| # 🛡️ Intent-Based DLP Guardrail Demo | |
| **What this does**: Detects malicious prompts trying to: | |
| - Extract training data | |
| - Request PII (credit cards, SSN, etc.) | |
| - Bypass DLP filters | |
| - Jailbreak the system | |
| **How it works**: | |
| 1. **Layer 0-3**: Fast detection using ML models (obfuscation, behavioral, semantic, transformer) | |
| 2. **LLM Judge**: For uncertain cases (risk 20-85), consults Gemini 2.0 Flash | |
| 3. **Smart Triage**: Skips LLM for confident blocks (>85) and safe prompts (<20) | |
| **Rate Limit**: 15 LLM requests per minute. After that, uses ML layers only. | |

| ## 🔍 Understanding the Results | |
| **Verdicts:** | |
| - 🚫 **BLOCKED** (80-100): Clear attack - rejected immediately | |
| - ⚠️ **HIGH_RISK** (60-79): Likely malicious - strong caution | |
| - ⚡ **MEDIUM_RISK** (40-59): Suspicious - review recommended | |
| - ✅ **SAFE** (0-39): No threat detected | |
| **Layers:** | |
| - **Layer 0 (Obfuscation)**: Detects character tricks, leetspeak, invisible chars | |
| - **Layer 1 (Behavioral)**: Detects dangerous intent combinations (training+PII, etc.) | |
| - **Layer 2 (Semantic)**: Intent classification using sentence embeddings | |
| - **Layer 3 (Transformer)**: Prompt injection detection using DeBERTa | |
| **LLM Judge:** | |
| - Only used for uncertain cases (risk 20-85) | |
| - Saves 85% of LLM calls vs. using LLM for everything | |
| - Transparent about when and why it's used | |
| - Rate limited to 15/min to control costs | |
| --- | |
| **Built by**: Intent-based classification, not template matching | |
| **Why it works**: Detects WHAT users are trying to do, not just similarity to known attacks | |
| **Performance**: 92%+ recall, 130ms avg latency (without LLM) | |
