Providing secure end-to-end notifications from a notification source to a notification sink despite the notification mechanism including one or more message transit points between the notification source and the notification sink. Initially, security information (e.g., the master security, the cryptographic algorithm, and the like) is negotiated out-of-band from the one or more message transit points so that the message transit points are not apprised of the security information. When a designated event occurs, the notification source generates a push message that includes the notification encrypted using the pre-negotiated security information. When the notification sink receives the push message, the notification sink decrypts the notification using the pre-negotiated security information, as well as supplemental information provided in the push message. Thus, the message transit points only have access to the encrypted form of the notification.
