About the startup
Prompt injection is the SQL injection of AI, and most teams aren't prepared. We built PromptGuard: a drop-in firewall that sits between your app and LLM providers. It automatically blocks prompt injections, redacts sensitive data, and prevents leaks, all with zero code changes. Just swap your base URL. Works with OpenAI, Claude, Groq, Azure. As AI adoption accelerates, companies need this security layer. We're making it simple.
