Sophos UTM 9.1 Released

I am pleased to inform you that today, after months of research, development, (and public testing by you), we have released Sophos UTM 9.1. This major update to our UTM line introduces dozens of new features, offers vastly increased performance in throughput and reporting (to name a few), and all-told makes UTM an even more formidable solution. You will find an amazing new system for enforcing your Web Security settings on clients anywhere they are in the world using our UTM Endpoint offering, wireless repeating and bridging using a mesh network option for our Wireless AP50, and SSL VPN for iOS and Android mobiles. We could go on, but first I invite you to download and install the Up2Date so you can start using all of the new abilities and see what else awaits you in UTM 9.1! Read on for download information, release notes, and all the details… 

Below is the download links for the Up2Date from 9.006. Hardware and Software appliance ISO's for fresh installations of UTM will follow shortly. You will also find various specifics around this release. For a list of all the new features and functionality, you can download the official UTM 9.1 Release Notes. If you have a Sophos UTM Smart Installer, the new UTM 9.1 version will show up as a possible download using the provisioning software very soon (if it hasn't updated already).

Known issues note regarding Virtualization:
There is a small problem which leads to deadlocks during boot-up on some versions of the KVM virtualization if the KVM instance uses more than one CPU. The workaround is to only use this version in KVM instances with one CPU.
The ISO installer sometimes hangs on start-up when using Citrix XEN. The workaround is to install 9.006 and use the Up2Date to 9.100 to run this version. 


Up2Date Installation: Sophos Up2Date technology makes it easy to upgrade your Sophos UTM to the latest version. There are two ways to apply an already-downloaded Up2Date package to the system:

  1. Log on to WebAdmin, navigate to Management >> Up2Date >> Overview and use Update to latest version now to install the Firmware Up2Date. Click on the “Watch Up2Date Progress in new window” and an extra browser window will show the progress of the Up2Date installation. (The System administrator will receive a notification email once the Up2Date process has finished.)

  2. Download the Up2Date package from our HTTP or FTP Server and install it under Management >> Up2Date >> Advanced:
