What is VPN ?

A Virtual Private Network (or VPN) is an online service that creates a secure connection to another network over the Internet, hides your IP address, and encrypts your traffic to effectively shield you from your ISPInternet Service Provider and government. VPNs are frequently utilized by corporations to secure sensitive information. However, utilizing a personal VPN is progressively getting more mainstream as communications transition from up close and personal to the Internet.

Security

Security is the main reason why corporations use VPN. VPN’s use advanced encryption protocols and secure tunneling techniques to protect all online data transfers. Developing security dangers and our consistently expanding dependence on the Internet make VPNs a basic piece of security. Integrity checks ensure no data is lost and the connection has not been hijacked.

How VPN works

A VPN consists of two components: a software client on a remote computer and a concentratorA VPN concentrator is a networking device that provides secure creation of VPN connections and delivery of messages between VPN nodes. It is a type of router device built specifically for creating and managing VPN communication infrastructures.. The software client lets users establish an encrypted “tunnel” with the concentrator. This encrypted tunnel prevents other users on the Internet from being able to easily view the encrypted data sent/received by the user.

Setting up a VPN

Setting up a VPN is a simple process that is frequently as straightforward as entering a username and server address. Smartphones can configure VPNs using PPTP and L2TP/IPsec protocols, and all major operating systems can configure VPN using PPTP protocol.
