Virtual Private Networks
Today’s workforce is increasingly mobile. Telecommuting is on the rise, as is the number of people who work on the road or in locations other than corporate headquarters. Unfortunately, with the rising number of mobile employees and other remote users requiring access to corporate networks, organisations are facing serious new costs and information security challenges. Since the Internet is generally accessible with a local phone call from nearly anywhere in the world, the remote user can establish a remote access connection to corporate network resources through the Internet, dramatically reducing remote access costs. 

Early indications show that an average of  £1,000 in savings per user/per year can be realized through deploying a Virtual Private Network (VPN), due to the reduced hardware and support requirements needed.
