What will be an ideal response?

There are several advantages of VPN technology.These include:
* Cost savings-VPNs can eliminate the need for an expensive long-distance leased connection.
* Scalability-With VPNs, additional users can be easily added to a hardware-based VPN simply by connecting that device to the existing network.
* Full protection-VPN encrypts all transmissions from the client and not just certain applications.
* Speed-Compared to dial-up connections,VPN can provide dramatically increased bandwidth. VPN can also compress data and increase the speed of the transmission.
* Transparency-Once a VPN is set up it is basically invisible to the user.
* Authentication-VPN can ensure that only authorized users have access to information.
* Industry standards-VPNs can take advantage of industry-wide protocol standards such as IPsec.
