Data Control

The Data control policy allows you to create rules for monitoring or restricting messages and attachments based on content, filename, or file type.

Data control allows you to reduce accidental data loss from workstations by monitoring and restricting the transfer of files containing sensitive data.

Accidental data loss is commonly caused by employees mishandling sensitive data. For example, a user sends a file containing sensitive data home via web-based email.

The Data Control page allows you to configure both inbound and outbound rules. By default, there are default rules on the Outbound tab that are based on SophosLabs Content Control Lists (CCLs). The terms "inbound" and "outbound" refer to messages received by the Sophos Email Appliance, and messages delivered through the appliance.

Use the Configuration > Policy > Data Control page to configure CCLs and other data control options.
