Abstract: The Virtual Private Network (VPN) is a rapidly developing technology that has a crucial function in guaranteeing the secure transfer of data. A virtual linkage is created among geographically distant individuals and networks that are linked through a common or public network, such as the Internet. Despite the fact that data is transmitted via a public network, a Virtual Private Network (VPN) signifies that the data is conveyed through a secure and private connection. Virtual Private Network (VPN) technology enables secure communication between two hosts by creating virtual tunnels. Upon the establishment of a tunnel, it becomes possible to transmit data between the two servers. This paper provides a comprehensive analysis of Virtual Private Networks (VPNs), including their historical background, architectural design, employed protocols, and identified vulner- abilities. A Virtual Private Network (VPN) is implemented to secure the private network by utilising encryption and other security measures, thereby ensuring that solely authorised users are granted access to the system and preventing data interception. This survey comprehensively covers the topics of Virtual Private Networks (VPNs), their protocols, and the security measures implemented within VPNs. The present article has conducted an overview of the diverse protocols employed in the domain of Virtual Private Networking.
