The provided source explains how to configure Transport Layer Security (TLS) for email security within a Google Workspace environment, focusing on the Secure transport (TLS) compliance setting. TLS is introduced as a protocol that encrypts email messages to prevent unauthorized access during transit, with Gmail attempting to use it by default if both the sender and recipient servers support it. The document outlines the steps an administrator must follow in the Google Admin console to enforce TLS for specified domains or addresses, including creating or selecting address lists and setting options such as requiring a CA-signed certificate and validating the hostname.
