Secure LLM Context Firewall
Build middleware that enforces strict separation between user messages and system-owned memory or provider context before requests reach the model. The product would sanitize forged delimiters, preserve channel integrity, and reduce prompt-injection risk for teams shipping AI agents in production.
これが重要な理由
You are wiring together an agent that stores memory, passes provider metadata, and streams replies back into your product. Everything looks fine until hidden context starts surfacing in the visible conversation or gets written back into history as if the user said it. At that point, your trust boundary is gone. You are no longer sure whether the model is responding to the user, to internal memory, or to a forged block that imitates your own framework format. Existing open-source fixes are partial and uneven, so you end up writing custom guards around every step of the request lifecycle just to feel safe enough to deploy.
- · Engineering teams building AI agents, copilots, and chat workflows that inject memory, retrieval output, or provider-side metadata into model prompts.向けに構築。
- · 最も可能性の高い収益化モデル: SaaS subscription。

MVPの範囲 · 1～2週間
- Implement a lightweight request proxy that accepts chat payloads and rewrites trusted context into a separate internal structure
- Build delimiter and forged-block detection for common memory tag patterns
- Add a simple policy file for allowlist and blocklist behavior
- Create a minimal SDK for Python applications to route prompts through the proxy
- Record blocked events and rewritten payload summaries in a basic dashboard
- Add adapters for two popular agent frameworks and one direct provider API path
- Support response-side sanitization before logs or persistence are written
- Implement replay tooling to compare original and sanitized payloads
- Add team settings for strict mode versus monitor-only mode
- Launch a hosted beta with self-serve onboarding and sample integrations

失敗する可能性がある理由
自己反論 — 最も重要な信頼のシグナル
- 1If major model providers and frameworks quickly ship native channel separation, the product could be compressed into a low-value utility.
- 2Security-conscious teams may decide they cannot trust an external proxy with sensitive prompts and will build in-house instead.
- 3The issue may feel urgent to advanced builders but not broad enough among mainstream AI app teams to support a large standalone business.
エビデンスの概要
AIがこのインサイトをどのように統合したか — 逐語的な引用はありません
Multiple participants described the same underlying failure: memory or provider context is being treated as if it were part of the user message. Several comments focused on forged delimiters, sanitization points, and the lack of a hard channel boundary. The discussion also shows engineers are already patching around the issue manually, which suggests real cost and urgency.
