Why it matters
Multi-tenant AI agents can leak one tenant's data to another when isolation relies on fragile application-layer filtering, so defenders building agentic systems need to understand where database-level enforcement fits.
A CockroachDB vendor blog by Quentin Packard argues that data isolation for multi-tenant AI agents must be enforced at the database layer via row-level security (RLS) and geo-partitioning rather than in application code. The piece walks through schema design, RLS isolation policies, tenant-context pipelines, and agent tool implementations, noting AI agents widen the blast radius of a leaked or forgotten query filter and that RLS does not protect against every failure mode.
