Virtual Private Network. In the world of technology we talk about different layers of connectivity. If a direct, physical connection from one system to another is not available then a connection via other means may have to be created.

A VPN creates a ‘software’ connection from one location to the other in order that a private tunnel is created. Varying degrees of security can be applied to such a tunnel. Interhost can setup and manage you VPN connections using managed firewalls.


This is a primary method for keeping a computer secure from intruders. A firewall allows or blocks traffic into and out of a private network or the user's computer. Firewalls are widely used to give users secure access to the Internet as well as to separate a company's public Web server from its internal network.

SIP technology allows companies to use their existing Internet connectivity to make calls, as opposed to operating with analogue or digital (ISDN) services. Many of our MPLS customers have quality of service capable WAN links between their sites and already use their WAN for inter-site VOIP. For those customers, adoption of SIP trunking is the next logical stage in their evolution as they already have a network that is voice ready. Almost every new Interhost connectivity customer is either undertaking a limited-scale SIP trunking rollout, or is planning on doing so, even if they are not yet considering a complete ISDN replacement.
