Probably this is one of the biggest questions in the world of technology right now is should we use a VPN? Over the years technology has changed and most long term users realize we need an antivirus and a firewall right? I remember when firewall software was first introduced. Now we have something that is new for even residential users. It's called a VPN. The technology has been around for a while more commonly used for businesses. VPNs can be set up in many ways in some cases requiring special software or a connection to the network via wifi or ethernet.
In time many things change. Basically a short answer to whether we need to use a VPN is yes and no. If you're using your computer for work or company level tasks and need to connect to local drivers, printers and other computers like servers then you will need to use a VPN. Using a private VPN made by your company's IT team provides an extra layer of security.
While using a free or public VPN service you may actually increase your risk of cyber attacks. Public and free VPN services are more like a tool than an actual security application.
Although there is a need for these services for some types of work, if you want to search foreign sites or gaming. The highest form of security while using a VPN is to build your own network or have an IT professional setup your private VPN.
Installing a VPN is fairly simple. There are many free or paid versions. A Lot of VPN services also offer a free initial or limited trial. A highly recommended VPN service that offers easy VPN setup and configuration for Windows, Mac, IOS and Android is TunnelBear. TunnelBear offers VPN connections to about 40 countries including the US, Australia and Canada.
TunnelBear is the quick easy solution for a non technical individual who wants to have a VPN for accessing overseas content, websites and more. The security is very mild. If you are interested in implementing a VPN for a corporation then you should hire an IT professional to install a ISP, server, network and firewall system for your business. Private VPNs have the highest level of security plus they give you full monitoring abilities and control over the users within the network. TunnelBear, like other paid membership VPN services, are considered public VPNs because many people can join the same network.
Here is a list of some of the popular open source VPNs.
Aside from TunnelBear there is ExpressVPN and NordVPN which are very popular. You may experience less configuration issues with TunnelBear because of its user-friendly technology. Overall if you are in need of a VPN and want to access foreign sites Public VPNs are good. For internal networking and security a custom private VPN is needed or best.
