MetaClean for Zimbra
MetaClean for Zimbra is a Zimlet-based solution developed for Zimbra mail servers. It allows you to delete, add or modify metadata automatically in the documents of the attachments sent by email, providing security in this type of communications and protection against future attacks of Phishing, since it prevents the exfiltration of information through the metadata, which are commonly used in this type of cyber-attacks.
Implement some Data Loss Prevention (DLP) functionalities to prevent confidential and critical information from leaving the organization.
- File formats compatible with Metaclean
- Automatic metadata processing of email attachments regardless of the email client used (SmartPhone, web client, Thunderbird, Outlook, etc.).
- Does not require any software to be installed on client computers.
- Compatible with all versions of Microsoft Office, Open/Libre Office, PDF and more than 50 image, audio and video file extensions. Even if the files are compressed (ZIP, 7Z).
- Allows you to create whitelists by mail domains, the metadata of attachments whose recipients belong to these lists will not be modified.
- Centralised management of each of the established metadata policies: Allows you to delete metadata or apply templates including personalised metadata.
- Log/Audit files: All the activity performed is saved in a log file.
- Efficient use of server resources: the process of deleting, adding or modifying the metadata of the documents attached to the emails is executed only when the files are attached to the email, freeing resources at the end of the process.
- Protection against ZIP-BOMB attacks.
- Detection of signed PDF files: The metadata will be processed depending on the configuration, which avoids invalidating the signature accidentally.
