VPNs make it possible for businesses and individuals to communicate and transmit data over a wide area network. The cool thing with VPNs is that you are able to send private information over public channels. Since VPN relies on WAN connections, computers connected to the network don't need to be physically nearby-they can be countries or even continents apart and they will communicate perfectly.
Types of VPNs
There are many types of VPNs with the main ones being:
Virtual private dial-up network (VPDN). This is a user-to-LAN connection where users have to connect to the company LAN. As a company owner, you need to set up a NAS (network access server) and then provide your users with software that will enable them to reach the NAS from their computers.
You should note that this type of VPN requires a third party to provide encryption services.
Site-to-site VPN: as a company owner you have to invest in dedicated hardware that will make it possible for your multiple sites to connect to your LAN through the public network. It's good to note that most of the site-to-site VPNs are extranet or intranet-based.
Benefits of VPN
There are a good number of benefits that come with VPNs. These benefits include:
Business application: if you have a business you are able to maximize the businesses efficiency courtesy of VPN. Using VPN your employees are able to connect to the computers in the office network using their personal computers at home. The employees are able to access messages, documents and other information. This ensures that the employees don't have to wait to report to the office to start working-they can work from home.
In addition to employees being able to access information from home, different office branches can connect to the VPN and share confidential information securely.
Protection: as a regular consumer you can use VPN to access Wi-fi or other loosely secured network. The cool thing with accessing Wi-fi using VPN is that you add a layer of protection against information theft.
This is what you need to know about VPN. You should note that while the network is great to use, it tends to reduce your transfer speeds due to the additional network overhead involved. It's also challenging to set it up for the first time as a novice. For ideal results, you should hire a professional to do the work for you.
