Autonomous AI Security Testing & Self-Repair System
A system that automatically tests voice agents for vulnerabilities, detects failures, generates fixes using GPT-4o, and re-tests until the agent is secure—all without human intervention.

- Project Structure
- Testing Modes
- Configuration
Voice agents are vulnerable to prompt injection, social engineering, and security leaks. This system provides autonomous security hardening through:
- Adversarial Testing - Test agents with malicious inputs
- Failure Detection - Identify security leaks, loops, and policy violations
- AI-Powered Fixes - GPT-4o analyzes failures and generates improved prompts
- Verification Loop - Re-test until secure or max iterations reached
