What is a VPN and How to Choose the Best for Your Business
A VPN is very useful for your mobile employees such as sales and service teams as well as remote employees as it allows them to easily access company resources using any high speed internet connection, which helps them work efficiently and securely while working remotely.
If you have read our previous blog about different types of computer networks, you may be wondering why you cannot create a WAN using a leased line instead of using a VPN. This is a good idea but may not be suitable here because a VPN has the following advantages:
Dedicated WAN links that use leased lines are expensive. With a VPN, you can use the Internet as a means to connect users and remote offices in a cost-effective manner.
WAN links for leased lines are site to site. So it will connect your offices but remote employees working from home or mobile employees such as sales and service teams will not benefit from it. The mobility that a VPN provides is unparalleled here.
Since VPNs take advantage of third-party infrastructure i.e. the internet provided by Internet Service Providers (ISPs), it is easy to add or remove users without affecting your bandwidth.
What are the different types of business VPNs?
VPNs can be broadly categorized into two types:
1. VPN Remote Access
A remote access VPN works by creating a “virtual private” connection between an organization’s network and a remote user. It consists of two main components:
A dedicated server, network access server, or software application on a shared server connected to an organization’s internal network.
VPN client, any software application installed on the user’s computer or mobile device.
When the user activates his VPN client, it creates a tunnel to the network access server. Traffic in this tunnel is encrypted, and therefore incomprehensible to eavesdropping. Therefore, data can be transmitted over the Internet without fear of being intercepted or tampered with.
