phantom-secrets vs Viper

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.; Viper: VIPER is a powerful and flexible red team platform designed for adversary simulation and cybersecurity assessment. It integrates core tools, an LLM agent, and over 100 post-exploitation modules to efficiently complete red team operations.
