Its idea: micro-virtualisation which puts every single task into its own virtual machine. The idea comes from the creators of the Xen hypervisor and relies on the fact that VMs do not interact with each other. For every browser tab or document, the user effectively unwraps a new PC which is thrown away after use. The firm has some customers for its still-somewhat-pricey idea (which relies on Intel's hardware support for virtualisation and is only available for Windows 7 right now). It also has to make sure it convinces on issues such as the transfer of files between possibly infected VMs."
