A virtual private network (VPN) is a method by which a secure network communication can be achieved anywhere – at home, at a coffee shop or at the office. A VPN is very simple to set up, and often does not need to be re-configured. Use of proper network security techniques is absolutely essential for businesses looking to keep their data private, and out of malicious hands.
How Does a VPN Work?
A VPN keeps your data safe by funneling all of your network traffic through a secure IP address. This IP can be made to represent a location anywhere in the world. This protects data by adding a level of obscurity to it, and also protects by not allowing the data to be seen in the traffic.
Why Does It Keep My Network Traffic Safe
If you were to use the public WiFi network at Starbucks or any other shop, all traffic on that network would be open to anyone else on that network. If you are working with sensitive business or financial data, this data could become comprimised and possibly even fall into malicious hands. A VPN acts like a sort of tunnel for your network data. It allows all of your data to pass through the tunnel, safe from spying eyes that may be watching. Any onlookers can only see the wall of your tunnel, not your actual data.
Who Should Use a VPN
A VPN is something that is so simple to setup and use that I recommend that everyone utilize one. The only usage case where a VPN may give a negative experience is when completing tasks that require that best possible ping/latency. Due to the secure nature of the VPN, some milliseconds of latency will be added to the connection. However, this is unnoticeable when completing regular tasks. Data transfer speeds are not affected.
