Wij bouwen aan een internet dat privacy beschermt, beginnend met e-mail.

Wij zijn wetenschappers, ingenieurs en ontwikkelaars die samenwerken onder een gedeelde visie om online burgerrechten te beschermen. Daarom hebben we ProtonMail ontwikkeld, een gebruiksvriendelijke en beveiligde e-mailservice met ingebouwde end-to-end-versleuteling en de meest moderne beveiligingsfuncties. Ons doel is om een internet te bouwen dat privacy respecteert en goed beschermd is tegen cyberaanvallen.

We zijn toegewijd aan het ontwikkelen en verspreiden van de benodigde hulpmiddelen om uw gegevens online te beschermen. Ons team combineert diepgaande wiskundige en technische kennis van de beste onderzoeksinstellingen ter wereld met expertise in het bouwen van gebruikersinterfaces die gemakkelijk te gebruiken zijn. Samen bouwen wij aan de versleutelde communicatietechnologieën van de toekomst.
