Policy firewall for AI agents when Lakera Guard costs money.

Strengths
  • Wire-level proxy means zero code changes to existing agent deployments.
  • YAML policy files with per-scope rules for filesystem, shell, and network.
  • Built-in approval workflow with Slack and webhook notifications.
Weaknesses
  • No Windows binaries, and dashboard requires separate deployment.
  • Emerging category with Lakera, PromptArmor, and MCP security tools already.
