A Virtual Private Network (VPN) allows for the extension of a Local Area Network (LAN) to geographically dispersed sites. VPN is greatly beneficial as it allows your office network to be extended to other sites and to remote users. Several variants of VPNs exist and One Metric is able to design, implement and support all of them.
Site to Site VPN
A Site to Site VPN allows for a VPN to be created over the internet. An Encrypted Tunnel is created over each site’s internet connection. All data between the sites travel over this encrypted tunnel preventing the threat of data being intercepted and reviewed. Several authentication methods exist to prevent unauthorised users attempting to connect and gain access to the VPN.
Remote Access VPN
A remote access VPN allows for a remote user to form an encrypted tunnel similar to a Site to Site VPN. It supports multiple users connecting from different locations to a central office, allowing them to have access to resources from anywhere with an internet connection. Client software installed on the Remote Users PC creates the tunnel and provides a method for the user to authenticate with the Office, either using their Windows Login or another Login.
A MPLS VPN creates a true Private Network. Data never travels over the internet so encryption is no longer needed. Each site appears as an extension of each other. Any data transferred between sites is not counted towards your Data Quota. It is extremely scalable and extendable. Servers can be moved from your office into a high availability data centre, minimising the risk of problems if one site loses connectivity. Extension of this VPN allows for Remote Access from Remote Users.
