With dDesk, users can access their personal work environment from any location. The virtual PC workstation is housed on an external server in a highly secure Deutsche Telekom data center, where data is also stored and maintenance carried out. The user requires a computer with an operation system, Internet access and a USB port. The dDesk Key, which looks like a flash drive, is also required for authentication. With dDesk, T-City is targeting small companies and private users that wish to reduce their PC administration tasks and avoid large investment costs.
