VPN
A VPN (Virtual
Private Network) is created
using the public Internet. A VPN uses encryption and
authentication methods to ensure that only authorized
users can access the network and that the data cannot be intercepted or
altered.

-
Offload support
burdens to local ISP (Internet Service Provider) and not the IT professional at the
branch
-
Scalability of

using leased lines
