Data Boundary
Strict rules and technical guardrails defining what data an AI system or service can access and process.
Detailed Explanation
A data boundary acts as an isolation layer, ensuring that models, third-party APIs, or microservices only operate on explicitly permitted datasets. Without them, broad access grants lead to accidental data exposure, especially in multi-tenant or LLM-driven environments.
Implementing hard boundaries requires strict network policies, IAM roles, and clear namespace separations rather than relying on application-level filtering.
Why It Matters
Prevents catastrophic data leaks, compliance violations, and LLMs hallucinating responses using cross-tenant PII.
Common Failure Mode
Practical Example
Production Manifestation
IAM role restrictions, dedicated VPCs, row-level security in PostgreSQL, and separate database schemas for different tenants.
Frequently Asked Questions
What is Data Boundary in short?
Strict rules and technical guardrails defining what data an AI system or service can access and process.
What is the most common failure mode?
An AI agent reads a shared document repository and accidentally leaks client A's roadmap to client B because the data boundary was just a soft UI filter.
