Pathway uses TLS encryption when sending emails.
TLS is a protocol that encrypts email data as it travels from the sender’s email server to the recipient’s. TLS uses asymmetric and symmetric cryptography to encrypt email data. That means it generates and exchanges a session key through asymmetric cryptography, then the sender and recipient use this key to encrypt and decrypt the message.
This prevents cybercriminals from reading the contents of an email while it’s in transit, known as a man-in-the-middle attack.
