The Full form of VPN is Virtual Private Network. VPN refers to an encrypted and safe network that allows you to use network resources in a remote manner. It is constructed using public wires, usually, the internet, to connect remote users or regional offices to a company’s internal, private network. Using Virtual Private Network, you can create a safe connection over a less secure network, usually over the internet. It is a secure network as it is completely isolated from the rest of the internet. The businesses, military, and government can use this network to use network resources securely.
A VPN uses a site-to-site and remote access methods to work and it is free to use. To establish a secure connection, it uses an arrangement of encryption services. It is an ideal tool for encryption; it provides you strong AES256 encryption with an 8192bit key. Using powerful VPN protocols, it creates a secure tunnel and hides your IP address behind its own IP address that encrypts all your communication.
To create secure networks, there are several different VPN protocols that are used like; IP security (IPsec), Point to Point Tunnelling Protocol (PPTP), Layer 2 Tunnelling Protocol (L2TP), Secure Sockets Layer (SSL) and Transport Layer Security (TLS).
