Secure AI System Built in a customer onboarding assistant

Quick answer

Treat the onboarding assistant as a privileged agent: map who can talk to it, what tools it can call, and what customer data it can see. Reduce prompt-injection and data-leakage risk by separating untrusted user text from system instructions, grounding actions in allowlisted tools with least privilege, and blocking sensitive fields from prompts and logs. Add runtime checks—injection detectors, tool-argument validation, PII redaction, and human approval for high-risk actions—then verify with red-team tests before widening access.
