Email Security.Cloud Data Protection rule is not working for a password protected compressed file

Products

• Email Security.cloud

Issue/Introduction

The data protection policy for messages with password protected attachments is not triggered on a .7z archive.

Environment

Email Security.Cloud

Resolution

There is an expected difference in the processing between encrypted and non-encrypted .7z attachments.

The product will work for password protected non-encrypted .7z attachments.
For the password protected encrypted .7z attachments, the file will not be picked up by the engine and this is expected due to technological limitations.
