieval. Isolation failures in AI systems are a newer risk, since embeddings and indexes derived from one tenant's documents must be scoped the same way the documents are.
