METATRON
AI-powered penetration testing assistant using local LLM on linux (Parrot OS)
The Lens
By Erik Loyd, SaaS CEO and former COO/CFO of an AWS Premier Partner.
Updated Jun 2026
METATRON runs penetration tests with a local LLM doing the analysis. Point it at a target and it executes nmap, nikto, whois, and other standard security scans, then feeds the results to an LLM running on your machine for vulnerability assessment and exploit suggestions. Everything stays local, nothing hits the cloud.
Built specifically for Parrot OS (a Linux pen-testing distro), it stores findings in MariaDB and exports reports as PDF or HTML. The LLM integration means you get natural language explanations of scan results instead of parsing raw nmap output yourself. It's essentially a security analyst copilot that runs offline.
Security professionals and pen-testers who want AI assistance without sending scan data to external APIs get the most out of this. Students learning security will appreciate the explanations. Experienced red teamers might find the tool suggestions basic compared to their existing workflow.
The catch: Parrot OS only, which limits the audience significantly. The local LLM quality depends entirely on your hardware, and smaller models give vague or wrong security advice.
Free vs Self-Hosted vs Paid
fully freeFree Tier
Everything. MIT-licensed, fully open source.
Self-Hosted
This IS self-hosted. Requires Parrot OS, MariaDB, Python, and a local LLM. Hardware requirements depend on the LLM you run. Needs a GPU for decent inference speed.
Paid
Doesn't exist.
Completely free and open source. Bring your own hardware for the LLM.
What to do by team size
- Solo
- free if you already own the GPU
- Small team
- free software; the hardware for local inference is the cost
- Medium team
- free, but budget GPU capacity for the whole team
- Large team
- free, though at this size paid hosted inference usually beats buying GPUs
