Multi-Tenant Isolation
A foundational security requirement in SaaS architecture that ensures data and operations across different tenants remain invisible and non-interfering when a single system serves multiple independent customers. Implementation approaches include database-level, schema-level, and row-level isolation.
Timeline (last 90 days)
Multi-tenant isolation for enterprise-grade Agents involves not only row-level permissions at the database level but also namespace or collection isolation in the vector store, per-tenant injection of tool credentials, tenant prefixes on cache and session keys, and per-tenant archiving of logs and trace data.
Insufficient isolation granularity leads to security issues such as unauthorized retrieval and cross-tenant leakage via prompt injection.
Multi-tenant isolation means dividing independent data and execution boundaries for different users or organizations within the same Agent service, with common implementations including logical partitioning by tenant_id, independent keys and tool authorization, vector retrieval namespace restriction, and sandbox process- or container-level isolation.
If isolation is done only at the storage layer while ignoring the policy layer, an agent may still reply to customer B's review in customer A's tone, which is a failure mode more subtle and harder to audit than data leakage.
Bedrock Agent Core builds multi-tenant isolation mechanisms into the platform layer, so developers only need to write agent logic targeting a single user to achieve horizontal scaling.
