GFI MailEssentials features advanced malware protection that enables IT admins to secure their email infrastructure from the new breed of malware that creates different variants of itself to avoid detection.

This is done via the new and improved Kaspersky AV engine, that can connect to a cloud service whenever it finds unknown executable attachments. These attachments are thoroughly scanned through the intelligent Kaspersky cloud engine to determine if the attachment is malicious or not.
