Zero trace. Full answer. --- PromptZero applies Zero Trust principles to LLM interactions. A local, transparent proxy that detects and replaces sensitive data — identities, infrastructure, secrets, client material — in your prompts before they leave your environment, and restores the real values in the response. Never trust the API. Always verify what crosses the boundary. Your data stays home. --- The Problem You use AI to analyze logs, write pentest reports, review code, summarize contracts. Every prompt you send contains real IPs, hostnames, names, credentials, client identifiers, payloads — and every byte of that crosses a boundary you do not control: Vendor contracts and Private-AI SaaS don't fix this — they just shift trust to a different third party. PromptZero handles the boundary locally and lets you verify it end-to-end with the tools you already use (Burp, mitmproxy). --- How It Works Before & After All synthetic values come from IANA-reserved documentation ranges — RFC 5737 ( 198.51.100.0/24 , 203.0.113.0/24 ), RFC 3849 ( 2001:db8::/32 ) and RFC 2606 ( example.com ). The model treats them as opaque non-existent targets, without the \"loopback / internal-lab\" semantics that earlier loopback-flavoured fakes ( 127.0.0.x , .localhost ) carried — see Design notes below. --- What Gets Protected Data Type Real → Synthetic Detection --- --- --- IPv4 address 45.77.12.91 → 198.51.100.1 (RFC 5737) Regex IPv6 address 2001:abcd::1 → 2001","default_branch":null,"files":null,"tree":[],"storefront":"/r/openbashok","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/openbashok/promptzero/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
