PromptGuardX: Extending AI Security into Files
🛡️ PromptGuardX inspects PDFs before their content reaches an LLM or AI agent, detecting hidden instructions and obfuscation techniques that can enable prompt injection. Integrated into Check Point Threat Emulation, it extracts and normalizes text, locates suspicious instruction regions, analyzes context with fine-tuned classifiers, and returns explainable verdicts and confidence scores. This upstream file-layer protection complements runtime monitoring, access controls and prompt inspection.
