About
Noisegate AI is a privacy-preserving security proxy designed to sanitize inputs and outputs for untrusted AI agents. Built for enterprise software teams, it applies differential privacy and PII redaction before requests reach external LLM endpoints.
Security engineers and developers use Noisegate AI to enforce tool execution policy boundaries and prevent accidental data leakage in automated AI agent applications. By sitting between internal agent tools and cloud model vendors, it provides real-time policy enforcement.
For FutureStack, Noisegate AI belongs in Developer Tools because it serves as privacy-preserving proxy infrastructure for AI agents. It is best for security engineers, developers, and compliance teams.
