Show HN: Dapto – Real-Time Firewall for AI Prompts and Responses (opens in new tab)

Most companies are excited about GenAI, but scared to use it.

Why? Because they have no control over what the AI sees, says, or shares.

We kept seeing this problem in enterprise GenAI rollouts. Tools like GPT or Claude are getting embedded into dashboards, chatbots, and workflows, but there are no guardrails in place.

So we built Dapto. A drop-in firewall that sits between users and the model. It intercepts every prompt and response, blocks prompt injection and hallucinations, masks PII and sensitive content, and adds full logs, metadata, and risk scoring.

It works out of the box with OpenAI, Claude, Gemini, Ollama, and LangChain. No need to modify your model or application.

Here’s a short demo: https://youtu.be/dxFb7Q12gcw

We’re looking for feedback, early pilots, and brutal honesty.

Would this fit into your stack?
