XG Firewall and XG UTM and how does it compare to UTM9?

Firewall and UTM are different products. XG UTM is UTM9. Currently there is a gap in feature sets and both the GUIs and basic concepts of administration are quite different. You're question is best served by giving you a link to the XG Firewall (SFOS) trial, which can be installed in a VM, so you can play with it and make a comparison. www.sophos.com/.../next-gen-firewall.aspx.  Some people like the new Firewall, other UTM users would rather hit themselves in the head with a hammer than to have to use it.  A very subjective thing, so take the time to make up your own mind.  The Firewall forums can be found at http://community.sophos.com/products/xg-firewall/f/46, if you have questions while using the trial.

If you are well versed in the intricacies of the UTM9 and/or SG then basically forget everything you know when you start working with the XG, the interface is completely different. I have never used Cyberoam so I can't say if it is similar to that or not. It is definitely a Windows 7 vs 8 type of foreign feeling when you go from SG to XG. Once you get used to how the XG works it isn't that bad, almost easier in some ways. At first I had trouble figuring out how SPX worked but then I found out I was overthinking it, coming from a UTM9 perspective it is much simpler now, almost transparent. On the SG you had to do a lot of setup and change settings in the mail client of every person that used SPX, not so with the XG. Since the XG can scan SMTP and SSMTP it looks at the header for the SPX signature and if present just encrypts the message. One thing you do have to make sure of is that you have a trusted certificate on the UTM and install that certificate in the trusted root store of each PC, otherwise they will get annoyed with popups every time Outlook tries to access the server. Once your workstations trust the UTM all goes smoothly. So far I'm liking what I see with the XG, haven't been using it for very long but it installed easily and worked well without too much tweaking. As the song from the 80's goes, "Things can only get better".
