Under this scenario, email is encrypted on the sender’s device using a public encryption key of the recipient before being transferred to a ProtonMail server and the recipient. (Even ProtonMail can’t do this.)Įnd-to-end encryption, by contrast, occurs when both the sender and recipient use ProtonMail. In other words, the user is the only one who can decrypt the message. Here, the mail is encrypted using a ProtonMail public encryption key explicitly tied to that user. In this case, let’s say the email came through Gmail. The first, zero-access encryption, occurs when a non-ProtonMail user sends an email to someone who uses ProtonMail. With trust in big brand technology companies steadily eroding, companies like ProtonMail are hoping to pick up the slack and offer something different. ProtonMail offers two types of email encryption, depending on your situation. A few years earlier, a Yahoo breach affected 3 billion users! A 2018 security breach at Google was so bad it forced the technology giant to shut down its social network, Google Plus. In the past two years alone, personal data collected by Facebook from nearly 592 million users were exposed through various breaches. The largest data breaches in recent years have occurred at some of the biggest names in Silicon Valley. Unfortunately, data breaches have become commonplace, affecting billions (yes, billions) of users. Despite this, the expectation has always been that companies are trying their best to protect our data from wandering eyes. Most email services are provided for free. Instead, the emails are stored across server farms along with those of millions of other users.
As part of the process, these emails and their attachments are kept somewhere in a cloud, which is neither an actual cloud nor located in the sky. Through computers or mobile devices, end-users can send emails to others all around the world. Though features might differ, each operates in similar ways.
What is ProtonMail?īefore discussing ProtonMail, it’s important to understand email systems, in general.Ĭloud-based email services have been around for decades. Once only for CERN scientists, the Swiss-based email service is now used by millions of people across 150 countries. It’s time to consider ProtonMail, which promises both zero-access and end-to-end encryption to protect your data.
