Company

The company behind Zero Door.

Zerone is a product company. We build Zero Door, we publish what we find when we break things, and we run every engagement with the same rule: evidence over claims.

The story

Why an integrity company.

  1. 01

    The problem

    Regulated organisations must prove, every day, that nothing on their servers changed without permission. The tools they had either drowned them in alerts or asked them to trust a dashboard.

  2. 02

    Our answer

    We started from the other end: read every file by content, decide what is legitimate, and keep evidence that stands on its own. That became Zero Door.

  3. 03

    The loop

    The research side never stopped. Red team work, reverse engineering and field notes feed the product, and the product feeds the research.

Who we are

What we do not do

  • Zero Door does not block, kill a process or quarantine a file. It detects, explains and evidences; the response stays with your team.

  • We do not claim certificates we do not hold. Zero Door maps to frameworks; a certification goes on the trust page when we obtain one.

  • We do not put third-party trackers on this site.

The Zerone logo is a glyph, the word zerone and two lockups that join them, horizontal and stacked. Use it in ink on light surfaces and in paper on ink. Do not recolour, rotate or add effects. The product name is written as two words: Zero Door.

The full logo system, with construction, clear space and minimum sizes, is on the logo page of the design language.
