nixis

Nixis is an AI agent firewall designed to enforce real-time governance for AI coding agents like Claude Code, by intercepting and evaluating tool calls against security policies before execution. Its notable features include blocking unauthorized actions such as sensitive file access and destructive commands, along with a user-friendly installation process and an embedded real-time governance dashboard for monitoring and policy testing. This ensures external enforcement of security policies without relying on the AI model's inherent trustworthiness.
