MetaClean for Zimbra is a Zimlet-based solution developed for Zimbra mail servers. It allows the automatic processing of the metadata of the attachments sent by email, providing security in this type of communication and protection against future Phishing attacks, as it prevents the exfiltration of information contained in the documents, which is often used to create this type of cyber-attacks.
It implements Data Loss Prevention (DLP) functionalities to prevent confidential and critical information from leaving the organisation.
Zimbra has proven to be a truly useful email platform in the work environment. Its functionalities allow an organisation's workers to send, receive, save and search the messages processed daily in a very efficient way. However, Zimbra itself does not contain a specific function for controlling the metadata included in documents shared as attachments.
That a lot of sensitive metadata capable of providing your company's confidential information travels from email inbox to email inbox and without any kind of control. Different types of information that could lead not only to serious financial losses but also to serious reputational damage. Without specific software for handling metadata, your Zimbra mail becomes an inexhaustible source of information leakage.
Aware of this problem, at Adarsus we have developed a component -Zimlet- for the management of metadata in Zimbra mail servers. A tool that gives organisations back control over their data flow and is compatible with the main office software formats (Microsoft Office, Open/Libre Office, PDF and RTF).

MetaClean Zimbra incorporates functionalities Data Loss Prevention, The metadata is a powerful tool to prevent files containing an organisation's confidential and critical information from leaving the organisation, either accidentally or intentionally. After all, metadata provides a lot of potentially dangerous information. Such as personal data of third parties.
