Virtual Private Networks (VPN)

What is a Virtual Private Network?

A Virtual Private Network can be used in many different ways. It can mask your IP address to watch region blocked content from international websites that block connections from Australia. It will protect your privacy on WiFi connections especially at public places such as coffee shops and airports as well as simply connecting to network devices at home or work from wherever you are in the world securely.

But in most cases a VPN can be a very powerful tool for any business to implement. A VPN can connect two different geological branch offices into the one network, allowing and increase in productivity and accessibility. For employees that travel to lots of different locations, having a VPN tunnel back into the office on their laptop can ensure that all the work can be transferred in a secure manner.

How does it work?

When a network device connects to a VPN it creates a private tunnel shielding data from anything in between which may be intercepted by hackers. Once that data has been sent to the VPN server it can then send the packets back out to another device on it’s local network or back out to the internet towards another server. This will give  you the ability to connect to Facebook or your file server at home securely from an otherwise insecure network.

How can I use a VPN?

You can use free or paid online VPN services.  However, usually the free services are unreliable . I myself would use either a paid VPN or run your own at work or home. One of the paid VPN services I do recommend is VyprVPN. In a commercial environment one of the most secure VPN solutions is OpenVPN, Tech Check is currently working on an extensive project involving the OpenVPN software.
