The Sophos UTM products helped us manage and a global network of more than 20 sites.
Their ability to firewall, filter and monitor network traffic and provide VPN connectivity really helped us day to day with such a complex network.
We chose the product initially because the user interface was simple to understand and made sense without requiring a long training course for an experienced network engineer to utilise.
Central Management is made easy with the Sophos UTM Manager which allows you to set configurations, see patch status and pull reports from all your estate.
While the product was originally with Astaro the low end (1xx) units had serious reliability issues and support was extremely challenging to engage with. However, once Sophos took over their world class technical support teams soon brought responsiveness up to the level I would expect from a premium product. And the newer hardware is much better quality.
The ability to have either software, hardware or virtual appliances allows excellent freedom of choice.
High Availability is easy to configure and works really well, with options to have either active \ active or active \ passive depending on your needs and budget.
The fact you can use the full product for Free at home is a wonderful idea for engineers to become more familiar with the product and keep their skills up to date.
