L2TP builds a tunnel between two connection points. IPSec protocol maintains encrypting secure communication between Tunnel.


Point-to-point protocols are used to encrypt Data between connections. Pptp, the most popular VPN protocol, has been used since the early days of Windows. In addition to Windows, VPN can also use Pptp on Mac and Linux.

4) OpenVPN

OpenVPN, an open-source VPN, is used to create point-to-point and site-to-site connections. It uses a traditional security protocol based on the SSL/TLS protocol.

5) SSH

Secure Shell, or SSH, generates VPN tunnel through which Data is transferred. It also ensures that encryption is used. A client can create ssh connections. The location from the remote Server is transferred from Data through the port encrypted tunnel.

6) SSl & TLS

SSl (Secure Socket Layer), and TLS (Transport Layer Security), create a VPN connection where the web browser acts as a man.

This allows users to access the restricted app and not the entire network. Many online shopping sites use SSl and TLS protocols. Since SSl and TLS are integrated into web browsers, it is easy to switch to SSl. SSl use “Https” instead of “Http” at the beginning of the connection Url.
