Web DLP — Configure DLP Scanning As Part of Your Web Policy

You can configure several parameters and functions of DLP scanning as part of your web policy. This includes configuring a rule that allows files to bypass DLP scanning, which would otherwise be part of the filtering process that is performed to ensure web security.

This bypass is configured based on media types. In the following, it is explained how to configure this bypass using a bypass list, as one of the steps for configuring a default web policy rule set.

The bypass list does not work for some media types. You need to use a workaround here to exclude, for example, multipart media from DLP scanning. For more information, see Configuring Media Types to Bypass DLP Scanning.

For more information about how to configure what is related in your web policy to DLP scanning, see Manage Web DLP from Web Policy

  2. On the policy tree, expand Data Protection (DLP) and select Web DLP.
