While ProtonMail remains a leader in the secure email space, it has also attracted some controversy lately, which we’ll examine in detail below. Guest author Sven Taylor is the editor of Restore Privacy, a blog dedicated to inform about best online privacy practices, secure your electronic devices, unblock restricted content and defeat censorship. It utilizes PGP encryption standards, is based in Switzerland, and has a solid reputation in the privacy community. If you want to protect your email from prying eyes, but don’t need the kind of protection that keeps spies and whistleblowers alive, ProtonMail could be the secure email service for you. ▪ Price: $4.00/mo ▪ Free tier: Up to 500 MB The service offers RSA 2048-bit and AES 256-bit protocols, using RSA 2048-bit for emails between users and AES 256-bit for communications between users and non-users.▪ Based in: Switzerland ▪ Storage: 5 GB to 20 GB Tutanota also uses perfect forward secrecy, a style of encryption that prevents cybercriminals from accessing future sessions after hacking a previous one.ĭespite not encrypting email subject lines, ProtonMail provides almost the same level of end-to-end encryption. Though Tutanota doesn't support OpenPGP, it uses the same algorithm as Pretty Good Privacy (PGP), a program used to encrypt and decrypt emails. It encrypts your email subject lines, body, calendar, and address book, keeping your contacts and meetings secure. Tutanota encrypts more sections of your email and inbox than ProtonMail. Not even the company can decrypt your messages. Tutanota combines AES 128-bit and RSA 2048-bit protocols to provide end-to-end encryption.


Both email services use end-to-end encryption to secure the contents of your inbox, meaning only you can read them.
