Agent Credential Proxy and Secrets Isolation Layer

C7/10March 8, 2026

WhatA proxy layer that sits between AI agents and sensitive credentials, granting scoped, auditable access to secrets without ever exposing raw keys to the agent runtime.

SignalMultiple commenters are alarmed that even sandboxed agents retain full read access to SSH keys, API keys, and credentials. One commenter highlighted a project (nono.sh) that adds a proxy to keep credentials out of scope, and others noted that prompt injection means you can never fully trust the agent itself. The need is clear: agents need to use credentials without seeing them.

Why NowPrompt injection attacks against AI agents are proven and unsolvable at the model layer, making infrastructure-level credential isolation the only reliable defense as agents go full-auto.

MarketEvery enterprise and developer using AI agents with access to production systems; $1B+ secrets management market (HashiCorp Vault, 1Password) expanding into agent-specific use cases. Gap: existing secrets managers weren't designed for untrusted AI agent runtimes.

MoatIntegration depth with agent frameworks plus audit trail data creates switching costs; trust/security reputation compounds over time.
