We believe security should be available to everyone. We offer ProtonKey for a low price without sacrificing security.
Our story begins where the web was born - at CERN, where our founding team of scientists met. Like ProtonMail, ProtonKey is a community supported project with a simple goal: to build a safer Internet that also protects civil liberties.
