VPN fundamentals
How does a VPN work?
A VPN client establishes a protected connection to a VPN gateway, then sends selected traffic through that connection. The device, gateway, route configuration, and destination each remain separate parts of the path.
What can a VPN protect, and what can it not protect?
A VPN can protect a defined connection path between a device and a VPN gateway. It does not replace safeguards on the device, account, or destination.
VPN vs proxy: what is the difference?
A VPN and a proxy can both relay traffic, but they can differ in coverage, routing, configuration, and the trust boundary they create. The right choice depends on the application and the use case.
What is a VPN?
A VPN creates a logical network over an existing network and can carry traffic between a device and a VPN gateway. It improves the connection path in some situations, but it does not remove every device, account, or destination risk.
