AI Prompt Firewall for Codebases
Build a proxy and developer plugin that intercepts AI coding requests, detects sensitive code or secrets, and redacts or blocks risky content before it reaches external model providers. The product solves the immediate trust gap for teams that want AI productivity without handing over unrestricted repository context.
為什麼這很重要
You want the speed of modern coding agents, but every prompt feels like a quiet data export. As soon as the tool scans your repo, you worry it will ingest proprietary logic, customer details, or credentials that were never meant to leave your environment. Existing secret scanners help after code is written, not at the moment an assistant is about to transmit context. So you end up choosing between productivity and control. A prompt firewall changes that by screening what the agent sees and what actually leaves your boundary, while preserving enough context to keep the assistant useful.
- · 專為 Software teams at startups and SMBs using external AI coding assistants but lacking enterprise-grade data controls. 打造。
- · 最可能的變現方式：SaaS subscription。

MVP 方案 · 1-2 週
- Build a local proxy that accepts chat and code-completion requests and forwards them to one model API
- Add regex and entropy-based secret detection for common key formats
- Create a simple CLI wrapper that captures prompt text and attached file paths
- Store request metadata and redaction events in PostgreSQL
- Ship a minimal dashboard listing blocked and allowed requests by project
- Implement repository path allowlists and deny-lists per project
- Add PII detection for emails, phone-like strings, and customer identifiers
- Support masking sensitive spans instead of fully blocking requests
- Integrate one Git provider to map file sensitivity based on repo folders
- Launch a self-serve team settings page with policy templates
差異化
為什麼這件事可能失敗
自我反駁——最重要的信任度信號
- 1If masking or blocking removes too much context, developers will bypass the tool and return to unrestricted workflows.
- 2Security buyers may prefer broader existing platforms rather than a focused prompt-layer product.
- 3Native provider controls could improve fast enough to make third-party filtering feel redundant for smaller teams.
證據綜述
AI 如何合成此洞察——無原話引用
A large share of the discussion centered on the idea that coding agents can sweep in an entire repository and retain that traffic longer than teams expect. Multiple commenters specifically worried about trade secrets, broad code exposure, and accidental reading of sensitive files. Others pointed to minimizing storage and reducing exposure as the only reliable defense, which supports demand for a software layer that filters prompts before transmission.
