Uncover prompt injection, insider threats with the Tenable One Model Refusal Detection

This Tenable blog introduces Model Refusal Detection in Tenable One AI Exposure, which treats LLM refusals to risky prompts as early-warning signals to detect prompt injection, insider threats, and adversarial behavior. It summarizes research into refusal types, model variability, and advocates a defense-in-depth approach to monitor and investigate attempts to bypass model guardrails.
