Emails are a very difficult means of communication to provide adequate protection. The problem with protecting your email is that it must be encrypted from end to end to prevent it from being intercepted when traveling on intermediate networks, and the recipient must have the same encryption system. Which email service is most secure?
The 5 most secure email services
ProtonMail is a free provider of encrypted, open source email messages based in Switzerland. The most important feature when talking about any encrypted email service is whether other people can intercept your messages and the answer is unambiguous when it comes to ProtonMail because it offers end-to-end encryption. ProtonMail is so secure that it cannot recover emails if you forget your password. Decryption takes place after logging in, so the service cannot decrypt an email without a password or recovery account in a file.
Countermail is about user safety. Although its interface looks quite outdated, its system is regularly updated and email security is second to none. Like ProtonMail, it also offers comprehensive encryption between sender and recipient and uses OpenPGP to protect e-mail messages and e-mail accounts. Because it uses diskless data servers, no one will be able to read or write anything you send through those servers.
Hushmail is another encrypted email service that has been around since 1999. Ensures the security and blocking of email messages using the latest encryption methods. Even Hushmail cannot read your messages; only the person with your password can do it. With this service, you can send encrypted messages to Hushmail users as well as to users who have accounts in Gmail, Outlook Mail or other similar email clients.
Mailfence is an encrypted email service based on the OpenPGP standard that offers comprehensive encryption and digital signing. It was launched in November 2013 by the ContactOffice Group, which since 1999 manages the online collaboration package for professionals, universities and other organizations. Unlike other private and secure messaging services found on the Internet, Mailfence does not block users from their own “digital island”. It leaves its users complete freedom of secure communication with anyone, be it with other Mailfence users or any other email service.
Tutanota is similar to ProtonMail in design and level of security. All Tutanota emails are encrypted from sender to recipient and decrypted on the device. The private encryption key is not available to anyone else. This email account is all you need to exchange secure emails with other Tutanota users. For encrypted email outside the system, specify the password that the recipient should use when viewing the message in the browser.
