File hash list

You can create a list with the hashes of files that you don’t want scanned by data loss prevention (DLP). In a file hash list, make sure you enter the hashes in SHA-256 format. Like any custom list, you can assign these lists to policies. File hash lists are assigned the bypass policy action.

You can use this feature to allow users to upload files that contain sensitive information and would otherwise be detected by DLP. You can enter file hashes that you have or if this file was previously downloaded or scanned by ETP Proxy, file hashes are provided in the Proxy Activity report. You can copy the hash values from the report and use them in this configuration. If you want to generate a hash value for a file, see Generate a hash value.

When DLP is set up and the file hash list is assigned to a policy, ETP checks the file hash list to determine whether the file should be bypassed. If a user uploads a file that is in this list, the upload is allowed.
