phantom-secrets vs shellgate

phantom-secrets: Phantom protects sensitive API keys and credentials when working with AI coding agents by replacing real secrets with scoped placeholders. It uses an authenticated local proxy to inject configured authentication values into API requests, preventing agents from directly accessing or exposing actual secret values.; shellgate: Shellgate acts as a secure gateway between AI agents and your infrastructure, ensuring agents never directly access sensitive credentials like API keys or SSH keys. It enforces granular access control, logs every request, and intercepts dangerous commands for human approval, significantly enhancing the security and audibility of AI agent operations.
