VPNs, or Virtual Private Networks, are the solution to creating long-distance, secured network connections. Usually, a VPN is used by businesses and organizations, but you can use them in a home network as well. A VPN provides many benefits for the organization using it, particularly in the field of local area networking.
VPNs provide three major advantages- cost-savings, ease-of-use, and network scalability. These three benefits typically outweigh the potential disadvantages of using a public network connection for business use.
Cost Saving Benefits
Using a VPN will save money because it eliminates the need for long-distance leased lines, offloads support costs, and reduces long-distance telephone charges.
In general, an organization must rent network capacity to create a secured connection on their network between office locations. A VPS saves money by using a public network to create these connections. The connection is still secure, but at a reduced price. A company can also save on long distance phone charges, because a VPN replaces the remote access servers that are required to use a company intranet from a long distance.
Network Scalability Benefits
When an organization grows, the costs of creating a private network increase as well. If a company has more than 2 locations, the number of direct connection lines increases exponentially. A company with just 4 branches requires 6 direct collection lines. A company with 6 offices has to have 15 connection lines.
Using a VPN avoids this problem. A VPN uses the public lines and networks already in existence, which saves a company a huge expense. The VPN keeps the data secure, but eliminates the expense of creating direct lines. A VPN also makes it possible to reach further and with greater quality of service.
A VPN is much easier to install and use than a direct connection line. Installation is virtually non-existent as the company can tap into existing network lines. It is also easier for users as they can access the network from anywhere in the world. Each computer acts as a terminal for the data housed somewhere else and connected through a traditional, public network.
Drawbacks of VPNs
There are a few drawbacks when using a VPN that are important to consider before choosing to use the technology. You must make sure that your installation team knows how to configure the network to ensure maximum security. The reliability of the network will depend on the VPN Company that you choose. Some ISP connections are worse than others, so it is extremely important to choose a reliable company. Some VPN companies are not compatible with other VPN or network components. It is important to choose a provider that is compatible with the equipment that you plan to use.
The best VPN to buy online is one that is compatible with your existing business intranet and the surrounding network connections. You should also choose a company that has a quality, reliable ISP because your company’s connection success will depend upon the reliability of the ISP and VPN network that you choose.
