Idea
Policy violation detection tool for LLMs delivering efficient, interpretable compliance monitoring without retraining.
Research Paper
Core Innovation
This paper proposes treating policy violation detection as an out-of-distribution problem by applying activation-space whitening to LLM hidden states, standardizing them to zero mean and unit variance. Using Euclidean norms in this transformed space as compliance scores enables training-free, efficient detection that surpasses existing guardrails and fine-tuned models in accuracy and interpretability.
Why It Matters
Organizations deploying LLMs in regulated sectors face legal and reputational risks from policy breaches. This solution offers a lightweight, scalable way to detect nuanced policy violations without costly retraining or latency, improving oversight and compliance workflows. It enables enterprises to enforce internal policies reliably, reducing risk and operational burden.
Market Size (TAM)
$2–10B TAM for AI governance and compliance tools; $500M–$1B SAM from regulated enterprises adopting LLM oversight. Driven by increasing AI deployment in sensitive sectors and regulatory pressure for transparent AI use.

Research Paper Overview
Training-Free Policy Violation Detection via Activation-Space Whitening in LLMs
Summary
This paper introduces a training-free method to detect policy violations in large language models by transforming hidden activations to a whitened space and using Euclidean norms as compliance scores. It requires only policy text and a few examples, enabling efficient, interpretable, and robust detection beyond generic safety filters. The approach outperforms existing guardrails and fine-tuned models on a challenging benchmark, offering a practical solution for organizational AI governance.
