Early Access — Offensive security tool — only for authorized security professionals on systems they have permission to test. Requires extensive local tool installation. Misuse risk is inherent to the category.
Fair rating — This tool is functional but has notable gaps. Review the evaluation notes below before deploying.

Comprehensive AI-assisted pentesting with proper guardrails. Human-in-the-loop for destructive actions and full audit logging show mature security thinking.

Professional penetration testers with proper authorization. NOT for general developers. Requires local installation of security tools (Nmap, Metasploit, etc.).

Automated Scan review. These are observations, not a security certification.

Offensive security tool by design. Human-in-the-loop for destructive actions is a good safety control. Audit logging present.
