What our customers say about us
Rayan Dawud
"With Big Tech increasingly complicit in actions that compromise fundamental privacy and human rights, I made the switch from Google to Proton for both email and file storage about a month ago. And honestly? I’m never going back."
Kate Hammer
"I use local backup only for documents relating to my client work outside my practice management software, and have a drive on Proton for cloud access on the rare occasions I need it."
