Local Area Networks (LANs)
If you are a business that operates in many locations or often has employees work from home or while on business trips, Virtual Private Networking is a great way to stay connected. Having a business VPN (Virtual Private Network), is an excellent way for companies to allow their employees to remotely access the companies data, quickly and efficiently.
What is it?
A VPN works by using a public network (usually the internet) to connect remote sites or users to the company's server from anywhere in the world. When a VPN is routed through the Internet it is viewed as a direct link from the remote access-point to the server. Each employee can then sign onto the server from their home, a hotel while travelling, or their cottage on the weekend, allowing them to access all their digital work files.
To explain VPN further, there is an image that is frequently used to clarify it. The analogy is that each LAN (local area network) is an island, and while bridges are great ways to connect to mainland they can be costly if you need to constantly be building bridges to connect the multiple LANs your employee's visit. The total cost of the multiple bridges is expensive as it the maintenance for the ongoing servicing of all the bridges. A submarine on the other hand could shuttle employees to all the islands or LANs they need to go to. One submarine could replace all the bridges. Submarines can also cover larger distances than a bridge. In the same way as a submarine a VPN allows for speed, efficiency, security and secrecy for a company's data transfer.
There are three types of VPNs:
1) Remote Access VPN: This is used by a client with a single computer who connects to a private network. The VPN client, once authenticated to the VPN server, can access the network.
2) Site-to-site VPN: Typically used for larger organizations, a site-to-site VPN allows companies to have routed communication through different offices or other groups. It operates as a Wide Area Network (WAN) link.
3) Internet-based VPN Connections: This essentially allows companies use the infrastructure available through the internet to connect all its business locations where ever they are in the world
Why pick a Virtual Private Network?
A VPN is much cheaper than many options available because granting additional employees access does not add any additional cost, it is as simple as giving them a user name and password. One of the most attractive benefits to a business VPN is that while on business trips employees are still able to access all their information via the internet. This is also beneficial for workers who live in more remote areas. For example, in a snow storm they could still “show up” for work because they would be able to access the company's server and work from home. With a VPN the data is also encrypted, so it improves security for your company.
All in all, Virtual Private Networks are a cost-effective, simple, secure way to connect all your employees to the company’s server.
