The Zscaler Outbound Email Policy lets you use the same Zscaler Data Loss Prevention (DLP) policy tools that you use across other channels to protect your organization from data loss in outbound emails sent to external domains. You can use Zscaler custom and predefined DLP engines to detect sensitive data, allow or block user activities, or to add custom headers to emails that trigger an outbound email policy rule. If you don't use Zscaler DLP engines, the service functions instead as a filter, only flagging content based on specific criteria. To learn more, see Step-by-Step Configuration Guide for Zscaler Outbound Email DLP.
