Information from the Sophos Site:

Sophos is a world leader in IT security and control. We offer complete protection and control to business, education and government organizations – defending against known and unknown malware, spyware, intrusions, unwanted applications, spam, and policy abuse, and providing comprehensive network access control (NAC).

Our reliably engineered, easy-to-operate products protect over 100 million users in more than 150 countries. Our vision, commitment to research and development, and rigorous attention to quality have enabled us to maintain strong year-on-year growth and the highest levels of customer satisfaction in the industry.

Security and control

With 20 years’ experience and consolidated anti-malware, antispam, and policy enforcement expertise, we provide proactive, effective protection against security threats and unauthorized network access, while giving system administrators the security and control they need. Matched by business-focused, 24/7 technical support, we respond rapidly to both known and unknown threats, no matter how complex they are.

As with most Internet Security providers today, one can download trial versions of the software that is on offer which will remain fully functional for a period of 30 days. After this time, you will have to acquire a license to receive regular updates, which is no luxury, for cyber criminals do not stop their relentless attacks either.
