TLS is secure but only in part and with no assurance. It’s no longer acceptable in cybersecurity circles as an assured means of securing email. With TLS, if the certificate is out of date or invalid, it reverts to clear text. Additionally, the end user has no way of knowing how the store-and-forward has worked and whether it was secure or not from end to end. The only way to make certain is through using Pre Internet Encryption (PIE). Galaxkey uses PIE, thus the user is assured when they press the secure-and-send Galaxkey button that the data is enveloped in our secure tech, and is sent over any network securely – accessible only by the intended recipients.
