US Patent 11943193 Misdirected email data loss prevention

Aspects of the disclosure relate to data loss prevention. A computing platform may detect input of a first target recipient domain into a first email message. The computing platform may identify, in real time and prior to sending the first email message, that the first target recipient domain is an unintended recipient domain instead of an intended recipient domain. The computing platform may identify, in real time and prior to sending the first email message, that the first email message violates one or more data loss prevention rules. Based on identifying the violation, the computing platform may send a notification that the first target recipient domain is flagged as an unintended recipient domain and one or more commands directing a user device of the message sender to display the notification.
