Hey Product Hunt 👋
I'm the maker of Septum.
While building AI systems, I kept running into the same issue:
Sensitive data gets sent to models without control.
So I built Septum — a privacy-first middleware that detects and controls PII before it reaches any LLM.
The goal is simple:
Use AI without leaking sensitive data.
Would love to hear how you're handling privacy in your AI workflows 🙌
