We build the layer everything else trusts.
Z‑index Zero is a security company with one stubborn idea. Trust should sit at the very bottom of a system, where it can hold everything else up. We want everyone to have that strong base, from one person guarding their files to a country guarding its missions.
The name is a promise.
In web design, z-index: 0 is the bottom layer. Everything else on the page is stacked on top of it. Move it, and everything above it moves too.
Most security is built the other way around. It gets added on top of a system after the system is already running, and then everyone hopes nothing underneath breaks. We thought that was backwards. So we started at the bottom and built up. Every layer above gets that base of trust automatically.
That's the whole company in two words: layer zero.
// our missionTo make the base layer of trust something anyone can stand on. We want strong security to be for everyone, whatever their budget.
Rules we build by
Security belongs at the bottom
Protection should be built in from the start. We build at the bottom layer, so everything on top of it starts out safe.
Trust is earned, then proven
We don't ask you to just take our word for it. We design our promises so you can check them yourself.
Built for everyone
The same base of trust can grow from one person's files to a whole country's systems. Strong security shouldn't cost a fortune.
Privacy comes first
We want your data kept private, even from us. Our planned Personal vault is designed so we can't read your files. That goal shapes every choice we make.
Plain words
Security should make sense to everyone. If you need a word list to use a feature, we haven't finished designing it.
Aim for the toughest standard
Meeting the hardest rules makes things safer for everyone. What we learn building for defense will make personal vaults stronger too.
One foundation, three layers
