MetaClean for Gmail removes, adds or modifies metadata in email attachments, thus preventing the leakage of confidential information that occurs on an ongoing basis in this type of communication and avoiding potential economic and reputational damage from malicious use of metadata.
To avoid exfiltration of information through metadata, this information is often used to generate phishing attacks.
All documents contain metadata, which is embedded in the file and often contains sensitive or confidential information such as: author, change history of the document, login user, contact email, how much time was spent editing the document, path to the directory where the document was stored, version of the software used to create the document, etc.
The removal of potentially harmful metadata is a fundamental task within any organisation to avoid information leaks related to the sending of files via e-mail.
