Settings for Detecting Password-protected Attachments (HENNGE Email DLP)

Overview of Functions 

HENNGE Email DLP can detect whether attachments have passwords set and can take actions (send, hold, delete) accordingly.
Specifically, there are two detection methods:
・All attachments are password-protected.
・At least one attachment is password-protected.
For example, with this setting, you can:
- "Send if all attachments are password-protected."
- "Delete or notify if only one attachment is password-protected (preventing double encryption)."
This allows for more flexible configurations.


・Compatible with general business documents. Common file formats include:
MS-Office Word / Excel / PowerPoint, PDF, ZIP, 7z, RAR.
・For PDF, ZIP, 7z, and RAR files, the file format compatibility may be affected by the application or environment that created the file, and there may be cases where it is not identified as "password-protected."
・If a ZIP file with a password and a JPEG file are attached, it will not match "all are password-protected."
