What it is

Kestrel OS in a paragraph

Kestrel OS is a Linux distribution and lab environment for learning offensive security the right way: a curated toolset, the Kestrel Control Center, ready-made virtual machines, and a structured path from the foundations to Active Directory, with lab safety rules built in so practice stays where it belongs. In development.

Planned for the first release

  • A curated offensive-security toolset
  • The Kestrel Control Center
  • Ready-made virtual machines for the lab
  • A structured path from the foundations to Active Directory
  • Lab safety rules built in

This page describes what we are building. There is nothing to download yet, and we do not take pre-orders. When Kestrel OS is ready it will be listed as available on the products page. Have a job in mind for it? Tell us through the feedback form.

The same five rules as everything we make

What Kestrel OS will and will not do

Offline where the job allowsConnected products state exactly what they send and why, and every connection is listed.
Your data stays yoursNo accounts unless the job needs one, no analytics, no crash reports, no selling. Where it must store data, it says exactly what and where.
Honest about state"Available" only when you can download or use it. Everything else is labelled, and plans change when we learn something.
Pay whatever you wantFree to use. If it helps you, tip what you think it is worth, once or whenever you like. No paywalls, no feature ever switched off.
Built for the machines people actually haveTested on ordinary hardware first: mid-range phones, small laptops, small servers. Requirements are stated.
