This is a Beta release of Sophos UTM and is not recommended in ANY way for production environments! Not only is it not a final representation of the product we plan to offer for the general masses, but it will probably break things in your network at scheduled, random, or just impulsively evil intervals. If by deploying this early into an environment which cannot tolerate inconsistencies, downtime, or failures you incur the wrath of your superiors (or worse, your users), then you are alone in that fight and have no champions to summon in your defense.
However if you, (like so many of us) need to see new things at the earliest opportunity and want to familiarize yourself with what we will offer to the masses when it is fully-baked, then we invite you to steel your resolve and enjoy this beta release. For your efforts, you will have the chance to give feedback and truly affect and shape this release. In return, you agree to not gather outside our gates with pitchforks and torches if we throw you the odd hiccup as we alter and "improve" things.
