Sophos Enterprise Security and Control provides complete protection for an organization's desktops, laptops, mobile devices, file servers, email gateway and groupware infrastructure, and all web browsing needs. Sophos's unified engine defends every point, controlling not just malicious software and activity but also preventing data leakage and the misuse of legitimate software applications, including VoIP, IM, P2P, internet browsers, media players and games. A single per-user licence allows all Windows, Mac and Linux endpoints to be protected, enables software or appliance protection at the email and web gateway and the protection of Microsoft Exchange and Lotus Notes groupware servers. There is also an option for larger organisations to control network access.
