MetaClean O365 removes metadata (hidden data and personal information) in email attachments preventing the leakage of confidential information that occurs continuously in this type of communication and avoiding possible economic and reputational damages derived from the malicious use of metadata.

*** This AddIn must be deployed via Microsoft 365 admin center and it will be available to selected users or groups.

Why should you use MetaClean O365?

- Data Breach Prevention: Every document contains metadata. For example, metadata is embedded in the file and is different to the information that is typed on the page – such as Author, track changes or comments. It can tell the reader who created the document, how long was spent editing it, and where the document is saved. Cleaning a document of metadata means that the recipient will only be sent what would be printed. Removing potentially harmful forms of metadata from the attached files is a risk area that should be considered when investigating ways to prevent email-related data leaks.

- Phishing Attack Prevention: MetaClean prevents the exfiltration of information through metadata which is commonly used to generate phishing attacks.

- Ease of use and there is no user registration required: Just install and enjoy it!
