Build the tool you would want to run.
We build Zero Door, publish what we find when we break things, and run engagements in regulated and air-gapped estates. Small team, written decisions, evidence over claims.
Send a general application- Product engineering
A Rust agent on the host, a service backend in Go, and a web dashboard people use every day. Performance, correctness, and evidence that holds up in an audit.
- Security research
Red team operations, reverse engineering and integrity research. What we find goes out under our own name, not into a brochure.
- Services
Penetration testing, red team engagements, training and consulting, run by the same people who build the product.
What you can expect from us.
Evidence over claims. Decisions come from measurements, and the reasoning is written down where the next person can read it.
What we find, we publish. Research goes out under our own name, including the parts that were inconvenient.
The estates we build for are regulated and air-gapped, so the bar for reliability is high.

- Where you are and how you prefer to work.
Recruitment fraud
We write only from @zeronesecurity.com addresses. We never ask candidates for payment, for equipment purchases, or for financial details. If a message claiming to be from Zerone does any of that, it is not from us.
No opening that fits? Write anyway.
Tell us what you have built or broken. We read every application and reply within one working day.
