How do VPNs Save Money?

Thanks to a relatively inexpensive, local dial-up or broadband connection, companies using VPNs save on telecommunications costs and long-distance phone charges. Companies also cut down on operational costs by outsourcing the management of equipment used for remote access, as well as reducing the number of access lines running into a corporate site. In some cases, the company can "borrow" the necessary hardware from a VPN service provider, at no extra charge. Finally, a VPN can theoretically alleviate the support burden. The public service provider is generally responsible for supporting its dial-up customers.
