“At Tungsten, the natural next step for us to boost the security of our encrypted chat app was to introduce a hardware layer that protects our users’ private personas. […] As experts in mobile device security, Cotech helped us integrate their solution into our existing codebase to build a hardware key that protects users’ anonymous personas and their data on Tungsten.”
