When using Glasswall Meteor, you’re able to set your own preferences or
‘policies’ for each of the supported file formats via the *Policy settings*
section.![13_policysettings](/.attachments/13_policysettings.png)

Policy settings are used to specify whether risky content is sanitized (removed from
the file), allowed (left in the file) or disallowed (the file is not rebuilt).

* From the side navigation bar, select **Policy settings**. The numerous settings for each file format are displayed.
* Modify as required and click **Save**.

As a default, we recommend setting all content management settings to
*Sanitize*. This will provide the best balance between security and usability.
Allowing certain types of risky content presents a risk to you if an attacker
has placed malware within a file. You can choose to disallow files with certain
criteria, but this will block CDR from being performed on those files. For
these files, the rebuild process status will be marked as *Can't be cleaned*.
