🛡️ RiskOS LLM Guard

🛡️ RAG-augmented LLM output guardrail system. Blocks ~94% of unsafe generations (jailbreaks, PII, harmful content) with <1500ms latency. Integrates LangChain for policy evaluation and Opik for privacy-safe audit logging. Ensuring financial-grade safety and compliance.

What This Solves

Unsafe LLM outputs in a financial or risk context can lead to data leaks, regulatory violations, and reputational damage. Unlike basic keyword filters, RiskOS LLM Guard uses RAG-augmented policy evaluation and semantic classification to detect complex adversarial attacks, prompt injections, and PII exposure before they reach the user.
