VPN's (Virtual Private Network) provide a secure connection from one remote location to another for remote PC access capabilities.  Door2Door Technologies, Inc. can install the hardware and configure your pc's to securely communicate with another pc across town or across the globe.

VPNs require each site to have a static IP address
(the internet address of your Cable/DSL modem never changes).  This allows the internet connection to provide up to 128 bit security encryption between the two locations when sensitive data is being sent from one pc at one location to another pc in another location.  Files and Printers can even be shared across a VPN connection just as if they were on the same network in the same room.
