Wide Area Networking & VPN Services






The benefits of a local area network, or LAN, based at one site within a company are universally recognised. However, you may have reached a point where you have more than one site, perhaps each with its own network and you now wish them to communicate with each other. A wide area network, or WAN, is the solution.

A wide area network extends your existing network using external communications technologies such as ISDN, ADSL, leased line or even over a standard internet connection using virtual private networking (VPN). There are many options and not all of them will be right for your company.

USIC can help you make the right choices. Our consultants can provide an independent and professional assessment of your WAN needs. They will present their findings and recommend a solution that is right for you, based on your technological needs and supplier costs, ensuring you get the right solution at the right price.

Virtual Private Networking, or VPN, is becoming ever more popular as a WAN solution. The only connection needed at each site to establish a VPN is a standard connection to the internet, this is used as the basis for a secure virtual network.

The most immediate and obvious benefits of this are cost related, since you neednít have expensive dedicated lines installed at each of your sites. Indeed a VPN can be up to 90% less expensive to implement than the alternatives. Indirect benefits might include routing voice calls between sites through the VPN to reduce communications costs.

The other major benefit of a VPN is that your employees can securely access the company network from anywhere in the world.

This has great potential for home-working or allowing employees on the road or at client sites to directly access your LAN and use resources or access information.

It also has excellent potential as a tool for technical support. In many cases a field engineer can resolve problems with your systems immediately via VPN without the need for the added cost and time involved in an on-site visit.

VPN also has its downsides. Since it requires the use of the internet it may cause problems for applications that require low latency and, of course, speed may be an issue. USIC will be able to help you determine if a VPN is right for you, as well as installing, configuring and supporting your VPN once it is in place.
