Making cybersecurity accessible to all of Switzerland — Dohzel by Hafnova.
Context
Dohzel — Hafnova's flagship product — already had a first prototype in users' hands.
Early signal was strong: there was real appetite for a Swiss-made cybersecurity app that didn't ask its users to become experts.
The next step was harder. Rebuild the product so it could scale to a public launch — accessible to a 60-year-old in Vaud and a 22-year-old in Zurich, available in three languages, and built on a foundation a small team could keep extending.
01
Cybersecurity without the jargon
We replaced every piece of technical terminology with everyday Swiss language and validated each screen with non-technical users across cantons. The threshold for shipping copy was simple: a non-expert friend should understand it the first time.
02
One-tap protection, opinionated by default
The most important security actions were reduced to a single tap, with strong defaults baked in. Advanced configuration stayed accessible for power users — but it never sat between the everyday user and being protected.
03
A design system the small team could keep extending
Given the engineering team size, every screen was built on a tight component library. The localized FR / DE / IT versions, future features, and v2 work all sit on the same foundation — no rework needed.
12 weeks. Measurable shift.

What I'd do differently
Working with a team this early means most of the value is invisible at launch — it's in the decisions you don't have to revisit later. We aimed every choice at the team's ability to keep shipping after I left.
