The best option for remote connections on a WAN

To connect to a WAN remotely, your client can use a VPN client or a leased line. Learn the pros and cons of WAN connectivity with each option, such as which one is more efficient and which one is more economical.

Which is the best option—a VPN or a leased line—to connect a client's home office to regional offices on a WAN?

Unless there are some unusual circumstances, it is almost always better to use a VPN. Leased Lines Anywhere, a site that offers a leased line comparison service, says that a T1 line generally costs between $499 and $1250 per month. ISDN solutions are cheaper, $40 to $120 for a 64Kb line plus $19 to $50 for an ISP, if you need one, according to Broadband Reports.com. In addition, ISDN services often have usage restrictions.

On the other hand, you can expect to pay far less (typically $40 to $100) for a cable or DSL Internet connection with speeds ranging from 768Kb to 15 Mb per second. Because the security of a VPN is comparable to a leased line, there is normally no reason to use a leased line if there are Internet broadband solutions available.
