What is a VPN?
A VPN or Virtual Private Network is a network connection that enables you to create a secure connection over the public Internet to private networks at a remote location. With a VPN, all network traffic (data, voice, and video) goes through a secure virtual tunnel between the host device (client) and the VPN provider’s servers, and is encrypted. VPN technology uses a combination of features such as encryption, tunneling protocols, data encapsulation, and certified connections to provide you with a secure connection to private networks and to protect your identity.
VPN connections technically give you all the benefits of a Local Area Network (LAN), which is similar to that found in many offices but without requiring a hard-wired connection.
Early VPNs were often set up to give individual employees secure remote access to their company networks, hence the name “virtual private network”. By connecting to the company’s network, an individual employee can access all the company’s resources and services as if the employee were inside the company.
Since then, VPNs have evolved to provide the same level of secure communication between any device on the internet. Today, using VPN is increasingly popular among consumers as a means to protect their privacy online, secure their browsing sessions, and get unrestricted access to content or websites that are otherwise blocked or censored.
