VPN (Virtual Private Network)

A technology that securely extends a private network across a public network, allowing users or multiple networks to connect as if they were directly linked to the private network. A VPN creates an encrypted tunnel that protects data integrity and confidentiality while in transit. This enables remote users to securely access private resources and allows organisations to securely connect multiple office locations over the internet.

Example: A company uses a VPN to connect its headquarters' network with branch offices, allowing employees to share resources and data securely between locations.
