Clean Attachments

Threat Extraction cleans an attachment and executes the configured workflow when these conditions are met:

The attachment is of a supported file type.
The attachment contains one of the supported active parts for removal.
The attachment is not detected as malicious (if malicious, the Anti-Malware workflow will take effect).

In addition, Threat Extraction excludes an attachment from cleaning when these conditions are met:

Other attachments in the same email are password-protected.
The workflow for password-protected attachments is configured as Require end-user to enter a password.

When an attachment is not cleaned, its original version is included in the email sent to the end user, and no restoration is required by the user.

Note:

For standard email security actions like removing potentially risky attachments. To help maintain the integrity of digitally signed messages, Avanan offers the ability to avoid security modifications for S/MIME-signed emails. See Support for S/MIME-Signed Emails.
