Sophos Home Premium for Linux
Sophos Home Premium is only available for Windows, why not for Linux and Macs. There are a large amount of Linux users that would value a Premium license for Linux home users. Not sure how secure is the free version of Sophos Linux AV. I'm sure users of Home Premium would valus te ability to see their Linux devices in the Sophs Home portal.
Linux users represent an extraordinarily low percentage (>2%) of the home user market. I'm sure that has something to do with the lack of movement in that department.
