AI Guardrails for Production — PII, Jailbreaks, and Human Review
Defense in layers
No single guardrail holds. Stack them: input classification (PII, injection attempts), system-prompt constraints, output validation (format, policy, hallucination checks against retrieved context), and rate limiting per user. Each layer catches what the previous misses.
PII handling for India
Detect and redact Aadhaar, PAN, phone, and UPI IDs pre-retrieval — never let identifiers reach logs or vector stores. DPDP consent capture for stored conversations, with retention windows documented and enforced by scheduled deletion.
Jailbreak reality
Prompt injection via documents (indirect injection) is the underestimated vector — retrieved content carrying instructions. Treat retrieved text as data, never instructions: delimit it explicitly and validate outputs against source grounding.
Human-in-the-loop tiers
Auto-approve low-stakes (FAQs), review medium (refunds under limits), require approval for consequential (payouts, medical, legal). The tier matrix is a product decision, not an engineering afterthought — define it with stakeholders before launch.
