PromptGuard

1 review

PromptGuard is an AI security firewall that protects applications from prompt injection attacks, data leaks, and PII exposure. The platform operates as a proxy between applications and LLM providers, analyzing requests in real-time before they reach the model. 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. PromptGuard works with OpenAI, Anthropic, Groq, and Azure OpenAI, adding minimal latency overhead while providing enterprise-grade security.
