## About PromptGuard
PromptGuard is an AI security firewall that protects applications from prompt injection attacks, data leaks, and PII exposure.

It detects and blocks prompt injection attempts, automatically redacts personally identifiable information, and provides comprehensive monitoring through a dashboard. The solution requires zero code changes, developers simply swap their LLM API endpoint to enable protection.
