This can add significantly to the hidden costs of using a VPN and come as a shock to an IT manager. After all, VPNs are widely viewed as a cost saver. In most cases, a VPN can significantly reduce monthly communications charges. But what should really be considered is the total cost of ownership associated with VPNs. While communications costs are highly visible and easily quantifiable, the operational costs of using a VPN also should be taken into account.
Time is money.
If an IT staff spends several hours a day supporting remote VPN users, the costs add up. What's really needed is a VPN client with an integrated dialer functionality. This would reduce operational costs by simplifying software distribution, installation and configuration tasks. An integrated program also could cut costs by eliminating any potential conflicts from two programs trying to use some of the same resources. Microsoft has done the most when it comes to addressing VPN client issues.
