With the explosive growth in recent years first of broadband internet connections, then more recently with 3G mobile broadband, there has been a growing expectation among users and organisations that data should be available everywhere.

Users want access to files and emails from home, hotel rooms, wireless hot-spots, and even on the move. Furthermore businesses increasingly want to support home working and mobile computing.

Fortunately to support these demands, manufacturers such as SonicWALL have created modestly priced Firewall and Unified Threat Management (UTM) appliances. These protect business from Internet borne threats, manage what traffic can and cannot pass over an internet connection, may scan for viruses, may manage web and email content, and support site-to-site and site to mobile user Virtual Private network (VPN) connections.
