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.
