A virtual private network (VPN) extends a private network across a public network. It acts as if your device were directly connected to the private network. VPNs add a level of security that enable you to access private data and secure transactions remotely. You can surf the web through a VPN to ensure privacy and security.
Using public WiFi for access to personal and private data is unsafe, and a VPN is an added measure to protect you from unwanted access. It virtually creates a point-to-point connection or tunnel. Once you are inside the tunnel it becomes difficult for anyone to see or capture your activity.
VPN is actually a service. It directs your web traffic to go through the VPN server to arrive at its destination. Only the VPN server and the website you’re visiting know what you are doing.
VPN services are available for PCs, Macs and mobile devices. There are paid and free versions. Do some research before choosing what works best for you. Some of the drawbacks of the free versions will include bandwidth limitations and ads.
