VPN
abbreviation for Virtual Private Network
VPN serves to integrates devices from a neighboring net-
work into your own network, without the networks having
to be compatible with each other.
A VPN is generally an independent company network dis-
tributed over several locations, which uses the infrastruc-
ture of a public communications network to link its partial
networks or to link individual computers to the rest of the
network. A VPN uses tunneling technologies and typically
builds on the infrastructure of the Internet.
Using a Virtual Private Network it is possible to use all net-
work applications of the company network even from dis-
tant locations. This means it is possible to use the advan-
tages of the network even over large geographical distanc-
es.
VPN facilitates optimum information flow without delay
throughout the entire company, even to offices in other lo-
cations. E-mail servers, file sharing and other central ap-
plications of the company network can thus be made
available via VPN even to distant branch offices, subsid-
iaries and home offices. With VPN, field representatives of
a company can also be granted secure access to the com-
pany network.
