Difference between XG Firewall and UTM9

Release Notes! Finally I've got a working link!

docs.sophos.com/.../Sophos XG Firewall Release Notes.pdf

It does have a small comparison, and links to the documents that Sandy points out.

Hello, I'd be happy to try and address this... although I encourage everyone to keep current with the Sophos Blog as there is a ton of information there on what's new and different and there will be more coverage of what's new in the coming days.

The short answer is that Sophos UTM 9 is our leading and award-winning Unified Threat Management (UTM) platform. Sophos UTM has a long and successful history that extends back several years.  Of course, it's not going anywhere.

Sophos XG Firewall, is our new firewall platform, that combines some of the great technology from UTM 9 with a variety of new technology including support for the new Sophos Security Heartbeat, a new user interface, improved user-based policies and reporting, and much more.  It is a very innovative and capable UTM and Next-Gen Firewall.

If you want more detail, there is a good overview of the innovations in XG Firewall on the Blog (that are not in UTM 9).

There are also some features in UTM 9 that haven't yet made it into XG Firewall.  Those are highlighted in the UTM 9 FAQ Blog Article. 

That should hopefully get everyone started... if there are still questions after reviewing that stuff, please post back here, and I'll do my best to answer.
