To offer privacy and security VPNs encapsulate all data transfers that are online by using some innovative encryption protocols and protected tunnelling methods. These innovative encryption protocols operate on various Operating Systems such as Windows, Mac, Linux, Android, iOS and so forth. Below are a few examples of common protocols used in VPNs.

This innovative Layer 2 Tunnelling Protocol (L2TP) utilizes in conjunction with Internet Protocol security (IPsec) is much more secure than PPTP. It’s more features using a cryptographic security solutions to safeguard communications over IP networks
