Astaro was probably the best edge UTM out there for quite some time. I used them from the first v4 all the way up until now. Astaro was then purchased by Sophos and it became a morass of corporate interference, no service to their smaller partners, a series of badly executed acquisitions and unreliable products as a result. After months of pleading for Sophos to provide me with a license for their new Cyberoam based SFOS as laid out in their not for resale document I still have not received the license. I have grown weary of being ignored. I am a small one person shop. To my clients I am a valuable member of their team so they can do business. To Sophos I am nothing to be concerned with. This is unfortunate as I have been one of the biggest advocates of their (formerly Astaro) UTM for many years. That ends as of today. I am in the process of bringing two vendors in to replace Sophos. The first is Meraki. I am not a fan of their business model but I have clients asking me for it. The other is Sonicwall. The interface is byzantine but I have NEVER had to wait for days, weeks, or even months for a response to any inquiry no matter how mundane. I have built my business on service and I hold my vendors to the same standard. If you are not providing service to me and by extension my clients, out you go.
I am now singing up to partner with three of the premier network security vendors in the world market:
Cisco
Meraki(Cisco)
Dell Sonicwall
