Free Sophos UTM Essential Network Firewall for Windows 10/8

There are plenty of free firewalls available for home networks. With Windows 10/8.1/7, you do not need a separate firewall, as the built-in Windows firewall is good. For extra protection, you can turn on the firewall in your router/modem. But if you think you need even better firewall to protect your data, Sophos is a new release you may want to consider. The article checks out the features of Sophos Free Essential Network Firewall.

Sophos UTM Free Essential Network Firewall

One of the editions is the ready to use VMware Virtual Appliance and the second edition is a software application.

You will need a dedicated computer to use Sophos firewall application. By dedicated, I mean that the computer will have its Windows installation files rewritten. That won’t spoil your network configuration and will use Sophos as a virtual hardware firewall. This type of configuration ensures maximum protection against unauthorized attempts to get into your network.

System Requirements for Sophos Free Firewall Application Edition

  • 1.5+ GHz processor (dual core+ recommended)
  • 1 GB RAM (2GB strongly recommended)
  • 60 GB hard disk
  • Bootable CD-ROM
  • Two or more network cards

The last requirement of having two network cards implies it will be used as a client-server network models.

System Requirements for Using Sophos VMware Edition

  • 1 GB RAM
  • 40 GB IDE or SCSI hard disk drive
  • Two or more network cards

This edition is pre-configured to blend into different types of virtual environments.

Installation of Sophos Firewall

Unlike other software, you won’t get the download link directly on Sophos website. When you click the download button, you are asked for your name and email ID. The company then sends you a detailed email on how to access, download and install the software. All links are available with the email, including the link for help files.

I feel they use this method to ease the installation process, by providing the detailed installation information for both application and VMware edition of Sophos – any to get your email ID!

In both cases, after installation, you will have to upload a license file before Sophos starts protecting your computer network.

In the case of app version, you will have to create a bootable CD using the link to the image file they give you in the email. You have to boot with that CD to launch a walkthrough that will guide your installation. This extra step, I suppose, is to further ensure safety during installation. In other words, it boots via CD to avoid possible malware tampering the installation.

Sophos Deployment Scenario

Essential Features of Sophos Free Network Firewall

The top two features of Sophos are explained below:

  1. Location based Denial: The firewall provides you an option to create your own rules. While configuring Sophos, you can configure it to reject packets originating from a certain country or a list of countries.
  2. Encrypted Access To Your Office: Wherever you are, if there is an internet connection, you can use it to connect securely to your Office’s private network. This is actually a VPN providing encryption so that your data is not accessible to others at the place you are – for example, airport or a coffee house.

Among other features are network monitoring. This not only monitors how the different devices are functioning but also provides you with data in the form of charts for better understanding. From these charts, you can figure out if any app is leaking or using more resources than required.

On a negative note, Sophos firewall cannot be used on a P2P networks. I do not think many of us still use P2P but, for those who share a common connection without having to keep a central computer running all the time, Sophos is not the answer. On the other hand, as shown in the image above, the deployment can be done as a client-server model. The computer containing Sophos is connected to the external world while all other devices are connected to that computer.
