Sophos UTM (formerly Astaro Security Linux) is a commercial operating system designed from the ground up to be deployed as a firewall, gateway, anti-virus solution, intrusion protection system (IDS), VPN (Virtual Private Network), spam filtering, spyware protection and content filtering solution on small and medium-sized networks.
Available as a dual-arch, installable-only CD image
This product is available for download as a 30-day full featured trial, packaged as an installable-only CD image of approximately 650MB in size, suitable for both 32-bit (i386) and 64-bit (x86_64) hardware platforms.
The boot menu is very minimal, instructing users that the installation will completely erase all data on the target drive, including the currently installed operating system and all applications.
To start the installation, just press the Enter key when you see the boot prompt, which will appear immediately after you have booted the CD/USB media from the BIOS of the PC.
To view the recommended hardware requirements and possible boot options, do not hesitate to press the F1 key on your keyboard. Pressing the F3 key will display a troubleshooting screen.
The distro is quite easy to install, despite the fact that it features a text-mode installer
The distro is quite easy to install, despite the fact that it features a text-mode installer that requires you to select a keyboard layout, timezone, set the date and time, configure the network interfaces and partition the disk. To access its web-based interface and configure the system, open a web browser from another computer on the same network and point it to the IP address posted at the end of the installation.
If you own a small or medium-sized business and you want a strong, secure and commercially supported server-oriented operating system to block unwanted spam, filter web content, protect your employees from spyware and viruses, as well as to deploy a capable Virtual Private Network (VPN) gateway or Intrusion Protection System (IDS), then Sophos UTM is for you.
