What is the role of virtual private networks (VPNs) in network security?

The role of virtual private networks (VPNs) in network security is to provide a secure and encrypted connection between a user's device and a private network over the internet. VPNs ensure that data transmitted between the user and the private network remains confidential and protected from unauthorized access. They also help in establishing secure remote access to a private network, allowing users to securely connect to their organization's network from remote locations. Additionally, VPNs can be used to bypass geographical restrictions and maintain anonymity while browsing the internet.
