What is the role of a virtual private network (VPN)?

A virtual private network (VPN) serves the primary role of securely connecting remote users to a network, often over the public internet. By establishing encrypted connections, VPNs protect data in transit, ensuring that sensitive information cannot be easily intercepted by malicious actors.

When users connect to a VPN, their device communicates with a VPN server, which masks their IP address and creates a secure tunnel for data exchange. This helps remote employees securely access company resources, such as files and applications, as if they were physically present in the office.

This functionality is particularly crucial in today's remote work environment, where employees frequently need access to sensitive data from various locations. The security benefits provided by a VPN, including data encryption and anonymity, make it an essential tool for maintaining data integrity and confidentiality in remote connections.
