Try it FREE 6 Most Secure Email Providers In the next part of this article, we talk about 6 most secure email providers and the services they offer.ĭesigned and built with your privacy and security in mind. If you're wondering how to send a secure email using OpenPGP, we recommend you read this excellent tutorial from The Privacy Guide.īut you can also skip the reading because most free secure email providers make end-to-end encryption incredibly easy by hiding all the complicated technical stuff behind an intuitive user interface. The most popular data encryption standard that allows anyone to send and receive end-to-end encrypted email messages is OpenPGP. In practice, end-to-end encryption allows you to encrypt an email at your end and send it to someone using a secure email service without any possibility of the email being decrypted by the secure email service. However, most secure email providers go a step further and offer full end-to-end encryption, meaning the data is encrypted and decrypted only at the endpoints. Without TLS, the communication between email servers is transmitted as plain text, and anyone with relatively rudimentary knowledge of computer networks can intercept it and read it. Over the years, many technical workarounds to ensure better privacy of email communication have been implemented by email providers, and several secure email services have emerged, offering high levels of privacy and security.Īll best email service providers today have implemented transport level encryption using TLS, which is a cryptographic protocol that provides communications security over a computer network. The internet email message format, as it's defined by RFC 5322, specifies a syntax for text messages that are sent between computer users, but it doesn't deal with encryption or any other means of preventing unauthorized access to personal information exchanged via email. Today, our security requirements are radically different, yet email hasn't changed all that much. Back when email entered limited use in the 1960s and 1970s, security wasn't anyone's top priority.
