sure. As the Products/Free Tools page says it is Upgradeable for support and centralized management but otherwise fully functional and free. Please note that there is no guaranty that it will stay free forever and very likely there won't be any new features. Just curious - this would be the only machine (whether server or workstation) where you'd have Sophos installed?
I'm not Sophos and I'm not a lawyer. But I assume MarkToshack would have objected to my simple statement. Please note that the referred thread is almost four years old, it was around the time the free version came out. IIRC there have been changes since then, not only w.r.t. the legal side but also downloading/updating. You needed the MySophos account credentials whereas now it automatically fetches a set of credentials when you indicate you want to install the free version. Initially it was an equivalent of the free version for Macs targeted at desktop users. Seems that someone thought better of it. Legal considerations aside - the free version is IMO anyway not suitable for use as component of services like email provided to customers as it lacks the interface required for reasonable performance and usability.
