Virtual Private Network 

Yes we do install Virtual Private Networks.

Virtual Private Network (VPN):
Have you ever wanted to add a computer at another location to the network in your office?  You could benefit from a VPN. Using DSL or even a satellite uplink, with a VPN you can virtually extend the computer network in your office around the world.  
What is a VPN?
A VPN is a “Virtual Private Network.”  Unlike a truly private network where you own the wires all the way from point A to point B and nobody else can use them, in a VPN some part of the path from A to B is a public network such as the Internet, a public telephone system or even satellites. The VPN provider builds a "tunnel" through that public system for your private data traffic. 
VPN or Virtual Private Network describes a network that includes secure remote access 
for client computers. It can be explained best by looking at its parts. Virtual describes the fact that the network doesn't need to be physically connected. The Private confirms that the data is encrypted and can only be viewed by a defined group. The last word, Network, means that the users configured for VPN can be connected and share files or information.
For instance, field representatives for a company can work on the home offices network over the Internet. This access will have the same look and feel as if they are back at the office physically connected to their network, except the reps are working at the speed of their local modem. The data is sent to and from the reps (or to and from the network) encrypted, so it's extremely difficult for anyone to snoop on confidential information. IPSEC is one of the best VPN solutions. It connects networks via the Internet using encrypted traffic, so an office in San Francisco can share different files and data with an office in Boston in a secure fashion. IPSEC also allows Windows 2000 or Windows XP client machines, which support IPSEC by default, to connect to Real Time Firewall.

What benefit does this bring?
Virtual Private Networks offer a very cost-effective way for corporations to communicate. Connection is generally based on inexpensive local call ISDN or telephone connections using the Internet as the main communications link.

An intranet allows you to post critical information for all employees to see. Even having human resources information posted is valuable. One of my employees said workers in his former office once spent 45 minutes trying to find out if the day after Thanksgiving was a paid holiday. The personnel manager was gone and no one else knew.

Posting of calendars, company policies and company benefits is a great start. They'll reduce wasted time. But an intranet can be used for more than basic information. 

Are there any drawbacks?
With a true private network, a user can expect, and demand, a defined minimum quality of service from the telephone company or provider. However, a Virtual Private Network could depend upon many sections of the Internet that are beyond the control of your ISP (Internet Service Provider).  Also, the speed of the VPN is limited to the connection speed.  A typical internet connection is not as fast as a connection over a LAN.

How secure is a VPN?
Understandably, the corporate world has concerns about sending sensitive information over the very public part of a VPN, the Internet. In practical terms, information passing over the VPN will potentially be routed across several networks that are not under the control of the sender. Thus an important part of any VPN is the encryption that will secure the data stream from prying eyes. Hence, the development of IPSec, which provides both these functions and more.
