A virtual private network (VPN) brings added security to anybody using a public network, like the World Wide Web. With a variety of security techniques, including encryption, the VPN can safeguard any information transmitted from the other side of the network, which might be in danger if it just used the inherent network infrastructure that is public. VPNs are frequently used when it would not be practical to utilize a physical private network, generally because of monetary reasons. As companies face increasing pressure to guard sensitive information and adopt mobile working, many are using virtual private networks to enhance their network security.

There are just two primary kinds of VPNs now used by organsiations: site and remote access -to-website. A remote access VPN uses the inherent network that is public to give users access to the private network of an organisation.

Website-to-site VPNs may use a number of gear and the exact same applications as a remote access VPN, but is generally used for a function that is somewhat different. Website-to-site virtual private networks usually connect entire networks based in a single place to a different network found someplace else. This may prove to be incredibly helpful for companies with numerous departments based in disparate places, or organisations that want to share resources with a client or partner company. Businesses that use a website-to-site VPN can reap the benefits of increased cooperation without worrying in regards to the security of their information.
