Autonomous Offensive Security

Metnir is an offensive security lab. We build autonomous systems that find and exploit vulnerabilities in real-world software, and work with the teams behind it to fix them.

Our researchers have reported vulnerabilities to

  • LEGO
  • Cloudflare
  • F5 NGINX
  • QEMU
  • Molio

Built for Engineering Teams

The first attack on your product should be ours.

  • Before a launch

    Have the release attacked while it is still yours to change.

  • After a rewrite

    A new service or permission model moves the edges of your system. Test where they moved.

  • Before the security questionnaire

    Walk into your customer’s review with a recent assessment in hand.

  • After an incident

    Find out how far the reported issue reaches, and what else sits next to it.

What We Assess

  1. Applications

    Sign in as a customer. Leave as an admin.

    Agents use your web application and its APIs the way real users do, then go looking for everything those users were never meant to reach.

  2. Source

    Read every line. Then run it.

    Where you share source, agents read it alongside the running system and try what they find in the code against the real thing.

  3. Native

    One byte past the end of the buffer.

    Agents work through native and low-level code, looking for the memory errors that end in code execution.

  4. Continuous

    Then again on the next release.

    Software changes every week. After a first assessment, Metnir can follow your releases and test what is new.
