A common use of a virtual private network (VPN) is to ensure secure internet browsing. VPNs create an encrypted tunnel between a user's device and the internet, preventing unauthorized access to sensitive data. They are widely used by individuals seeking privacy while surfing the web, as well as businesses to protect employee communications and access company networks remotely. VPNs also allow users to bypass geographical restrictions, enabling access to content that may be blocked or restricted in certain regions.
