Abstract

The present disclosure provides new and innovative systems and methods for filtering encrypted messages. In an example, a computer-implemented method includes obtaining a message, determining sender profiling features of the message, determining enterprise graph features of the message, determining header features of the message, determining a message flag based on the sender profiling features, the enterprise graph features, and the header features, and processing the message based on the message flag.
